Astros Fielding Interest In Cosart, Not Shopping Keuchel

12:03pm: The Marlins and Rangers are two teams that are checking in on Cosart, Rosenthal reports (Twitter links).

9:59am: The Astros are “very busy” taking calls on righty Jarred Cosart, tweets Ken Rosenthal of FOX Sports. Houston has taken lefty Dallas Keuchel off the market, however, though it always seemed a longshot for him to be dealt.

Houston has been said to be willing to listen on its young starting pitching, which has featured some better-than-expected performances. Of course, the biggest surprises have comes from Keuchel and Collin McHugh. Unsurprisingly, the Astros appear more hesitant to deal either of those arms.

But Cosart, 24, has turned in a solid season in his own right. He owns a 4.41 ERA through 116 1/3 frames with 5.8 K/9 against 3.9 BB/9 and a sterling 56.5% groundball rate. That has been good for a 4.02 FIP, 4.28 xFIP, and 4.42 SIERA — hardly ace-level numbers, to be sure, but useful and promising enough given his age. Of course, much of Cosart’s value lies in the fact that he will not even be eligible for arbitration until 2017.
