Jonathan Singleton went 3-for-3 with two home runs for Double-A Corpus Christi on Thursday. Singleton has been crushing the ball since returning from suspension, batting .302/.406/.698 with five homers and 13 RBI over 15 games between Low- and Double-A. The 21-year-old could possibly push for a call-up this season and has a shot to be the Astros' starting first baseman in 2014.
