Zachary Harrison Wheeler (born May 30, 1990) is an American professional baseball pitcher for the Philadelphia Phillies of Major League Baseball (MLB). He has previously played in MLB for the New York Mets.
Wheeler was born to a baseball-playing family in Smyrna, Georgia, but moved to Dallas, Georgia, shortly before starting high school. There, he pitched for East Paulding High School, leading the team to a state playoff appearance in 2009 and pitching a no-hitter against Mill Creek High School. The San Francisco Giants selected Wheeler sixth overall in the 2009 MLB draft, and he elected to sign with the team rather than honor his previous college baseball commitment for Kennesaw State. Wheeler played for the Giants' minor league teams in 2010 and 2011 before he was traded to the Mets in July 2011.
Wheeler then rose through the Mets' farm system, making his major league debut in 2013. Wheeler's development came to a sudden halt after he tore his ulnar collateral ligament during spring training in 2015. He underwent Tommy John surgery for the injury, and was expected to return during the 2016 season, but a series of setbacks during his rehabilitation kept Wheeler from returning to the mound until 2017.
Wheeler became a free agent at the end of the 2019 season and signed a five-year deal with the Phillies in December 2019. In his tenure with the Phillies, Wheeler has developed into the team's ace, posting a sub-3.00 ERA in five of his six seasons with the club and being named an All-Star in 2021, 2024, and 2025.
Zachary Harrison Wheeler was born on May 30, 1990, in Smyrna, Georgia, and was raised in Dallas, Georgia, by Barry and Elaine Wheeler. Wheeler's father played amateur baseball for 15 years, while his mother continued playing competitive softball even after having children, going so far as to placing a playpen in the dugout during weekend tournaments. Zack was the youngest of three brothers, all of whom grew up playing baseball. His oldest brother, Jacob, stopped playing sports in high school after undergoing a series of surgeries for supraventricular tachycardia, while his middle brother, Adam, was a minor league pitcher in the New York Yankees farm system until he suffered a torn glenoid labrum.
The Wheeler family moved to Dallas, Georgia, when Zack was 13 years old. Rather than attending Campbell High School like his brothers, Wheeler attended East Paulding High School, where he played baseball and basketball. As a junior in 2008, Wheeler posted an 8–3 win–loss record, with a 1.31 earned run average (ERA) and 127 strikeouts in 64+1⁄3 innings pitched, and was named the Georgia High School Association 4A Region Pitcher of the Year. The following season, he set a school record with 149 strikeouts in 76 innings, in addition to posting a 9–0 record and 0.54 ERA, and was named the Gatorade Georgia Player of the Year. As a designated hitter, Wheeler also had a batting average of .280 during his senior year. During the second round of 2009 Class 5A state playoffs, Wheeler pitched his first no-hitter, against Mill Creek High School. In 2015, East Paulding retired Wheeler's No. 45 jersey.
The San Francisco Giants of Major League Baseball (MLB) selected Wheeler in the first round, sixth overall, of the 2009 MLB draft. At the time, he had committed to playing college baseball at Kennesaw State. On August 17, 2009, however, Wheeler chose to sign with the Giants, a deal that included a $3.3 million signing bonus.
Wheeler was assigned to the Single-A Augusta GreenJackets of the South Atlantic League to start the 2010 season. He was placed on the disabled list early in the year with a fingernail injury on the middle finger of his throwing hand. After six weeks without play, Wheeler was sent to San Francisco to see the team's hand specialist. He later returned to the GreenJackets, making several relief appearances before re-entering the starting rotation. In 21 games with Augusta, including 13 starts, Wheeler posted a 3–3 record and a 3.99 ERA, with 70 strikeouts in 58+2⁄3 innings. He also made an appearance at the 2010 All-Star Futures Game in Anaheim, California.
Prior to the 2011 season, Baseball America named Wheeler the number two prospect in the Giants organization, and declared that he had the "best fastball" in the farm system. He was assigned to the High-A San Jose Giants, with whom he went 7–5 with a 3.99 ERA and 98 strikeouts in 16 starts and 88 innings pitched. He also appeared in the 2011 California League All-Star Game.
On July 28, 2011, the Giants traded Wheeler to the New York Mets in exchange for veteran outfielder Carlos Beltrán and cash. Giants general manager Brian Sabean said that they chose to trade Wheeler rather than a position player because, "[w]e didn't think (Zack) Wheeler was going to impact our situation in the immediate future. Quite frankly, it's our job to find another Wheeler or develop another Wheeler." He spent the remainder of the season with the Single-A St. Lucie Mets, where he went 2–2 with a 2.00 ERA and 31 strikeouts in 27 innings across six starts.
The Mets assigned Wheeler to the Double-A Binghamton Mets of the Eastern League at the start of the 2012 season, with the intention of allowing him to steadily progress through the farm system. He emerged as the star of that season's Binghamton pitching rotation, leading the Eastern League with a 25 percent strikeout rate. In 116 innings and 19 starts, Wheeler went 10–6 with Binghamton, giving up only two home runs in the process. In addition to being named an Eastern League All-Star, Wheeler received his second All-Star Future Game selection in 2012. On July 14, 2012, Wheeler pitched his first professional complete game shutout in a 1–0 victory over the Erie SeaWolves. The following day, the Mets clarified that, despite his pitching performance in Double-A, he was not being considered for a major league promotion, and that the rotation spot abdicated by Dillon Gee would be filled by either Matt Harvey or Miguel Batista.
The day after he struck out 11 batters in a game against the Harrisburg Senators, Wheeler was promoted to the Triple-A Buffalo Bisons on August 1, 2012. After a series of injuries befell members of the Mets' starting rotation, inning limits were placed on the team's top prospects, with Wheeler limited to 150. He was shut down on September 1, five innings into a match against the Lehigh Valley IronPigs. In 149 innings between Binghamton and Buffalo, Wheeler posted a 12–8 season record with a 3.26 ERA and led Minor League Baseball with 148 strikeouts. Mets general manager Sandy Alderson told reporters that Wheeler was expected to open the 2013 season with Buffalo and that he would likely make his major league debut that same year.
After the Bisons chose to reaffiliate with the Toronto Blue Jays during the 2012 offseason, Wheeler and other Mets Triple-A prospects began pitching in 2013 for the Las Vegas 51s of the Pacific Coast League, which was infamous at the time for its exceptional batting and, by extension, difficulty for pitchers. Wheeler stumbled at the beginning of the season, accumulating a 6.34 ERA in his first three starts with Las Vegas, but began to find his rhythm after striking out eight batters in 6+2⁄3 innings against the Reno Aces on April 30. With Las Vegas that season, Wheeler posted a 4–2 record with a 3.93 ERA and 73 strikeouts in 68+2⁄3 innings and 13 starts.
New York Mets (2013–2014, 2017–2019)
Wheeler made his major league debut on June 18, 2013, pitching six shutout innings in the second game of a doubleheader against the Atlanta Braves. Wheeler recorded seven strikeouts and gave up four hits in the 6–1 victory. Two months later, on August 15, Wheeler struck out a career-high 12 batters in a 4–1 win over the San Diego Padres. In doing so, he became the youngest Mets pitcher to record at least 12 strikeouts in a game since Doc Gooden in 1986. The Mets shut Wheeler down for the season on September 21, after he experienced shoulder stiffness in his final start. Wheeler finished his rookie season with a 7–5 record, a 3.42 ERA, and 84 strikeouts in 100 innings across 17 starts.
