DENVER -- Rockies shortstop Troy Tulowitzki's opposite-field homer and his RBI double off Astros left-hander Erik Bedard on Wednesday night were reminders of what used to be commonplace.
The strong night against Bedard lifted Tulowitzki's batting average this season against lefties to .269, which is well below some of his high standards. He posted a .333 average against southpaws in 2007, .330 in '08, .342 in '10 and .349 in '11.
It's not as if Tulo's struggles against lefties are ruining his year. He went into Thursday leading the National League in slugging percentage, at .633, and OPS, at 1.037, and was tied with the Reds' Brandon Phillips for the RBI lead at 43.
"I remember looking, and I led the league one year against lefties, so I think it's one of those things where I've hit into hard outs and haven't faced them on a normal basis," Tulowitzki said. "Another thing is some of the lefties in our division are tough matchups against me, so that's brought my average down."
