Both New York Yankees manager Joe Girardi and Baltimore Orioles manager Buck Showalter had to be restrained Monday night after the first inning of the teams' game in Baltimore.

It was unclear immediately what spurred the confrontation between the managers, but Girardi and Showalter caused both benches amid back-and-forth shouting.

It started after the end of the first inning, when the Orioles tied the game at 1-1. After the inning, Showalter came running out of the dugout in an apparent fury at Girardi, appearing to mouth, "That's not right, Joe!" and multiple obscenities. He needed to be restrained by home plate umpire Ed Hickox. Girardi, who was initially much more calm, came rushing out of the dugout and had to be held back by multiple Yankees, including bench coach Tony Pena.

MASN's Rich Kubatko relays one theory of why the near-dustup occurred:

One theory being floated here is Girardi said something to third base coach Bobby Dickerson, who relayed the message to Showalter, which led to the heated exchange.

Both the Yankees and Orioles are in the middle of a five-team battle for the second American League Wild Card spot. Baltimore led the Yankees by a half-game headed into the teams' three-game series in Baltimore.
