Singleton went 4-for-4 with two home runs and three RBI during Thursday's loss to Triple-A Salt Lake.
Singleton, who had been hitting .139 prior to Thursday's game, raised his batting average 86 points with the four-hit performance. He's hitting .225 with three home runs and seven RBI through 11 games with Triple-A Fresno. The 24-year-old first baseman does not appear to be a threat to overtake Tyler White in Houston anytime soon, especially now that A.J. Reed has leapfrogged him on the organizational depth chart.
