The Atlanta Braves are trying to capitalize on a favorable schedule so they can create some separation in the NL wild-card race.
So far, it's not going according to plan.
Atlanta (76-60), which holds the top wild-card spot, has five series in a row against teams with losing records. However, the Braves have averaged 3.0 runs and are batting .222 in that stretch so far, contributing to a 3-5 record.
They still have three-game series at New York and Milwaukee upcoming, and they've won seven of eight against the Mets and seven straight versus the Brewers.
Until then, Atlanta will try to re-establish its success against the Rockies (56-78) after falling 6-0 Tuesday following a 6-1 victory in the opener of this four-game set a day earlier.
McCann may be back to provide a lift after missing three games following a pain-relieving injection in his sore right shoulder.
The catcher has a .362 career average against Colorado and is batting .405 in his past 11 meetings. McCann, though, was hitting .171 with two RBIs in 22 games before needing the cortisone shot.
Mike Minor (7-10, 4.79) is scheduled to face the Rockies for the first time since getting hit hard at Coors Field on May 5. The left-hander was tagged for career highs of eight runs and 10 hits while walking four in five innings but escaped without a decision in a 13-9 victory.
He's 1-3 with a 3.98 ERA over his last five outings, and is coming off his worst performance of that stretch.
Minor failed to hold a 4-1 lead and gave up four runs in five-plus innings Friday before leaving with the score tied in an 8-5, 10-inning loss to Philadelphia.
"If they give me runs, I need to go out there and shut that inning down," he said.
Carlos Gonzalez will try to solve Minor again after going 3 for 3 with a double and two RBIs on May 5. The left fielder is 10 for 26 in his last six games, collecting a double and a solo homer Tuesday.
The Rockies have a major league-worst 5.18 ERA, but they've compiled a 2.42 ERA while winning six of nine on the road.
Alex White (2-7, 5.58) will try to continue Colorado's road success in his first start against Atlanta. He's 0-1 with a 4.03 ERA in seven starts since being recalled from Triple-A Colorado Springs, with his last victory in the majors coming at home against the Los Angeles Dodgers on June 3.
The right-hander is 1-5 with a 6.61 ERA in 11 road starts, dating to last season.
White struggled again Friday, giving up three runs and four hits with three walks in 3 2-3 innings of a 5-4 loss to San Diego.
"I felt like I took a step in the wrong direction," White said. "I've got to get back on track here. I had good stuff. Command, once again, is just killing me. I got to fix it, and I'm trying to get there."
