DENVER -- To better mimic the club's four-man rotation, the Rockies are considering moving Jhoulys Chacin's simulated game up to Saturday. It was previously scheduled for Sunday.
"The thought process behind this is that we're trying to get him [pitching on shorter rest] on somewhat of a regular basis," manager Jim Tracy said.
Chacin (right shoulder inflammation) has been on the disabled list since May 2 after beginning the season 0-3 with a 7.30 ERA. He used his full complement of pitches on Tuesday, throwing 30 during a simulated game -- 15 per inning. The Rockies expect Chacin to add an extra inning -- 15 pitches -- while sticking mostly to his hard stuff as he focuses on command of his fastball, which plagued him in five starts this year.
Tracy expects Chacin, whenever he returns, to rejoin the starting rotation.
"We'll have to wait and see how he does, how much volume he can take on, especially early on," Tracy said, noting Chacin will have to improve his recovery ability. "We'll see how he bounces back from each [simulated game]. His arm strength seems to be in the direction you'd want to see it moving in, so it's safe to say he passed that test.
"If he has a setback, we'll reel him back in. but right now, we're trying to move him forward."
Nelson released from hospital
DENVER -- Chris Nelson was released from Sky Ridge Hospital Tuesday night and is resting comfortably at home.
Nelson, hospitalized Monday with an irregular heartbeat, underwent a successful shock treatment Tuesday to help his heart return to a regular rhythm. Manager Jim Tracy said Nelson was in the clubhouse during Tuesday's game against the Pirates, though he did not get a chance to speak to him.
"My understanding is he'll stay at home for a couple of days," Tracy said.
Nelson, 26, was put on the 15-day disabled list on Monday.
Rosario not thinking about Rookie of the Year honors
DENVER -- Likening himself to a kid at Christmas, Wilin Rosario is trying not to get his hopes up about his Rookie of the Year chances.
"I think if I got it, I'd be happy," Rosario said. "But I don't want to start thinking about it, because there are a lot of good rookies out there. When you're expecting a happy Christmas and you don't get the gift you wanted, it's a disappointment. I don't want to build it up for myself."
Rosario, who was not in the Rockies' lineup Wednesday, leads National League rookies in homers (15) and RBIs (39). Rosario's 15 homers are also the most among NL catchers, with his .535 slugging percentage second.
Rosario also knows he'll need all the help he can get, as voters might penalize him for the Rockies' poor record (35-55) and his defense, which is a work in progress. And then there's the chore of beating out popular Nationals outfielder Bryce Harper.
"I want to say thank you to [the media], because you give good support and say nice things about me," Rosario said. "We'll see if the award gives me something to be happy about at the end of the year."
Fowler back in leadoff spot, CarGo third
DENVER -- The Rockies got two hits apiece from their third and fourth hitters -- Dexter Fowler and Carlos Gonzalez -- in Tuesday's 6-2 loss to the Pirates.
But for the first time since July 4, their leadoff hitter did not get on base. Eric Young Jr. went 0-for-5 Tuesday with a strikeout.
Fowler leads the National League in batting average from the leadoff spot (.353) and he was back in his familiar spot Wednesday. Gonzalez hit third after two games in the No. 4 hole.
"Because of the way we're structured today, you don't want the game to end with CarGo standing on the on-deck circle," manager Jim Tracy said. "If the game is hanging in the balance and there's one more at-bat to be taken, you'd feel a lot better that it's [Gonzalez] in that situation."
Andrew Brown, called up Tuesday to replace Jonathan Herrera (15-day disabled list, left wrist infection) hit fourth.
Brown went 0-for-1 with a flyout to right Tuesday night as a pinch-hitter. In 86 games with Triple-A Colorado Springs, Brown hit .317 with 20 homers and 84 RBIs.
"Wherever I can get plugged in, I'll do my job best as I can, try to hit the ball as hard as I can," said Brown, who was claimed off waivers from St. Louis last October.
