The Orioles are down 4-2 after Jackie Bradley Jr. drove in Will Middlebrooks with an RBI single with two outs in the sixth. Middlebrooks doubled for the only extra-base hit off Chen.

He's going to carry a 6.35 ERA into his next start in New York. He better use two hands.
There were lots of bloops and seeing-eye singles off Chen, but they all count the same.
