As stated in this blog yesterday, Mark Melancon was the pickup to get saves for the Astros and it was made official today. The Astros placed Brandon Lyon on the 15-day disabled list with a partially torn rotator cuff. He doesn't need surgery.
Melancon has appeared in 18 games and pitched 15 2/3 innings, allowing 14 hits with 12 strikeouts and six walks. He has a 1.72 ERA and a 1.28 WHIP and has a 65 percent groundball rate. Melancon should be owned in all leagues.
