UNDATED (AP) — Cincinnati Reds closer Aroldis Chapman was in top form as he made his season debut Sunday afternoon.

Chapman struck out the side in a hitless ninth inning to close out the Reds' 4-1 triumph over Colorado. His first four pitches were clocked at 100 mph, and he fanned Nolan Arenado with a 102-mph before hitting 101 mph on his final four throws.

The flame-throwing lefty was on the mound less than two months after being struck above the left eye by a line drive during a spring training camp.

Todd Frazier hit a solo homer and Skip Schumacher had two RBIs to support Homer Bailey, who gave up Charlie Blackmon's home run and just three other hits over 7 1/3 innings.
