The Orioles enter Saturday 9 1/2 games behind the American League East-leading Red Sox but in the thick of the AL Wild Card race, and after taking the first two games of a four-game series against the White Sox, they will lean on the struggling Wei-Yin Chen to secure a series win.
Chen, who has one win and four losses in his last six starts, is coming off a second consecutive short outing. After lasting just 3 2/3 innings and allowing eight earned runs to the Red Sox on Aug. 27, Chen threw four innings and gave up three earned runs against the Yankees on Sunday.
The 28-year-old left-hander was still confident after his most recent rough start.
"Even though I've had the two bad starts, I still have the confidence in me," said Chen, who walked eight batters the past two games. "I gave out a lot of free passes today. The last time, I gave out free passes, too. This is the thing I need to work on. Next time, I believe I will bounce back, and we'll see."
Another lefty will take the mound for the White Sox, 25-year-old Hector Santiago. Santiago (4-8) also struggled his last time out, allowing four earned runs on five hits, walking five in 3 2/3 innings against the Red Sox.
The 4-3 loss was the first of eight straight for the White Sox, the last two coming at Camden Yards.
Santiago was well aware he did not have his best stuff against Boston.
"I felt fine. It was just one of those days where you go out there and stink," Santiago said. "You can't put anything else on it. I just have to go after it and throw strikes. If you can't throw strikes, you are not going to succeed, that's for sure. It was a tough night."
White Sox: Ventura says Garcia will see extended playing time
White Sox manager Robin Ventura said Leury Garcia, who went 0-for-3 in his Friday start at shortstop, will see significant playing time in the final three weeks of the season.
Garcia, acquired as the player to be named in the trade that sent Alex Rios to the Rangers on Aug. 11, hit .265 with four triples, four home runs, 20 RBIs, 15 stolen bases and 34 runs scored in 55 games between Triple-A Charlotte and Texas' Triple-A affiliate before getting called up by the White Sox.
In eight games with the White Sox, the 22-year-old shortstop is hitting .133 with an RBI and two stolen bases. Ventura said he plans to start Garcia at second base Saturday.
"Just want to give him enough opportunity and let him move around," Ventura said.
• Right-handed reliever Ramon Troncoso, who was on the disabled list since Aug. 17 with pericarditis, was reinstated from the 15-day disabled list prior to Friday's 4-0 loss to the Orioles.
Orioles: Dickerson latest of September callups
The Orioles called up Chris Dickerson from Triple-A Norfolk on Friday and designated infielder Alex Liddi for assignment, making room for Dickerson on the 40-man roster.
Dickerson was with the Orioles from mid-April until the end of July, hitting .245 with four home runs and 13 RBIs in 46 games. He went 0-for-1 in his return.
Liddi hit .222 in 49 games with Norfolk since the Orioles acquired him from Seattle about two months ago.
• Manager Buck Showalter said he had lunch with pitching coach Rick Adair on Friday, but he did not want to speculate on whether Adair would return to the team this season.
Adair took a personal leave of absence on Aug. 16 to see his ill father in Birmingham, Ala., and Bill Castro stepped into his position.
• In two career starts, Chen is 1-0 with a 2.38 ERA against the White Sox. Santiago has a 4.00 ERA in a start and two relief appearances against the Orioles.
