Jarred Cosart has struggled with his control at Triple-A, walking 50 batters in 93 innings, but the Astros have decided that the 23-year-old right-hander is ready for the majors and he’ll make his debut tomorrow against the Rays.
Cosart was acquired from the Phillies as part of the haul for Hunter Pence in 2011 and MLB.com ranked him as the No. 89 prospect coming into the season. Aside from the spotty control he’s pitched very well at Triple-A with a 3.29 ERA and 93 strikeouts in 93 innings, holding opponents to a .213 batting average.
Cosart has electric raw stuff, throwing a heavy mid-90s fastball that generates tons of ground balls and very few homers. He hasn’t fared particularly well of late, allowing five runs and four walks in his final Triple-A start last week, and the Rays are a relatively tough debut matchup with the fifth-best offense in the league.
The Mariners have signed reliever Mark Lowe, ESPN’s Jerry Crasnick reports. The Tigers released him on Sunday.
Lowe, 33, is entering the last of a two-year, $11 million deal signed with the Tigers in December 2015. The right-hander struggled to a 7.11 ERA with a 49/21 K/BB ratio in 49 1/3 innings last season. His performance this spring didn’t do much to inspire confidence.
Lowe began his major league career with the Mariners, breaking out in 2009 with a 3.26 ERA across 80 innings. He has been inconsistent throughout most of his 11-year big league career, however.
The Cardinals announced on Thursday that pitcher Trevor Rosenthal has been placed on the 10-day disabled list with a right lat strain. Sam Tuivailala has been added to the roster in Rosenthal’s place.
The Cardinals’ closer until the second half last year, Rosenthal came into camp this spring hoping to battle for a rotation spot. However, the lat injury killed that dream. When Rosenthal is healthy, he’ll return to the bullpen.
Last season, Rosenthal posted a 4.46 ERA with 14 saves and a 56/29 K/BB ratio in 40 1/3 innings.
