Called up to help the Cardinals’ sagging bullpen four weeks ago, 21-year-old prospect Carlos Martinez is headed down to Triple-A after making seven appearances with a 4.50 ERA and 9/3 K/BB ratio in eight innings.
Martinez flashed the overpowering raw stuff that made him an elite prospect as a starter, averaging 96.0 miles per hour with his fastball, but it’s assumed that the Cardinals want him to continue starting at Triple-A.
He ranked as a top 50 prospect by both Baseball America and MLB.com going into the season, boasting a 2.74 ERA and 277 strikeouts in 250 innings spent entirely as a starter.
On Wednesday afternoon, the Tigers agreed to a one-year, $5.25 million with shortstop Jordy Mercer, per Fancred’s Jon Heyman.
Mercer, 32, hit .251/.315/.381 with six home runs and 39 RBI in 436 plate appearances for the Pirates last season. His triple-slash line from 2018 is pretty close to his career triple-slash line, so that’s about what the Tigers should expect from him.
Mercer will take over as the full-time shortstop for the Tigers, who lost José Iglesias to free agency. Mercer does have versatility, with the ability to play first, second, and third base as well as the corner outfield in a pinch.
