Koby Clemens

On February 13, 2015, Clemens was hired as a minor league spring instructor for the Astros farm system. Astros Director of Player Development Quentin McCracken said the Astros "expect by the end of the year or by next season he will be on staff fully." He now owns his own baseball company called Koby Clemens Baseball Clinics and teaches individual and private lessons.

Koby played in the California Winter League in Palm Springs, California from January 18 to February 16, 2013. From 2012-2014 he played for the Sugar Land Skeeters, including a game when he caught pitches thrown by his father.

On February 9, 2012, Clemens signed a minor league contract with the Toronto Blue Jays. During the 2012 season, he played for the Blue Jays' Double-A affiliate, the New Hampshire Fisher Cats of the Eastern League, and their high Single-A team, the Dunedin Blue Jays of the Florida State League as a catcher, first baseman, third baseman, outfielder, and designated hitter. He was released at the end of the season.

In 2011, Koby was with the Houston Astros' Triple-A affiliate, the Oklahoma City RedHawks of the Pacific Coast League, as their first baseman.

Clemens started playing at the Puerto Rico Baseball League with the Mayagüez Indians as a first baseman in the fall of 2011. However, he abandoned the team abruptly on November 10, 2011. There were rumors his father, former MLB pitcher Roger Clemens, persuaded him to leave the island because of the kidnapping of Washington Nationals catcher, Wilson Ramos in Venezuela the day before. For abandoning the team with no reason given, Koby was banned from playing baseball in the Caribbean Baseball Confederation.

In 2010, he again played for Corpus Christi, then played with the Peoria Javelinas in the Arizona Fall League.

He converted to play as a catcher and played for the Corpus Christi Hooks in the Double-A Texas League. As of June 12, 2009, he returned to play with the Lancaster JetHawks in Advanced A in the California League in the roles of a catcher and designated hitter.

In 2008 he played with the Single-A Salem Avalanche in the Carolina League, batting .268.

In 2007 he returned to the Single-A Lexington Legends, where he batted .252 with 15 home runs and 56 RBIs in 115 games.

In 2006, he played with the Single-A Lexington Legends of the South Atlantic League, where he batted .229 with 5 home runs and 39 RBIs in 91 games. Clemens' sole appearance as a pitcher in professional baseball was for the Legends in 2006. On June 25, 2006, Clemens was in the news in a game against the Asheville Tourists. He was declared safe in a controversial play on second, leading the Tourists manager Joe Mikulik to go on a rampage. Through 2006, in the minors he batted .249 with 9 home runs, 63 RBIs, 7 stolen bases (while being caught once), and a .385 slugging percentage in 449 at bats. That season he hit a home run off his 43-year-old father, Roger Clemens, in a minor league exhibition game. In Koby's next at bat, Roger threw a brushback pitch at Koby in retaliation. They also played a game together in 2006,when the elder Clemens was making his comeback with the Astros and pitched a game for Lexington.

In the 2006 Hawaiian Winter League, playing for North Shore Honu, Clemens batted .196 with 1 home run and 9 RBIs in 32 games.

In 2005, he played his first minor league baseball season, hitting .297 with 4 homers and 17 RBIs in 33 games for the Rookie League Greeneville Astros, and .281 with 6 RBIs in 9 games with the Class A Tri-City ValleyCats. He committed 15 errors in 32 games at third base.

He hit .413 as a junior, with 4 home runs and 23 RBIs in 2004. He had a .519 batting average and was named all-state in his senior year. As a pitcher, he had a 7–1 record and a 1.75 ERA.

He signed with the University of Texas at Austin (where his father played) to play first base on November 17, 2004, but never attended, choosing to go straight to professional baseball after he was drafted by the Houston Astros.

Koby Aaron Clemens (born December 4, 1986) is an American former professional baseball infielder and outfielder and current coach for the Houston Astros farm system. He is the eldest son of former Major League Baseball pitcher Roger Clemens.

Born on December 4, 1986, in Houston, Texas, he was a two-sport star at Memorial High School, splitting time between football and baseball, before he suffered a back injury ending his brief football career.
