Teng entered the game in the fifth after Ronel Blanco tossed four scoreless innings and immediately ran into trouble. He hit Sam Antonacci with a pitch and walked Miguel Vargas before Andrew Benintendi broke the scoreless tie with an RBI single. Colson Montgomery followed with a two-run double, leaving Teng responsible for all three runs in the inning. While the right-hander recovered to work a scoreless sixth, he would end up getting tagged with the loss while seeing his ERA rise to 4.66. He's given up multiple earned runs in seven of his last 11 relief appearances dating back to the beginning of June.

Teng was optioned to Sugar Land in late July and worked exclusively out of the bullpen while with the minor-league club, turning in a 3.48 ERA, 0.97 WHIP and 15:3 K:BB across 10.1 innings. He'll work in relief for the Astros after making 10 starts for the team earlier this season.
