Wells earned the save in Friday's 3-2 win over the Astros, allowing one hit and one walk while striking out one batter in a scoreless ninth inning.
Wells continues to come through for the Orioles in the ninth with Ryan Helsley (elbow) on the injured list. The right-hander stranded two Astros baserunners, locking down his third save of the year. In 36 games, the 31-year-old now has a 2.96 ERA, 1.05 WHIP and 47:11 K:BB in 45.2 innings this season.
