Scott Van Slyke has bounced between the Dodgers and the minors five times this season, even smiling whenever manager Don Mattingly approached him with the news that he would be going back down again. Van Slyke had his teammates grinning with a pinch-hit two-run homer in the bottom of the 11th inning that gave the Dodgers a 5-3 win over the Arizona Diamondbacks on Tuesday night.
