I agree, it is the smart thing to do. With the winning run at third, less than two outs, almost any ball hit to the outfield likely ends the game. In this case it backfired, because two outfielders is usually one in left-center and one in right-center. But the ball was hit to center, so if there had been three outfielders there would have been a centerfielder, and the ball was hit low enough that a centerfielder might have been able to hold the runner at third. Doesn't mean it was the wrong call though.
