Although Jhoulys Chacin escaped a serious oblique injury, he couldn’t escape the 15-day disabled list.

The Rockies placed the right-hander on the DL on Sunday afternoon with a left lower back strain. Chacin suffered the injury in the seventh inning Friday night. His stint on the DL is retroactive to Saturday, so he’s eligible to come off the disabled list May 5. That means he’ll miss at least two scheduled starts.

To replace Chacin on the roster, the Rockies recalled right-handed reliever Rob Scahill from Triple-A Colorado Springs.

Manager Walt Weiss said the Rockies have not decided who will start Wednesday’s game against the Braves in place of Chacin, who is scheduled to undergo a precautionary MRI on Monday.

A pending snowstorm could allow the Rockies to push back their starters a day, giving them a break for Wednesday’s game, but they are still likely to call up a reliever from Triple-A in the next two weeks.

Left-hander Drew Pomeranz pitched Thursday and Tyler Chatwood started Wednesday. Chatwood has been the most consistent Sky Sox starter, going 1-0 with a 1.84 ERA in three starts.

Helton update. Veteran first baseman Todd Helton was not in the Rockies’ lineup Sunday and he doubts he’ll play Monday, either. A strained left forearm is keeping him on the bench, and there’s a chance he could join Chacin on the DL.

“It’s pretty sore right now, but I think it’s going to be all right,” Helton said.

Helton said he thinks he suffered the injury on a swing Tuesday against the Mets in the first game of a doubleheader.

“I’ve never pulled a muscle there before,” Helton said, then joked, “I guess I’ll have to summon my superpowers to heal it up.”

Footnotes. After Dexter Fowler was hit by a Trevor Cahill pitch in the third inning Saturday night, trainer Keith Dugger rushed Fowler into his office and took seven images of Fowler’s hand and wrist with a fluoroscope that Dugger had just received that day. “It’s on trial right now, but it worked perfect. Dexter was like, ‘Wow, I’m good to go,’ ” Dugger said. … Jordan Pacheco, who started for Helton at first base Sunday, went 2-for-4 with an RBI and a run scored. He’s hitting .438 at Coors Field this season, but just .154 on the road.

ATLANTA AT COLORADO

Braves’ Mike Minor (2-1, 0.95 ERA) vs. Rockies’ Jeff Francis (1-1, 8.25), 6:40 p.m. Monday, ROOT; 850 AM

The Rockies face a big test with left-hander Mike Minor on the mound for the Braves. He has a 2.00 ERA over his past 18 starts and has a 0.95 ERA in three starts this season. Though he had a strong performance against the Royals in his last outing (one run and five hits allowed in six innings), Minor suffered his first loss since Aug. 25, a span of 10 starts. He has a very effective curveball. According to ESPN Stats and Information, hitters have chased 49 percent of Minor’s breaking balls out of the strike zone, best in the National League among starting pitchers with at least three starts. The Rockies have chased 32.3 percent of breaking balls, the eighth-highest rate in the league.
