Wilin Rosario walked through the Rockies' clubhouse Wednesday with ice packs on his thighs. All he needed was a tear-away jersey and he would have been a dead ringer for former Houston Oilers running back Earl Campbell.

"Who?" Rosario said looking puzzled.

Campbell was a bulldozer. Rosario is simply a bull. His work as a designated hitter Friday night at Camden Yards — a double and crucial home run — provided yet another reason to wonder if he'd be better off at a position besides catcher. The Rockies won 6-3 over the Orioles bashing and belting their way to the sixth win in their past seven games.

This was unexpected on multiple levels though not by Rockies manager Walt Weiss. "This trip will be different if our offensive carries over" Weiss said. "That's the key."

The Rockies are the one team in major-league history that can dominate a homestand and head out on the road with absolutely no momentum. Colorado had lost 22 of its past 29 road games. But Weiss if not multiple players insisted Friday was going to be a fresh start.

Words weren't necessary to explain why. The soundtrack sufficed. The Rockies belted four home runs all carrying varying degrees of significance and volume. Rookie left fielder Charlie Culberson hit his first homer a laser to left field (the fan who caught it threw it back so he retrieved the souvenir). Charlie Blackmon hit only the 73rd ball onto Eutaw Street beyond right field and just the 44th by an opponent.

Eutaw features metal discs documenting the longest shots. Blackmon will get honored for his blast. "Heck yeah I am pumped about it" Blackmon said of getting a plaque in honor of his home run. "It's not like I have a lot of plaques with my name on it."

Todd Helton hit the 362nd of his career one more than Joe DiMaggio.

But when it comes to raw power nobody on the Rockies eclipses Rosario. Carlos Gonzalez's swings translate more consistently in games. Rosario however has the most voltage in his swing according to hitting instructor Dante Bichette.

It raises the question: How many homers could the kid hit if he didn't have to deal with the physical and mental grind of catching? He's improved behind the plate but the idea of having him appear in 150 games can't be dismissed out of hand.

Rosario hit his 17th home run of the season continuing a surge that has renewed talk about his scary offensive potential. He has 11 hits in his past 27 at-bats including a pair of homers and two doubles. He has driven in 11 runs during this stretch.
