Teng will start Sunday's game against the Reds, Matt Kawahara of the Houston Chronicle reports.
Teng has largely worked out of the bullpen for Houston this season, accruing a 2.35 ERA and 0.96 WHIP with a 22:7 K:BB through 23 innings in 14 appearances (one start). Though he'll be drawing a start in the series finale in Cincinnati, Teng hasn't recorded more than nine outs in an appearance yet this season, so he'll likely remain in Sunday's contest for a handful of innings before turning things over to the bullpen. Cody Bolton could be a candidate to cover multiple frames in relief behind Teng.
