KBO’s Kia Tigers To Sign Adam Oller

Right-hander Adam Oller has agreed to terms with the Kia Tigers of the Korea Baseball Organization, reports Ari Alexander of Houston’s KPRC-2. It’ll be the Gaeta Sports Management client’s first stint overseas, and he’ll join the reigning KBO champs.

Oller, 30, has pitched in each of the past three big league seasons. Originally a 2016 draftee of the Pirates, he wound up out of affiliated ball by 2019 but parlayed stints in the independent Frontier League (2019) and in the Australian Baseball League (2020-21) into a minor league opportunity with the Mets. He made the most of that, pitching his way into prospect status with an outstanding age-26 season split between Double-A and Triple-A. The A’s were intrigued enough to acquire Oller and fellow righty J.T. Ginn as their return from the Mets in the trade sending Chris Bassitt to Queens.

Things didn’t work out for Oller in Oakland, however. He was in the majors early during his first season with the organization but hit hard in both 2022 and 2023, yielding a combined 7.09 ERA in 94 frames. The A’s tried to pass him through waivers in July of ’23, but the Mariners claimed him and optioned him to Triple-A Tacoma. He’d spend the remainder of the season with Seattle’s top affiliate, eventually clearing waivers and electing free agency after being dropped from the roster in October.

Oller caught on with the Guardians and Marlins on minor league deals in the year that followed, the latter of whom selected him to the majors this past July. He pitched another 42 1/3 MLB frames across eight starts but was tagged for a 5.31 ERA. Oller did have a handful of nice outings in Miami, but it was an up-and-down tenure with more lows than highs. He was passed through waivers again at the beginning of this month, elected free agency and will quickly find a new opportunity overseas.

Despite his lack of MLB success, there’s reason to think Oller could fare well in the KBO. He posted sharp numbers in Triple-A in 2021-22, struggled through a disastrous season with the Athletics’ Triple-A Vegas club in 2023, and then again pitched to a 2.88 ERA with the Marlins’ top affiliate this past season. His 6.22 Triple-A ERA in 2023 skews his career-long mark to 5.01, but he’s typically been a solid arm at the top minor league level. Oller averages 93.7 mph on his four-seamer, complementing the pitch with a curveball and lesser-used changeup.

It’s at least feasible that Oller could spin one strong KBO season into a big league return, though success overseas can also open further opportunities in Asia. It’s common for players who thrive in the KBO to re-sign for a pay raise in their second season or perhaps to draw interest from teams in Japan’s Nippon Professional Baseball. However it plays out, the earning power for Oller overseas is surely greater than it would be on a minor league deal in North America, and for a pitcher who’s already turned 30 and is still not into arbitration, that’s a compelling selling point.
