Wilin Rosario is scheduled to undergo an MRI on his sore left hand Monday in Phoenix, Arizona.

The Rockies open a three-game series with the Diamondbacks on Monday night, and it sounds like Rosario will sit. "It's been feeling a little weak," he said Sunday. "It's hard to tell (what's going on), because when I was back in Denver I felt it, then (Saturday) night I felt it in another part of my hand."

Wilin Rosario is not in the Rockies' lineup Sunday due to a sore left hand.

"He's OK, but his hand is pretty sore, though," manager Walt Weiss said Sunday. "He felt it on his swing last night. It's a little tender." Weiss added that he doesn't think it's a DL situation for Rosario and they're "looking at him day to day here." Jordan Pacheco is starting in Rosario's place Sunday.

Wilin Rosario hit his first home run of the season Sunday, but the Rockies lost to the Giants.

Rosario hit 21 homers last season and is one of the more powerful catchers in the game, so it's surprising that it took 13 games to hit his first homer of 2014. It was only his third RBI and the 25-year-old is batting just .211, both numbers that should fix themselves quickly. He's not in the lineup for his defense, after all.

Rockies manager Walt Weiss said that Wilin Rosario will get "plenty of work" at first base this spring.

The Rockies want to keep Rosario's bat in the lineup as much as possible, so they'll give him some time at first base this season on days when he needs a break from catching. The 25-year-old has started four games at the position in his career.
