In a recent analysis, I recommended Cosart as a pickup for owners in deeper leagues. Clearly, there isn't as much urgency now, but he is still worth stashing in AL-only leagues, if not in deeper mixed league formats. The 22-year-old remains on a roll, getting 10 strikeouts over 5 2/3 scoreless innings in his most recent start. When the Astros feel that Cosart is ready, they shouldn't have any problem finding room for him in their beleaguered rotation.

The Astros have a bevy of rotation options, including Paul Clemens, Dallas Keuchel, Travis Blackley and Jose Cisnero, currently in long relief roles, but none should be a major roadblock for Cosart. After pitching to contact in the lower levels of the minors, Cosart has been getting whiffs since getting promoted to Triple-A last year.

Once Cosart gets the call, there will likely be a rush to pick him up, especially in deeper leagues. Get Cosart now and stash him, while he is still available in 95 percent of the leagues on CBSSports.com.

Houston's best possibility to replace Peacock comes in Jordan Lyles, who would be on normal rest for Thursday if called up. He is 2-2 with a 5.32 ERA over six games and five starts at Triple-A Oklahoma City. 

Jarred Cosart is another option. He has better numbers than Lyles. He is 2-0 with a 2.86 ERA over five appearances and four starts with the RedHawks, including 23 Ks over 22 innings. 

The last options could come from the bullpen in long men Paul Clemens or Jose Cisnero. Through 25 games, the Astros' starters have the highest ERA in the majors at 6.34 and have pitched the fewest number of innings per start at 4.6. 

Cosart hasn't allowed more than one run in any of his four outings, yielding two runs on 10 hits and five walks in 17 2/3 innings. He also has 21 strikeouts.
