After a professional career that spanned 17 years, veteran right-hander Jay Jackson is hanging up his glove. Robert Murray of FanSided reported this afternoon that Jackson is retiring from his playing career, adding that the 37-year-old hopes to have a second act in baseball, whether that comes by working for a team or in broadcasting.
Jackson was selected by the Cubs in the ninth-round of the 2008 MLB draft and made his pro debut later the summer at 20 years old. A fringe top-100 prospect entering the 2010 season after he pitched to a 2.98 ERA in 24 starts across three levels of the Chicago farm system, Jackson spent the next three seasons struggling at the Triple-A level without breaking into the majors. He was eventually released by the Cubs in early 2013 and bounced between the Marlins, Pirates, and Brewers before eventually landing with the Padres prior to the 2015 season. In San Diego, the right-hander moved to a full-time bullpen role and dominated the Double- and Triple-A levels, earning the opportunity to pitch in the majors for the first time in his career.
Jackson’s first big league cup of coffee did not go especially well, as he surrendered three runs in 4 1/3 innings across six appearances. Even so, the opportunity was enough to get the righty noticed by the Hiroshima Carp of Japan’s Nippon Professional Baseball. He pitched for the Carp for three seasons, from 2016 to 2018, and put together an impressive resume with a sterling 2.11 ERA and a 26.9% strikeout rate in 175 NPB innings. That work earned him his second big league opportunity, as he returned to the Brewers organization and pitched to a 4.45 ERA across 30 1/3 innings of work in 2019, but it was only after a second sojourn to Japan (this time as a member of the Chiba Lotte Marines) in 2020 that Jackson was able to stick in the majors.
After signing with the Giants in 2021 for his age-33 season, Jackson enjoyed a late-career stretch of success in the majors. Though he pitched just 52 2/3 innings at the big league level for San Francisco, Atlanta, and Toronto from 2021 to 2023, Jackson posted an excellent 2.73 ERA across those 50 appearances and struck out 26.5% of his opponents. That was enough to earn Jackson a look from the Twins last year in his age-36 season, though he struggled badly with a 7.52 ERA across 20 appearances before being released by Minnesota last year. Jackson initially signed with the Mexican League’s Bravos de Leon earlier this month in an effort to continue his playing career, but evidently has now decided to wrap up his days as a player instead.
Overall, Jackson pitched to a lifetime 4.43 ERA (97 ERA+) with a 4.47 FIP across 113 2/3 major league innings, with a 7-4 record and 136 strikeouts in 104 career games. That’s in addition to his excellent years in Japan, where he posted a 2.16 ERA and struck out 204 batters in 183 NPB innings. We at MLB Trade Rumors congratulate Jackson on his nearly two decades of work in baseball and wish him all the best in whatever comes next.
