Red-hot Rockies roll to top spot

Pop, it seems, restored the pop.

After Rockies shortstop Troy Tulowitzki began the season 0-for-8 in his first two games, he swapped out one pop song (Katy Perry's "Firework") for another (Justin Bieber's "Baby") -- and in his second at bat of game No. 3, he homered. In fact, since making the change in music, Tulowitzki has hit .393 with three doubles and five home runs.

This hot streak doesn't quite compare with the 14-home-runs-in-15-games barrage he went on last September, but it has coincided with another Rockies hot streak. Colorado went 13-2 in that stretch of September, and it is now 8-1 in its last nine games. Even without ace Ubaldo Jimenez, the rotation hasn't lost a start -- the club's one loss in that stretch was a 14-inning affair with the Pirates -- and has compiled a 3.04 ERA in 53 1/3 innings.

Paced by their shortstop, the Rockies are on a roll -- one that has shot them up the charts to the top of this week's Power Rankings.
