The Chicago Cubs' bullpen catcher was seen celebrating the team's World Series berth in a Speedo. FS1

Chicago Cubs bullpen catcher Chad Noble made his mark on the MLB postseason with a celebration to remember.

After the Cubs clinched their first berth into the World Series since 1945, Noble was seen celebrating around the clubhouse in a Speedo.

Noble then boldly took his underwear act onto the field at Wrigley for some shirtless celebrating.

Noble was a 37th-round pick by the Cubs in 2010 and has been the team's bullpen catcher since 2014.

If this is what he did when the team clinched a World Series berth, imagine what he'll do if they win it all.
