Dexter Fowler is chock-full of cool. He walks in with Jordans on his feet, and a smile smuggled from a toothpaste commercial.

But mention last season, and he simmers.

"I just really want to win. I got (upset) with myself last year, and (upset) with the (guys)," Fowler said Thursday before participating in a voluntary workout. "We all could have done a lot better. We know that."

Poor pitching has become such a part of the Rockies that it dominates the narrative. Colorado will remain bugs on the windshield in the National League West without more consistency from its rotation. But, as Fowler sees it, the road back from an awful finish starts at the top.

Even after a breakthrough season during which he set career highs in hits, home runs and on-base percentage, Fowler, 26, said he believes he and the offense can be more explosive.

"We need to put pressure on everybody everywhere. On the road, let's put the pressure on them early. From the first pitch of the game, let's go. No waiting and taking pitches. Let's go. Then, it's 1-0 already. I think that will help our pitchers out," Fowler said. "I take responsibility. It starts with me."
