After reviewing Monday's fiery argument between Joe Girardi and Orioles manager Buck Showalter Major League Baseball has determined that neither skipper will face discipline for the flap.

Showalter was enraged when he saw Girardi chirping at Baltimore third-base coach Bobby Dickerson in the first inning of Monday's series opener at Camden Yards. Girardi suspected the Orioles of stealing signs.

After the inning Showalter came charging out of the O's dugout and made a throat-slash gesture while also telling Girardi to talk to him not his third-base coach. Umpires got in front of both Showalter and Girardi and players from both sides came out of the dugouts too. Umps also warned both teams.

Girardi hasn't said much about the incident since. "It was something that I saw" Girardi said after Monday's game. "I'm going to leave it at that."
