After helping the Boston Red Sox beat the Baltimore Orioles on Monday afternoon, Justin Masterson kept himself busy by attending the Boston Celtics 118-115 win over the Chicago Bulls later that night.

Before the game, Masterson delivered an inspirational speech to the Celtics and it’s obvious it worked since they pulled it out on a Ray Allen three pointer with two seconds left in the game.
