Singleton is 10-for-37 (.270) with four doubles, two home runs and eight RBI through 10 games for Triple-A Fresno. Singleton has nine strikeouts (20.5 percent strikeout rate) but he's also drawn seven walks for a 15.9 percent walk rate. He's likely to earn a promotion to Houston at some point this season, especially if Chris Carter (.075/.159/.075) continues to struggle offensively for the Astros.
