Baltimore Orioles manager Buck Showalter responded to Boston Red Sox pitcher John Lackey's loud "no comment" on slugger Nelson Cruz after Saturday night's game, telling ESPN Radio on Sunday that "everybody needs to make sure that their own backyard is clean" when it comes to performance-enhancing drugs.

Cruz went 5-for-5 Saturday night in the second game of a doubleheader, helping the Orioles beat Lackey and the Red Sox to gain a split of the two games. Cruz had three of his hits off Lackey, including a home run, single and double.

After the game, when asked to comment on Cruz's big game, Lackey made a not-so-veiled comment on the Orioles slugger's past suspension for PEDs.

"I'm not going to comment on him," Lackey said. "I've got nothing to say about him. There are some things I'd like to say, but I'm not going to. You guys forget pretty conveniently about stuff."
