The Marlins announced that they’ve designated right-hander Kyle Keller for assignment. His spot on the 40-man roster goes to right-hander Yimi Garcia, whose previously reported one-year contract with Miami is now official.
Keller, 26, was selected to the 40-man roster in advance of the 2018 Rule 5 Draft. At the time, he had just wrapped up an impressive 2018 season in which he logged 52 2/3 innings of 3.08 ERA ball across three minor league levels, averaging 13.3 K/9 and 3.6 BB/9 along the way.
The 2019 season, though, wasn’t as successful. Keller tallied 54 innings of relief in Triple-A and maintained a strong strikeout rate (12.2 K/9), but his results didn’t match up to his 2018 output, due largely to an inability to strand runners (63.2 percent). Keller logged a 4.50 ERA in Triple-A and made his MLB debut late in the year, allowing four runs in 10 2/3 innings (3.38 ERA). But Keller also allowed three home runs in that brief time in addition to eight walks and two hit batsmen.
The Marlins will have a week to trade Keller or run him through outright waivers in hopes of keeping him in the organization.
