Reds closer Aroldis Chapman put the tying runs on base Tuesday, but worked out of the jam to close out a 4-2 win over the Cubs.

Chapman allowed a leadoff single to Junior Lake, and then put the tying run on base in the form of Mike Olt, who walked. He struck out Ryan Sweeney to end the threat, however, his second strikeout of the inning.

Chapman is now 18 for 20 in save opportunities for the season, and he lowered his ERA to 2.45 in 25 2/3 innings.
