Cincinnati Reds 2010 Leake was drafted out of high school in
2006 by the
Oakland Athletics in the seventh round (218th overall), but chose instead to attend college. The
Cincinnati Reds re-drafted him eighth overall in the
2009 draft, which Leake accepted. He received a $2.3 million signing bonus and was signed to a $400,000 contract. He played for the
Peoria Saguaros in the
Arizona Fall League, winning the
Arizona Fall League Rising Star Award. In 2010, Leake competed for the Reds' fifth starter spot and ultimately won a spot on the Reds' twenty-five man roster amid competition from veterans
Mike Lincoln,
Justin Lehr, and
Micah Owings and young pitchers
Travis Wood and
Aroldis Chapman. Leake's contract was purchased on April 11, 2010. To make room for him, the
Reds optioned
Juan Francisco to the
Louisville Bats, the Reds'
Triple-A affiliate. They also designated
Pedro Viola for assignment. Leake became the first player since
Xavier Nady, when he was with the
San Diego Padres in 2000, to go directly from the draft to the major leagues, and was the first starting pitcher to accomplish the feat since left-hander
Jim Abbott of the
California Angels in 1989. He also was the first Cincinnati Red to do so since the abolition of the
Bonus Rule after the
1965 season (shortstop
Bobby Henrich, pitcher
Jay Hook, and catcher
Don Pavletich, who did so in 1957, all were "Bonus Babies"). On May 15, 2010, Leake earned his fourth career win. With a career record of 4–0 at that point, he became the first
Reds rookie starting pitcher to open 4–0 since
Pat Zachry and
Santo Alcalá did so in 1976. Leake became the first rookie pitcher in Reds' history to remain undefeated after his 10th start by throwing six innings of shutout ball on May 30, 2010, against the
Houston Astros. On June 5, 2010, against the
Washington Nationals, Leake earned his fifth victory. With this win, Leake moved to 5–0 in his career and joined
Santo Alcalá as the only rookies in Reds history to begin their careers with that record. Leake did throw a bullpen session late in the month, but was determined to be not ready for pitching in the post season and effectively "shut down" once again. He did see action as a pinch-runner and pinch-hitter in the month after showing his hitting ability during the season.
2011 Entering spring training, Leake was considered the sixth man in the rotation, and faced starting the season in the minor leagues. However,
Johnny Cueto and
Homer Bailey both went on the DL, and Leake made the rotation out of spring. He won his first two decisions, posting a 5.40 ERA. Leake was optioned to triple-A for the first time in his career on May 14 to make room for reliever
José Arredondo to come off the DL. Arredondo's rehab assignment had reached the maximum 30 days, he had pitched well, and was out of options. Leake was called back up on May 28 and started against the Braves, earning the win and pitching six innings of one-run ball.
2012 On May 21, 2012, Leake hit the first
home run of his career, off
Mike Minor of the
Atlanta Braves in the fourth inning of a game at
Great American Ball Park. On June 29, 2012, Leake threw his first complete game against the
San Francisco Giants in a 5–1 victory. Leake made his first postseason appearance in the 4th game of the
NLDS against the San Francisco Giants. Leake surrendered a leadoff home run to the first batter of the game,
Ángel Pagán. The Giants would go on to win by a final of 8–3.
2013–2015 In 2013, Leake started 31 games, going 14–7 with a 3.37 ERA and 122 strikeouts over innings. He started 33 games in 2014, going 11–13 with a 3.70 ERA and 164 strikeouts over innings. Leake began the 2015 season as the Reds #2 starter. In 21 starts for the Reds, Leake went 9–5 with a 3.56 ERA.
San Francisco Giants On July 30, 2015, Leake was traded to the
San Francisco Giants in exchange for pitching prospect
Keury Mella and minor league third baseman
Adam Duvall. Leake was scratched from his second scheduled start with the Giants due to a
strained hamstring and was placed on the disabled list. On August 22 he was activated from the 15-day disabled list. Leake produced mostly disappointing results for the Giants. He was able to pitch at least six innings in seven of his nine starts but only able to win two of the nine games while posting a 4.07
earned run average.
St. Louis Cardinals On December 22, 2015, Leake signed a five-year, $80 million contract with the
St. Louis Cardinals. He was given
jersey number 8, the same number he wore while playing for Arizona State.
2016 He made his Cardinals debut on April 6 against the
Pittsburgh Pirates, allowing four runs and seven hits in IP, resulting in being charged with the loss as Pittsburgh won, 5–1. He earned his first win a Cardinals uniform on May 10 against the
Los Angeles Angels of Anaheim in an 8–1 advantage. In consecutive starts against the
Milwaukee Brewers and
San Diego Padres on July 10 and 18, he struck out at least ten batters in consecutive games for the first time in his career, after previously having two total ten-strikeout games in 189 starts. Covering his previous innings, he had struck out 45 batters while walking three. Overall, Leake struggled in his first season as a Cardinal, posting an ERA of 4.69, his highest ERA of his career. He finished 9–12 in 30 starts. He had the lowest
left on base percentage of all major league pitchers, stranding only 65.6% of base runners.
2017 At the start of the season, Leake was 5–2 with a 1.91 ERA in 9 starts. From May 29 to August 26, Leake went 2–10. For the season with St. Louis, Leake finished 7–12 with a 4.21 ERA in 26 starts.
Seattle Mariners 2017 On August 30, 2017, the Cardinals traded Leake and international signing bonus space to the
Seattle Mariners for Rayder Ascanio. He made his Mariners debut on September 1 against the
Oakland Athletics, allowing only two earned runs on eight hits and a walk over seven innings to pick up his first win as a Mariner. In five starts with the Mariners, he finished strong with a 3–1 record with 2.53 ERA, 27 strikeouts, and 2 walks in 32 innings pitched.
2018 Leake started 31 games for the Mariners, finishing with a record of 10–10 with a 4.36 ERA in innings. On May 4 against the
Los Angeles Angels, Leake allowed
Albert Pujols' 3,000th career hit. He had the fewest strikeouts per 9 innings in the major leagues (5.77), and he also led major league pitchers in highest contact percentage (84.8%) of batters against him. In addition, he led major league pitchers in percent of balls
pulled against him (47.8%). Twelve batters reached base against him on an error, tops in the major leagues.
2019 On July 19, against the Angels, Leake took a
perfect game through eight innings until allowing a leadoff hit by
Luis Rengifo. He subsequently walked
Kevan Smith, but got the next three batters out, held the shutout, and the Mariners won 10–0. Leake closed his 2019 season with the Mariners having started 22 games, resulting in a 9–8 record and 4.27 ERA. He had two complete games and had a career-best 1.2 BB/9 during his 137 innings prior to being traded to the Diamondbacks.
Arizona Diamondbacks 2019 On July 31, 2019, Leake was traded to the
Arizona Diamondbacks in exchange for
José Caballero. Between the two teams, he led all major league pitchers in home runs allowed, with 41, and in hits, with 227.
2020 On June 29, 2020, Leake became the first player in MLB to announce he would not participate in the shortened
2020 season during the
COVID-19 pandemic. Leake's agent,
Dan Horwits, stated the decision was "not easy" for Leake and that he expected to play in 2021. On October 28, 2020, the Diamondbacks declined an $18 million option on Leake's contract for the season, instead paying him a $5 million
buyout, and he was declared a free agent. ==Personal life==
