Aroldis Chapman has been virtually untouchable in his relief outings this season, including another lights-out show to help beat St. Louis on Wednesday.

Left-hander Chapman (2-0) earned the win with two scoreless innings. The fan favorite "Cuban Missile" reached the upper 90s per usual with his fastball, allowed one hit, struck out five and walked none.

Chapman this year is unscored upon in five innings, has allowed only two hits and struck out 10. He has not walked a batter after struggling with control last year (50 innings, 41 walks).

"Eventually he'll be a starter but right now, where would we be without him in the bullpen?" Reds manager Dusty Baker said.
