When Andrew Benintendi batted in the seventh inning on Wednesday, NESN's Dave O'Brien said that Benintendi's game-winning hit from the previous night was actually a single and not a double. (The live play-by-play at ESPN.com referred to it as a double, but I don't know when the change was made.)
Both O'Brien and Jerry Remy displayed an ignorance of the rule book when they discussed the play.
Dave O'Brien: It's an interesting debate what happened last night to end the ball game, in 12 innings when Benintendi hit that searing line drive to right. It was a game-winning single, officially.
