Rosario returns after bout with dehydration

DENVER -- Rockies catcher Wilin Rosario spent part of Saturday at a local hospital having tests and receiving IV treatments. But, replete with orders to take in more fluids, Rosario was back in the lineup for Sunday afternoon's finale of a three-game set with the Dodgers.

Rosario was scratched from the lineup in Saturday's 5-4, 10-inning victory about an hour before the game because of dizziness brought on by dehydration.

"I was a little bit dizzy and my eyes were dark," Rosario said. "It was the first time that's happened. It wasn't really scary. We're athletic, and there are times when we lose a little hydration. It could be because you don't sleep well or rest, but it's nothing bad. I'm good.

"Nothing serious, but they tell me to drink more water."

Manager Walt Weiss called the issue "a little scary. He was lightheaded and had to go through some tests."

Rosario said Saturday's condition was not related to the flu that cost him 13 days in May. Interestingly, however, he is playing at a weight lower than when he came back from the flu.

When he was sick, Rosario dropped from 228 pounds to 218, and by the time he returned he was 219. Rosario said he wanted to see how well he played at a lighter weight.

On Sunday, he said he was 217 and he wants to stay in that area. He has a .234 batting average for the season, but has hit .269 with a home run and three doubles in his last seven games.

"I've been working hard in the cage," Rosario said. "My swing is pretty good. My power is so-so, but it's getting there. If I keep my swing and swing at the right pitch, the ball is going to go."

Rosario returned to Coors Field before Saturday's game was over and might have been available if the game had extended.

Cuddyer nears return from injured left shoulder

DENVER -- Rockies veteran Michael Cuddyer said his sore left shoulder had made "progress" after two days off, and manager Walt Weiss said it was possible he would be available for Sunday's series finale against the Dodgers at Coors Field.

Cuddyer, the regular right fielder who also plays first and third base, suffered the injury diving for a ball while playing third in the ninth inning of Thursday night's 12-7 loss to the D-backs.

Weiss said Cuddyer wasn't available Saturday, even if the game had extended beyond the 10th inning -- when the Rockies' Brandon Barnes delivered the game-winning RBI triple. 

Weiss gave first baseman Justin Morneau a planned day off from the starting lineup on Sunday. Ideally, the right-handed-hitting Cuddyer would have played first, with Dodgers lefty ace Clayton Kershaw pitching. But in his absence, Weiss started left-handed-hitting Ryan Wheeler at first base.

Barnes started in center field and hit second, behind Charlie Blackmon, who led off. Blackmon, Wheeler and starting pitcher Jorge De La Rosa were the only left-handed hitters in the lineup.

Additionally, Weiss moved DJ LeMahieu to third base and started Josh Rutledge at second. Rutledge was the starter at second last year before LeMahieu won the job and earned the Rockies' Defensive Player of the Year Award.

LeMahieu, however, is capable of playing shortstop and third base, so his ability to move came into play when Nolan Arenado suffered a broken left middle finger on May 23.

"He's been over at third in some double-switches and that type of things and he's played a lot of third in the past," Weiss said. "I wanted to get Rutledge involved and keep him involved. 'Rut' swung the bat well [Saturday, 2-for-4]."

Focused Bergman earns long-awaited callup

DENVER -- The Rockies didn't give right-handed pitcher Christian Bergman the carrot or the stick as he progressed through the Minor League system.

Being a 24th-round pick in the 2010 Draft, Bergman didn't receive the prospect love from outside the organization, or the pressure from inside it. He just pitched and steadily moved ahead when the time came.

"It was hard from the very beginning," Bergman said. "Sometimes felt like I didn't quite get the attention that maybe I thought I should. But a lot of people drafted before me might think the same thing. I tried to just put that out of my mind and focus on the job at hand. I set a goal for each season and try to attain that goal, keep improving year after year.

"I wouldn't say there was definitely a point where they said I'm on the right track, which might've helped in a way, because that bit of uncertainty probably made me a little more driven."

Now Bergman, 26, who pitched four seasons at Cal-Irvine, is every bit as important as Eddie Butler, the 2012 supplemental first-round pick who made his debut on Friday. Bergman, who has been summoned from Triple-A Colorado Springs and will be added to the Rockies' roster to start Monday night against the Braves at Coors field, had the same introductory news conference on Sunday that Butler did before his first start.

The difference was when Bergman met reporters in the clubhouse, he politely said, "Pleased to meet you." Butler, with plenty of prospect hype, already knew everyone. But there's a good reason people now want to know Bergman.

At Colorado Springs, Bergman was 4-4 with a 3.84 ERA. More impressive was his performance at Security Service Field -- 6,531 feet, or more than 1,000 feet higher than Coors Field -- he went 1-0 with a 2.04 ERA in four starts. Bergman doesn't have top-shelf velocity, but he relies on location and know-how.

"Part of it is knowing who I am as a pitcher and going with my strengths," Bergman said. "Part of it is not being intimidated by the fact that it's 6,000 feet or whatever it is. There are some things that are different about it, but for me it's about making adjustments and turning things that are a little different into strengths for me.

CarGo throws, but return from DL still unknown

DENVER -- Rockies left fielder Carlos Gonzalez did some throwing Saturday, but there has been no dramatic change in the condition of his left index finger. Chronic swelling in the finger led the Rockies to place him on the 15-day disabled list Wednesday.

Gonzalez has not been cleared to swing the bat, and the throwing was more to keep his arm in condition, although the swelling affects his ability to grip the baseball.

Asked if he thought Gonzalez would be ready when eligible to return from the DL on June 19, Weiss said, "That's the best-case scenario, but it's hard to tell right now."
