Former MLB pitcher drawing interest after stellar season in Japan

Right-hander Kyle Keller is reportedly drawing interest from six major league teams, per Robert Murray of FanSided. Murray adds that Keller, who pitched in Japan the past two seasons, is also drawing interest from NPB clubs.

Keller, 30, was an 18th-round pick by the Marlins in the 2015 draft and pitched in the majors for parts of three seasons, from 2019-21. He recorded 46 1/3 innings of work across the Marlins, Angels and Pirates organizations during that time, struggling to a 5.83 ERA with a 7.00 FIP. Control problems were the main culprit of Keller’s struggles, as evidenced by his 15% walk rate in the majors. Entering the 2022 campaign, Keller signed on with NPB’s Hanshin Tigers to become the club’s closer.

The righty impressed in that role over two seasons with the Tigers. After posting a strong 2.72 ERA in 49 2/3 innings of work in Japan during the 2022 season, Keller put together an even more impressive season in 2023, with a sterling 1.71 ERA across 26 1/3 frames. He struck out 23.7% of batters faced on the year and has even managed to rein in his control issues during his time overseas, walking just 8.8% of batters faced over the past two seasons.

Given those strong numbers during his time in Japan, it’s easy to see why MLB clubs would have interest in Keller for the 2024 campaign. While a reliever on the wrong side of thirty with a fairly limited NPB track record and previous struggles at the major league level is unlikely to land a significant multi-year deal in the majors, it’s certainly feasible that Keller could find a team willing to roll the dice on a major league contract for his services. Free agent lefty Matt Moore and Diamondbacks right-hander Scott McGough are among the examples of big leaguers who departed MLB for the NPB before returning stateside in recent years.
