Byung-hyun Kim

He made his first career postseason appearance in the NLDS Game 3 at Busch Stadium to protect the Diamondbacks’ 5–3 lead against the Cardinals with the go-ahead run at the plate in the 8th inning. After a walk to Albert Pujols that loaded the bases, Kim ended the inning with a center-field flyout. In the 9th inning, Kim saved the game with the game-ending double play off Mark McGwire's bat.

On April 10, 2014, he was traded to the Kia Tigers.

In the NLCS against the Atlanta Braves, Kim worked a scoreless inning in Game 2, in which the Diamondbacks lost. Kim then picked up saves in Games 4 and 5 for the Diamondbacks. Kim entered Game 4 in the 8th inning with the Diamondbacks leading 7–3. However, prior to Kim entering the game, The D-backs had worked themselves into a bases loaded jam with no one out. Kim pitched masterfully in the inning, ending the bases loaded jam with a double play and a lineout. He then retired the next three batters in the 9th inning and picked up the save. The next night, Kim pitched another two shut-out innings and earned the two-inning save that clinched the Diamondbacks’ ticket to the World Series. Kim became the first pitcher since Goose Gossage to earn two-inning saves on back-to-back days in the postseason. In the 2004 postseason, Houston Astros closer Brad Lidge matched Gossage and Kim's feat.

With the Diamondbacks up two games to one going into Game 4 of the World Series, Kim relieved Curt Schilling in the eighth inning with the Diamondbacks leading 3–1. Kim struck out Shane Spencer, Scott Brosius, Alfonso Soriano, and Bernie Williams and grounded out Derek Jeter. But Paul O'Neill hit a single off Kim before Williams' plate appearance and Tino Martinez's two-out, two-run home run tied the game in the bottom of the ninth inning. With another home run hit off Kim by Jeter in the bottom of the tenth, the Yankees won the game and tied the Series. Kim threw more than 60 pitches and was charged with the loss. The night after, in Game 5, Diamondbacks manager Bob Brenly sent Kim again to the mound to protect the Diamondbacks' 2–0 lead. Jorge Posada hit a leadoff double off Kim, and after retiring Spencer and Chuck Knoblauch on a groundout and strikeout, Brosius then hit a two-run home run to tie the score. Later, Soriano hit a single in the bottom of the 12th to win the game.

When Matt Mantei returned from the disabled list and became the Arizona Diamondbacks' closer, Kim joined the starting rotation. As a Diamondbacks starter, he compiled a record of 1–5 with a 3.56 ERA. On May 29, Kim was traded to Boston for Shea Hillenbrand. Kim remained as a starter through June, but the Red Sox needed him as their closer because the Red Sox's closer-by-committee approach implemented following the advice of statistician and Red Sox adviser Bill James was failing. On June 27, Kim made his final start for the 2003 season in Boston's 25–8 win against the Florida Marlins at Fenway Park.

As a starter, Kim went 3–6 with a 3.38 ERA in 12 appearances in 2003. In the beginning of 2004, however, problems with his balance—a lingering effect of the 2003 ankle injury—made him ineffective and cost him a spot in the starting rotation after going 1–1 with a 6.17 ERA in three starts. Bronson Arroyo took Kim's starting rotation spot and Kim was optioned to Triple-A Pawtucket in May. Kim rejoined the Red Sox in September. He was assigned to the bullpen and won one game in 5⅔ innings of work. Despite not being on the Red Sox roster for their 2004 World Series championship run, he was awarded his second World Series ring by the team.

Rockies manager Clint Hurdle gave Kim the choice of taking a spot in the bullpen (Kim posted 0–3 with 7.84 ERA as a middle reliever for the Rockies that season) or a starter position in the Rockies' Triple-A team Colorado Springs Sky Sox. Just 20 minutes later, Hurdle was told that Rockies starter Shawn Chacón was injured and had to go to the disabled list, opening a spot in the Rockies starting rotation for Kim.

On January 18, 2012, it was announced that Kim signed a one-year deal with Seoul-based team Nexen Heroes of Korea Baseball Organization.

On February 1, 2010, Kim agreed to a minor league contract with the San Francisco Giants. On March 20, 2010, the Giants granted him his release after he appeared in just one minor league game. Kim later played with the Orange County Flyers of the Golden Baseball League in 2010.

On February 24, 2008, Kim signed a contract with the Pittsburgh Pirates. The Pirates had planned to use Kim exclusively in the bullpen. Kim made his first spring training appearance on March 10, 2008. After a disappointing spring training performance, Kim was released by the Pirates on March 25.

Kim began the 2007 season with the Colorado Rockies as a reliever after he lost his starting rotation spot to Josh Fogg. The Rockies' decision to move Kim to the bullpen was controversial. Kim contended that he was not given a fair opportunity during Spring training to compete for a starting spot and asked to be traded.

After a spot start on April 15, Kim was placed on the disabled list with an injured thumb. He was assigned to the Rockies' Triple-A team, the Colorado Springs Sky Sox, for a rehab assignment. Kim was concerned that his rehab assignment was longer than necessary and changed his agent to Scott Boras in an effort to get a quicker trade. On May 13, 2007, he was traded to the Florida Marlins for Jorge Julio. As a Marlin, he proved himself as a dependable starter.

On August 25, 2007, the Florida Marlins re-signed Kim as a free agent.

Kim represented Korea in the World Baseball Classic, a tournament held during spring training before the 2006 season. Kim was credited with solid shutout middle relief performances during the tournament in Korea's wins against Taiwan in the first round and Japan and the United States. in the second round. Kim collected a relief-win against Japan in the second round. In the semifinal game against Japan, Kim relieved Jun Byung-doo in the 7th inning and then allowed a two-run home run to Kosuke Fukudome. Kim intentionally hit the next batter Michihiro Ogasawara. Korea lost the semifinal game and finished third in the tournament.

Kim began the 2006 campaign with the Colorado Rockies on the disabled list. Upon his successful rehabilitation, he made his season debut on April 30, 2006, against the Florida Marlins in Miami. Kim pitched impressively, giving up only one run on five hits while striking out nine batters. Kim established himself in the Rockies starting rotation for the season.

On May 22, 2006, Kim and his former high school teammate and then-Los Angeles Dodgers' starter Jae Seo started against each other. This game was the first game in which two Korean pitchers started against each other in the Major League history. Both pitchers had quality starts, with Seo getting the win.

On July 28, 2006, Kim had five consecutive strikeouts against the San Diego Padres, tying the Rockies record for consecutive strikeouts. In four different starts, he recorded nine strikeouts each against the Florida Marlins, Houston Astros, Pittsburgh Pirates and Washington Nationals. Kim became the only pitcher in Major League history to pitch shutout wins in consecutive starts at Coors Field by beating the Oakland Athletics on June 19 and the Texas Rangers on June 25.

Before the 2005 season, the Red Sox sent Kim to the Colorado Rockies, with general manager Theo Epstein calling the two-year deal given to him in 2004 "a mistake." Kim was traded for left-handed pitcher Chris Narveson, who was optioned to Triple-A Pawtucket, and catcher Charles Johnson, who was immediately designated for assignment and released. As part of the trade, Colorado sent Boston $2.6 million to equalize the salaries.

Kim finished the season 5–9 with a 4.37 ERA as a starter. He filed for free agency on November 1, 2005 and re-signed with the Rockies. He earned $1.25 million in 2006 with a club option worth $2.5 million in 2007 (with a $250,000 buyout).

Kim briefly became a subject of talks between high-ranking U.S. and South Korean diplomats in August 2004. Upon his arrival in Seoul as the new U.S. Ambassador to Korea in August 2004, Christopher R. Hill spoke with his Korean diplomatic counterparts about Kim and the Red Sox, along with the U.S.–Korea relationship and other diplomatic and geopolitical issues surrounding the Korean peninsula. Ambassador Hill is one of the high-ranking "Red Sox fan" diplomats in the predominantly Red-Sox U.S. Department of State and watched the Red Sox win the World Series while stationed in Seoul.

Usually described as a submarine pitcher, Kim is a side-arm and under-arm hard thrower who uses a great variety of deliveries. Kim possesses a four-seam fastball with tailing movement frequently hitting the low 90s, a Frisbee slider with sweeping motion across the plate, an up-shoot slider with a rising motion, and a circle-changeup which he usually uses to strike out left-handed hitters. Nevertheless, during the three seasons between 2004 and 2006, his main problem had been the loss of right pitching balance which caused difficulty in ball control and reduced ball velocity. During that time, he also struggled against left-handed batsmen. In 2014, perennially award-winning third baseman Adrián Beltré named Kim as the toughest pitcher he had ever faced, due in large part to his pitching motion.

In 2002, Kim set a single-season franchise record for saves (36), breaking the old mark set by Gregg Olson in 1998 (30). Kim finished the season with an 8–3 record, 92 strikeouts, and a career-best 2.04 ERA in a team-high 72 appearances. On May 11, 2002, Kim struck out Scott Rolen, Mike Lieberthal, and Pat Burrell on nine pitches in the eighth inning of a ten-inning 6–5 win over the Philadelphia Phillies. Kim became the 23rd National League pitcher and the 32nd pitcher in Major League history to pitch an immaculate inning.

On June 12, 2002, Kim pitched two shut-out innings with four strikeouts and saved the Diamondbacks' 9–5 win over the New York Yankees at Yankee Stadium.

In 2002, Kim converted 36 of 42 save opportunities, eighth-best in the NL. Kim was selected for the All-Star Game.

Kim is remembered for his role in the 2001 World Series, in which he gave up consecutive ninth-inning leads in both Game 4 and Game 5, taking the loss in Game 4, though the Diamondbacks rebounded to win the Championship in 7 games over the New York Yankees. Kim went on to save 36 games for the Diamondbacks in 2002 and 16 for the Red Sox in 2003, and played in the 2002 All Star Game.

Arizona turned to Kim again as a closer after Mantei was lost to injury for the remaining 2001 season. Kim responded with 19 saves, a 2.94 ERA, and 113 strikeouts in 98 innings.

Kim later revealed in an interview how he felt during the 2001 World Series. "We went through the whole season, approximately 25 guys and then the coaching staff. That time it was like old people. They said, 'OK, we got last chance.'Some people said if we don't win, next year everybody's gone." Kim continued, "Then I gave up a home run. I didn't feel good. But we won."

In the 2000 season, Kim got the closer role when incumbent Matt Mantei opened the season on the disabled list. For the year, Kim struck out 111 hitters in just 70.2 innings pitched (14.14 per nine innings), including 11 out of 12 batters over five games, and twice struck out eight consecutive batters. After his 14 saves and a 1.82 ERA over his first 28 appearances, he was demoted to Triple-A Tucson at the end of July. Mostly used as a starter to restore his confidence, Kim returned to Arizona a month later. With Mantei reinserted as the closer, Kim pitched as a setup man and also started a game after recording 84 relief appearances.

Kim was signed by the Arizona Diamondbacks on February 19, 1999. Kim went 2–0 with 32 strikeouts in 21.1 innings in El Paso (AA) and then went to Tucson Sidewinders (AAA), where he posted 2–0 with 21 strikeouts in 17.1 innings. His ability to strike out batters caught the attention of Diamondbacks coaching staff. He was the youngest player in MLB at the time he debuted on May 29 at Shea Stadium. He came in to pitch in the bottom of the ninth inning, and after retiring Edgardo Alfonzo and John Olerud, struck out Mike Piazza and got the save in the Diamondbacks' 8–7 victory over the New York Mets.

Kim is a 1997 graduate of Gwangju Jaeil High School. Jae Seo and Hee-seop Choi were Kim's teammates in 1996 and they are very close friends. Named both the Most Valuable Player and Most Valuable Pitcher for the National High School championships in South Korea, Kim was selected to the 1996 National Junior Team, then named to the National Team in both 1997 and 1998. In that year, he pitched against the US Olympic team, striking out 15 batters in 6​⁄3 innings. Later, he helped Korea claim the gold medal in the Asian Games held in Bangkok, Thailand. Kim attended Sungkyunkwan University's Faculty of Law until 1999.

Byung-hyun Kim (Korean: 김병현 ; Hanja: 金炳賢 ; Korean pronunciation: [kimbjʌŋçʌn] or [kim] [pjʌŋçʌn] ; born January 19, 1979) is a South Korean former professional baseball pitcher. He had his most successful years with the Arizona Diamondbacks and the Boston Red Sox.

On August 8, Sunny Kim, another South Korean starting pitcher who had just joined the Rockies from the Washington Nationals, and Kim started doubleheader games at Coors Field against the Florida Marlins. They became the first two pitchers with same last name to start both ends of doubleheader since Gaylord and Jim Perry for the Cleveland Indians in 1974. The Rockies won both games and Kim collected a win.

On August 1, Kim collected his 50th career win with a career-high ten strikeouts in his starting matchup against Colorado Rockies' Josh Fogg.
