J. D. Martinez

On May 7, in a road game against the Baltimore Orioles, Martinez hit his 200th MLB career home run, having played in 957 MLB games. At the end of June, he had a .298 average with 18 home runs and 47 RBIs. Martinez was selected as a reserve designated hitter to the 2019 All-Star Game. For the season, Martinez batted .304 with 36 home runs and 105 RBIs. He had the highest batting average against left-handers of all major league batters with 100 or more at bats against them (.404). He had the lowest Soft Contact Percentage of all American League batters, at 10.2%. After the team's final game, when asked about possibly remaining with the Red Sox for another year, Martinez commented, "I don't mind moving around. I kind of like it."

He placed second in the American League in the 2018 season in home runs and batting average, and first in RBIs, and was a crucial component of the Red Sox's 2018 World Series title run.

On February 26, 2018, Martinez signed a five-year, $110 million contract with the Boston Red Sox. On April 7, Martinez hit his first home run in a Red Sox uniform at Fenway Park off Chaz Roe of the Tampa Bay Rays. Martinez won the AL Player of the Week Award for the week ending on May 20, after hitting five home runs, eight RBI, .346 average, and 1.414 OPS in seven games. At that point, he was tied with teammate Mookie Betts for the major league home run lead at 15, making them the first duo in Red Sox history to both hit at least 15 home runs within the first 50 games of the season. Batting .329 with 27 home runs and 73 RBIs, Martinez was named to the 2018 MLB All-Star Game as the American League's starting designated hitter. Spanning approximately one full season of play from the 2017 MLB All-Star Game to July 14, 2018, he led the major leagues in home runs (60), RBIs (152), and OPS (1.074). In a 19–12 win over the Baltimore Orioles on August 10, Martinez became the first player to reach 100 RBIs in the 2018 MLB season. Martinez again won the AL Player of the Week Award, for the week ending August 12, when he hit .464 with 11 RBIs and nine extra-base hits. He was also recognized as the AL Player of the Month for August, with a slash line of .373/.453/.686 with seven home runs and 25 RBIs in 26 games.

Martinez finished the 2018 season with 43 home runs and a career high 130 RBIs, which led MLB. He led the Red Sox in home runs, RBIs, and hits. In Game 1 of the ALDS, Martinez hit a three-run home run in the first inning off of New York starter J. A. Happ; Boston would win the game 5–4. In Game 5 of the ALCS, Martinez hit a solo home run off of Houston starter Justin Verlander; Boston won the game, 4–1, and clinched a berth in the World Series. In Game 5 of the World Series, Martinez hit a home run in the seventh inning to increase the Red Sox lead to 4–1. The Red Sox went on to win the game, capturing their ninth World Series title.

A native of Miami, Florida, Martinez was selected by the Astros in the 20th round with the 611th pick in the 2009 amateur draft from Nova Southeastern University (NSU). He is a three-time selection for the MLB All-Star Game and a three-time Silver Slugger Award winner, as well as the only player to earn the latter honor twice in the same season. On September 4, 2017, Martinez became the 18th player in MLB history to hit four home runs in a single game, doing so versus the Los Angeles Dodgers. He is of Cuban descent.

During a Spring Training game on March 18, 2017, Martinez left the game with an apparent foot injury. One week later, on March 25, further tests revealed that there was a lisfranc sprain in his right foot. As a result, Martinez began the season on the 10-day disabled list, with 3–4 weeks to recover. He rejoined the Tigers on May 12 after a four–game rehab stint with Toledo.

Martinez was awarded the AL Player of the Week award for the period ending May 21. Martinez batted .389 (7 for 18) with seven runs scored, four home runs, and nine RBIs while reaching base 17 times in six games to win his third career weekly honor. Martinez was awarded the AL Player of the Week award for the period ending July 16. Martinez batted .454 (5 for 11), with two runs scored, two home runs, and seven RBIs in three games to win his fourth career weekly honor. During the 2017 season with the Tigers, Martinez batted .305 with 16 home runs, 39 RBIs, and a 1.018 OPS. He hit .300 with 99 home runs, 285 RBIs, and a .912 OPS over four seasons with the Tigers.

On July 18, 2017, the Tigers traded Martinez to the Arizona Diamondbacks for Dawel Lugo, Sergio Alcántara, and Jose King. On September 4, Martinez hit four home runs versus the Los Angeles Dodgers to become the 18th major leaguer and first Diamondbacks player to hit four home runs in the same game. Each home run came in four consecutive at-bats against four different pitchers. As the Dodgers collectively obtained three hits, Martinez' achievement of four home runs made him the first with that distinction to realize more home runs than the opposing team had totals hits. He hit a home run in the seventh, eighth, and ninth innings, becoming the first player in the modern era to do so. He won the following NL Player of the Week Award—ending September 10—after batting .429, seven total home runs, and 11 RBI.

In 62 games with Arizona, Martinez hit .302 with 29 home runs and 65 RBIs. His combined achievements with Detroit and Arizona in 2017 included a .303 batting average in 119 games played and new career-highs in each of 45 home runs, 104 RBI, .376 OBP, and eight intentional walks. Other career highs of .690 slugging percentage and 9.6 at bats per home run also led the major leagues, albeit without gaining the requisite number of plate appearances to qualify for rate statistic titles in either of the American or National Leagues. He was second in the major leagues in OPS (1.066), third in home runs, fourth in OPS+ (166), and sixth in adjusted batting runs (41). After the season, Martinez became a free agent for the first time of his career.

On February 8, 2016, the Tigers signed Martinez to a two-year, $18.5 million contract extension.

On August 3 against the Chicago White Sox, in his first game after being activated from the disabled list, Martinez hit a pinch-hit game-winning solo home run off Chris Sale on the first pitch of the at-bat. Martinez played 120 games in the injury-shortened 2016 season, and hit .307 with 22 home runs and 68 RBI.

On January 16, 2015, Martinez and the Tigers avoided arbitration when the two parties agreed on a one-year, $3 million contract for the 2015 season.

On June 21, 2015, Martinez hit three home runs and had six RBIs in a game against the New York Yankees, becoming the first Tigers player to do so since Miguel Cabrera did it in May 2013.

Martinez was awarded the AL Player of the Week award for the period ending July 5, 2015. Martinez batted .458 (11 for 24) with six runs scored, four home runs, one double, and 10 RBIs in six games to win his second career weekly honor. He paced the Majors in slugging percentage (1.000) and total bases (24), and finished tied for first in home runs. Among AL leaders, he finished tied for first in on-base percentage (.500), second in RBI, third in batting average, tied for third in hits and tied for fourth in runs scored. On July 6, 2015, Martinez was named as a reserve for the American League at the 2015 All-Star Game.

On September 17, Martinez recorded his 40th home run of the season, doing so against the San Francisco Giants, and reaching the milestone for the first time in his career. He became just the fifth player to reach 40 home runs while playing for two different teams in one season. He was awarded the NL Player of the Week award for the period ending September 17, during which he batted .435 with three home runs, six RBIs, and eight runs scored over six games. He became the first NL player to win consecutive Player of the Week Awards since Bryce Harper in May 2015. It was Martinez' fourth weekly honor of 2017, making him the first player with four in the same season since the award was created in 1974. He hit his 16th home run of the month of September on September 28, tying Ralph Kiner in 1949 for the National League record for the month. Martinez was named NL Player of the Month for September, playing 24 games and hitting 18 home runs, .404 (40-for-99), eight doubles, 24 runs scored, and 36 RBIs.

After the 2013 season, Martinez began to make changes to his swing with the instruction of Robert Van Scoyoc and Craig Wallenbrock. On March 24, 2014, the Detroit Tigers signed Martinez to a minor-league contract. After he hit 10 home runs and drove in 22 runs over his first 17 games with the Triple-A Toledo Mud Hens, the Tigers purchased his contract, and he was called up and played his first game on April 21.

Martinez was awarded the American League (AL) Player of the Week Award for the period ending June 22, 2014. He batted .444 (12-for-27) with three doubles, four home runs (including one grand slam), 11 RBIs, and six runs scored in seven games to win his first career weekly honor.

He was named a finalist for the Players Choice Award for AL Comeback Player of the Year.

On October 3, during Game 2 of the American League Division Series (ALDS) against the Baltimore Orioles, Martinez became the first player in Tigers history—and just the 16th major leaguer—to hit a home run in each of his first two career postseason games. Martinez finished the postseason with one double, two home runs, and five RBI in three games as the Tigers were swept by the Orioles.

Since joining the Tigers in 2014 until the end of the 2017 season, Martínez hit the 10th-most home runs in baseball while taking the second-fewest plate appearances of the top 20 home runs hitters. His slugging percentage trailed only Mike Trout, and he ranked in the top five in wOBA and wRC+, while batting .300 and .362 OBP. His .690 slugging percentage in 2017 led all MLB hitters by 59 points before adding hitless plate appearances to qualify. In terms of quality of contact, Martinez led MLB with a 49% hard contact rate, and only Aaron Judge managed more barrels per plate appearance. Martinez ranked tenth with a 208-foot (63 m) average batted ball distance counting hitters who produced 250 or more batted ball events. He ranked 12th with a 90.8 miles per hour (146.1 km/h) average exit velocity, and sixth in fly balls with an average exit velocity of 97.2 miles per hour (156.4 km/h).

Martinez started his professional career with the Greeneville Astros of the Rookie-level Appalachian League, where he batted .403 before earning a promotion to the Tri-City ValleyCats of the Class A-Short Season New York–Penn League. He started the 2010 season with Lexington Legends of the Class A South Atlantic League (SAL) before earning a mid-season promotion to the Corpus Christi Hooks of the Class AA Texas League. He led SAL in each of batting (.362), on-base percentage (.433), and slugging percentage (.598). At the time of his promotion to the Texas League, he also led the SAL in hits, doubles, extra-base hits, runs scored and total bases. Martinez was honored as SAL Player of the Year, Most Valuable Player (MVP), and the Houston Astros' Minor League Player of the Year. He started the 2011 season with Corpus Christi before earning a promotion to the big leagues.

In July 2013, hitting coach John Mallee informed Martinez that he did not have the proper swing to become an impact hitter in the major leagues. The next month, he was in the trainer's room after spraining his left wrist, watching ESPN highlights of Ryan Braun batting, and realized his swing did not resemble Braun's. From there, Martinez began to study other top hitters including Albert Pujols and Miguel Cabrera and to investigate what modifications he could make to his swing to become a more successful hitter. He was outrighted off the Astros roster on November 20, 2013. After three years in an Astro uniform, he had hit .251 with 24 home runs amid progressively declining production. He was released by the team on March 22, 2014.

On April 13, 2012, Martinez hit the first ever home run in the new Marlins Park. With a runner on in the eighth, he hit an Edward Mujica offering into the Clevelander bar beyond the left-field wall for a game-tying home run. He led the club with 55 RBI in 2012.

On July 30, 2011, the Astros called up Martinez to replace Hunter Pence, whom they had traded to the Philadelphia Phillies. He became the first player drafted out of Nova Southeastern University to debut in Major League baseball. The following month, he drove in 28 runs, establishing an Astros rookie record for one month.

The Houston Astros selected Martinez in the 20th round of the 2009 Major League Baseball draft with the 611th overall selection. He was signed by Greg Brown, who is now the head coach at NSU.

Martinez attended Flanagan High School in Pembroke Pines, Florida, and graduated in 2006. The Minnesota Twins selected Martinez in the 36th round, with the 1,086th overall selection, of the 2006 Major League Baseball draft, but he did not sign with the Twins. Instead, he attended Nova Southeastern University (NSU), where he played college baseball for the Sharks from 2007 through 2009. He was a two-time All-Sunshine State Conference baseball player.
