After Roberts led off the fifth with a homer to make it 2-2, the Orioles placed runners at the corners with no outs but couldn’t score when the next three batters failed to get the ball out of the infield.

The Orioles took a 1-0 lead four batters into the bottom of the first on Chris Davis’ two-out double to score Manny Machado, who singled earlier in the inning. Davis’ double was his majors-leading 87th extra-base hit of the season.

Davis’ RBI was his 124th of the season, tying him with Eddie Murray (1985) for fourth on the Orioles’ single-season list.

Orioles starter Wei-Yin Chen retired 10 of the first 11 batters he faced before back-to-back hits in the fourth — a one-out double by Alexei Ramirez and Paul Konerko's RBI single — tied the game at 1.

Dayan Viciedo put the White Sox (56-85) up 2-1 in the top of the fifth inning, belting a solo homer to center field on a 2-2 pitch from Chen.

Chen allowed two runs on five hits, removed after six innings and 99 pitches. For most of the afternoon, Chen kept the White Sox off balance, striking out seven and walking none. Chen owns a 2.63 ERA in three career starts against Chicago.

“I didn’t really worry about my velocity, I just worried about my location,” Chen said through interpreter Tim Lin. “And pretty much my location was really good today.”

Right-hander Darren O’Day tossed two scoreless innings in relief of Chen. He overcame a leadoff single in the eighth by pinch hitter Jordan Danks when catcher Chris Snyder threw out Danks attempting to steal second. Snyder’s throw skipped in front of Roberts, but the second baseman corralled it and applied a sweep tag in time. Jim Johnson needed just eight pitches to retire the White Sox in order in the ninth for his sixth straight scoreless outing.

With one out in the 10th, Hunter left a 3-2 curveball up and Gillaspie took it over the scoreboard in right. Hunter has allowed homers in two of his past three outings after not allowing a home run in his previous 22 appearances.

“Tommy just left a breaking ball out over the plate,” Showalter said. “But Matty had a big hit for us. … I thought we deserved it. It was frustrating, but we finally break through there at the end.”
