Home run? Double? Who knew? Not Troy Tulowitzki. The Rockies shortstop was running all-out when a fan grabbed his fly ball by the top of the wall in left field. The umpires initially ruled the fan had reached over the wall and awarded Tulowitzki a double. One minute later, they changed their minds. Tulowitzki wound up with a two-run homer in the eighth inning, and the Rockies held on for a 5-4 victory Tuesday night that ended their streak of six consecutive losses to the Cincinnati Reds.
