DENVER -- Center fielder Dexter Fowler was not in the starting lineup on Sunday. He was hit with a pitch on the right hand on Saturday and fouled a ball off his left foot last week.
"Dexter's been getting dinged up over the last week or so," manager Walt Weiss said. "Then on top of that, day game after a night game, I just felt like it was the right time to give Dexter a day [off]."
Fowler pinch-hit in the ninth inning of Sunday's 5-4 loss to the D-backs, drawing a one-out walk before being stranded at third base with two outs representing the tying run.
After Fowler was hit with a Trevor Cahill pitch in the third inning Saturday night, trainer Keith Dugger brought Fowler into his office and said he took seven images of Fowler's hand and wrist with a fluoroscope that Dugger had just received Saturday.
"It's on trial right now, but it was perfect," Dugger said of the device.
Fowler stayed in the game and finished 0-for-3. He has one hit in his past 15 at-bats, but Weiss said what Fowler has done lately at the plate was not the reason he wasn't in the lineup.
"He's had some quick at-bats, and they're mounting up a little bit," Weiss said. "But I'm not too concerned about that. Dexter's been swinging the bat really well. I'm more concerned about the physical thing."
Chacin placed on DL with back strain
DENVER -- Manager Walt Weiss said the Rockies have not decided who will start Wednesday in place of Jhoulys Chacin, who was placed on the 15-day disabled list with a back strain and is scheduled to undergo an MRI on Monday.
Right-handed reliever Rob Scahill, 26, was recalled Sunday from Triple-A Colorado Springs, where in five games, he was 2-0 with a 4.26 ERA. He was in uniform Sunday for the Rockies. Scahill pitched in six September games for the Rox last year with no record and a 1.04 ERA.
Chacin is eligible to come off the disabled list on May 5, meaning he will miss at least two starts. After that, barring any postponements, his next turn would come up May 5 against the Rays at Coors Field. Chacin said he felt better Sunday than he did a day earlier.
The possibility of bad weather and a postponement could allow the Rockies to push their starters back a day and avoid the need of replacing Chacin on Wednesday against the Braves. Otherwise, the Rockies will have to bring a pitcher up from Colorado Springs to start.
"There's a few options down there that we could go to," Weiss said. "We're not sure who we're going to use in that spot yet. I imagine we'll have a pretty good idea in the next 24 hours or so."
Left-hander Drew Pomeranz pitched on Thursday and Tyler Chatwood started on Wednesday. Pomeranz worked 5 2/3 scoreless innings with one walk and nine strikeouts in his last game at Reno. In three starts, he's 2-0 with a 3.31 ERA and five walks and 21 strikeouts in 16 1/3 innings.
Chatwood, who has been the most consistent Colorado Springs starter, is 1-0 with a 1.84 ERA in three starts with four walks and 17 strikeouts in 14 2/3 innings. He worked four scoreless innings with two walks and six strikeouts in his last start at Reno.
Helton to miss third game, DL stint possible
DENVER -- First baseman Todd Helton, who has a left forearm strain, did not play for the second straight game on Sunday. Helton suffered the injury when his hand came off the bat on a swing in the first game of a doubleheader Tuesday against the Mets. The Mets and Rockies were snowed out Wednesday, but Helton played Thursday against the Mets and Friday against the D-backs before resting Saturday.
Helton said he received an anti-inflamatory injection Sunday and will not play on Monday against the Braves. Helton said if his forearm is still store Tuesday, a trip to the disabled list could be considered.
After going 2-for-21 to open the season, Helton is hitting .268 (11-for-41) with three doubles, one homer and 10 RBIs. At 39, Helton is in the final year of his contract and possibly playing his final season in a career spent entirely with the Rockies. For them to get off to such a torrid start has been particularly satisfying and enjoyable for Helton.
"The [wins] are just a product of everything else we do right," Helton said. "You're going to go through bad stretches, we know that. But it's OK. The way we play the game right now, our energy, our competitiveness -- it's just fun to show up at the ballpark every day. I'm having the time of my life. I really am."
Torrealba-De La Rosa pairing a rousing success
DENVER -- When Rockies manager Walt Weiss played for the Braves, teammate Greg Maddux pitched regularly with backup catcher Eddie Perez behind the plate rather than Javy Lopez, who was the Braves' starting catcher. As a manager, Weiss is pairing backup catcher Yorvit Torrealba with southpaw Jorge De La Rosa, who has a string of 17 consecutive scoreless innings and is 2-1 with a 2.82 ERA in four starts, all with Torrealba catching.
"It is evolving," Weiss said of the Torrealba-De La Rosa pairing. "I think Jorge's real comfortable with him. I think Torrey brings out the best in De La, so right now it's a real good fit. And at the same time, it's keeping Torrey involved."
De La Rosa is the first Rockies pitcher to make consecutive scoreless starts of at least six innings since Jason Hammel made three straight scoreless starts from June 7-18, 2010, all at Coors Field. Hammel's three outings, all of which he won, totaled 22 2/3 scoreless outings -- 7 1/3 innings against the Astros, eight against the Blue Jays and 7 1/3 against the Brewers.
• Don Baylor's father, George, died Friday night in Austin, Texas. Baylor is the D-backs' hitting coach and was the Rockies' first manager, guiding the team from 1993-98.
• Jonathan Herrera started at second base on Sunday. It was his third start of the season and his first since the first game of Tuesday's doubleheader with the Mets.
"Keeping guys involved is just as important as giving guys a day [off] here and there," manager Walt Weiss said.
• While winning the first two games of this series, 3-1 and 4-3, the Rockies totaled nine hits, but seven of them went for extra bases.
