Slugger Chris Davis, who has been sidelined with a left oblique strain, will be back in action Sunday afternoon when the Orioles wrap up a three-game series with a chance to sweep the Astros at Oriole Park at Camden Yards.
Davis was activated from the disabled list Sunday and will start at first base. Davis is hitting .250 with two homers and 13 RBIs in 22 games this year and played a rehab game at Double-A Bowie on Saturday.
The slugger will be facing a hot pitcher in Astros right-hander Jarred Cosart, who is 0-1 with a 1.83 ERA in his last three starts. Cosart went toe-to-toe with Max Scherzer on Monday in Detroit, giving up one unearned run and four hits in seven innings.
Cosart didn't get the decision in that game despite the strong outing, which has been a common theme among Astros relievers this year. Astros starters have posted a 2.94 ERA in the first six games of their seven-game road trip, but Houston only has one win on the trip so far.
That's because the Astros' bullpen has struggled to hold leads this year, but manager Bo Porter said the starting staff hasn't become discouraged.
"You've just got to come out each and every turn you get the ball and go as long as you can and put the team in position to win the game," he said. "You don't have control what happens after you leave the game."
Right-hander Chris Tillman will start for the Orioles and is facing the Astros for only the second time in his career. He held the Astros to one earned run in seven innings June 4, 2013 in Houston.
Orioles: Wieters placed on DL
Orioles catcher Matt Wieters was placed on the 15-day disabled list on Sunday to make room for Davis' return. Wieters has been limited by a right elbow strain.
He had gone 1-for-13 (.077) in his past three games, all Baltimore victories.
Astros: Lineup remains work in progress for Porter
Porter is still looking for the right lineup combinations, which has been a challenge considering the team's offensive struggles. Porter put Matt Dominguez back in the No. 4 spot in the order Saturday after trying Chris Carter and Jesus Guzman there in recent days.
Dominguez entered Saturday hitting .333 (5-for-15) in his last four games, including a two-run homer Thursday in Detroit. He had a pair of doubles in Friday's series opener.
"I'm just trying to get someone that we can actually put there and leave them there that can drive in some runs with men in scoring position," Porter said. "Dominguez has swung the bat much better now. I'm just trying to find someone to drive in runs."
Porter also dropped Jonathan Villar back to the bottom of the lineup Saturday after he hit second the previous two games. Porter said it had nothing to do with the performance of Villar, who failed to get a key bunt down in the sixth inning Friday, but rather that catcher Jason Castro had returned to the top of the lineup after sitting out two games.
• Orioles outfielder Nick Markakis has a 17-game hitting streak during which he's hitting .357 with eight walks, three doubles, two homers and eight runs scored.
• The Astros lead the Majors with seven steals of third base after Villar and Jose Altuve both swiped third in the third inning Saturday.
• Astros rookie outfielder George Springer, who homered Saturday, is hitting .293 with two homers and six RBIs in the team's last 10 games.
