Thomas Hatch Signs With KBO’s Doosan Bears

The Korea Baseball Organization’s Doosan Bears have signed right-hander Thomas Hatch, per a team announcement (h/t to Dan Kurtz of MyKBO). The 30-year-old will earn $1MM in 2025, paid out as a $200K signing bonus and an $800K salary.

A third-round pick by the Cubs in the 2016 draft, Hatch was shipped to Toronto in the 2019 trade that brought right-hander David Phelps to Chicago. Hatch subsequently made his big league debut with the Blue Jays just a year later during the shortened 2020 season and impressed in his first taste of big league action with a 2.73 ERA in 26 1/3 innings of work. Solid as that top-level run prevention figure was, however, there were some potential red flags under the hood including an 11.9% walk rate and a rather pedestrian 4.14 FIP.

Given those concerning peripherals, it wasn’t necessarily a shock when the wheels came off for Hatch a bit during the 2021 season. The right-hander pitched just 14 innings in the majors with a 10.93 ERA over the next two years as he walked eight batters and struck out 12. In spite of those struggles, he continued to post decent numbers with Triple-A Buffalo and earned a more extensive opportunity in the majors during the 2023 season. It went reasonably well for the right-hander, as he posted a solid 4.08 ERA across 28 2/3 innings of work with the Blue Jays and Pirates. Looking under the hood, Hatch’s performance came with a strong 52.3% groundball rate and a respectable 20.2% strikeout rate while his walk rate dipped to a still elevated but more manageable 9.3%.

Those promising peripherals and improved results got the attention of the Hiroshima Carp of Japan’s Nippon Professional Baseball, who signed him to a one-year deal last offseason. That first foray into overseas baseball didn’t go especially well for Hatch, as he was relegated to the Carp’s Western League affiliate for most of the season after struggling with the Central League club. While he dominated in 72 1/3 Western League innings to the tune of a 2.36 ERA, Hatch was torched in the Central League with a 7.36 ERA in 22 innings across five appearances. Those struggles were evidently enough for Hiroshima to part ways with Hatch this winter, leading him to head to South Korea to sign with the Bears. In the KBO, Hatch will lock down a larger salary than he would’ve been able to find in stateside ball and hope to re-establish himself as a pitcher, potentially opening the door to a more lucrative return to either NPB or MLB play in the future.
