(SportsNetwork.com) - Chris Tillman eyes his first win in more than a month on Tuesday when the Baltimore Orioles continue their three-game series with the Houston Astros at Camden Yards.

Tillman opened the year by winning two of his first three starts, but has lost his last four decisions and has seen his ERA swell to 6.10. Tillman may have been on his way to his first win since April 18 on Thursday against Seattle, but a rain delay cut his outing short after just three innings. He had given up a run and one hit, but walked three batters before the rain came.

Tillman is 2-1 in three starts versus the Astros with a 2.41 ERA.

Houston, meanwhile, turns to righty Scott Feldman, who is 3-4 with a 5.17 ERA. Feldman did not get a decision on Thursday in Detroit, but did not pitch well, as he surrendered five runs (4 earned) and 10 hits in six innings of his team's 6-5 loss.

"Really had to rely on one speed all day, didn't have anything to get them of my fastball," Feldman said. "Pretty impressive job by the guys fighting back, making it a game after I'd got us in that hole early."

Feldman has faced the Orioles 14 times (8 starts) and is 4-2 with a 4.85 ERA.

Baltimore drew first blood in this series on Monday, as Steve Pearce's two-run homer in the seventh inning lifted the Orioles to a 4-3 win over Dallas Keuchel and the Astros.

Keuchel (6-1) seemed to be on his way to another win as the Astros entered the bottom of the seventh with a 3-2 lead. The left-hander had retired 11 straight batters before giving up a one-out single to Delmon Young. Pearce followed with a blast to right-center field to put the Orioles ahead for good.

"Pearce's first-pitch home run, that was impressive, just because nobody really puts a swing on that pitch," said Keuchel. "I've never seen one this season like that. But you got to give credit to their guys and I just got to do a better job."

Keuchel gave up all four runs on six hits with three strikeouts and one walk over eight innings. The 27-year-old saw his career-long winning streak of eight games come to an end, losing for the first time since Aug. 21, 2014.

Baltimore starter Wei-Yin Chen allowed three runs on 11 hits while striking out six over five innings. Brad Brach (2-0) tossed two perfect innings to pick up the win.

Oliver Drake tossed a scoreless eighth for Baltimore and Zach Britton pitched a perfect ninth for his 11th save of the season.

"They had their pops at Wei-Yin, but he held them when he had to," said Orioles manager Buck Showalter. "It's not easy. Pitching is hard, especially against that team. They have a lot of ways to beat you."

Baltimore took four of seven from the Astros last season.
