Carlos Martinez was up with the Cardinals earlier this season, appearing in seven games as a reliever before they sent the 21-year-old top prospect back to the minors to resume starting.
Martinez thrived at Triple-A, posting a 1.98 ERA in eight starts, and now the Cardinals have called him back up.
For now he seems likely to work out of the bullpen again, but Martinez is one of the best starter prospects in baseball–he cracked Baseball America‘s top 40 overall before the season and has upped his stock since then–so it’s only a matter of time before he joins the rotation.
The Rangers have signed catcher Jeff Mathis to a two-year contract, per Ken Rosenthal of The Athletic. The deal is pending a physical.
Mathis turns 36 years old at the end of March and has a career .564 OPS across 14 seasons, but he is well-regarded for his defense and ability to handle a pitching staff.
The arrival of Mathis could mean the Rangers are moving on from Robinson Chirinos behind the plate, as he is now a free agent. The Rangers could go after another catcher to complement Mathis or just have Isiah Kiner-Falefa back up Mathis. Though Kiner-Falefa mostly played elsewhere, including three spots across the infield, he did rack up over 300 defensive innings behind the plate in 2018.
