Orioles aim to move closer to Red Sox in AL East

The Baltimore Orioles try to draw even closer to the Boston Red Sox in the American League East on Friday when the division rivals play the second of four games at Camden Yards.

Baltimore moved within 2 1/2 games of the first-place Red Sox on Thursday, as Chris Davis' RBI single in the bottom of the 13th lifted the Orioles to a 5-4 win in the opener.

In his third inning of work, Alex Wilson (1-1) walked Nick Markakis with two outs and Adam Jones singled to right. Davis then followed with a bloop single to left to plate the winning run.

"Long day of travel followed by a long game," Wilson said. "It's just one of those things that seems to be happening a lot this year with everybody."

Davis, who leads the majors with 21 home runs and is second with 56 RBI, ended with two RBI for the Orioles, who have won four of five.

"We had some opportunities, we just didn't cash in," said Jones, whose team left 16 men on base. "But that's why we keep grinding. We never gave up."

Baltimore starter Kevin Gausman allowed two runs on six hits while striking out five over 5 1/3 innings. T.J. McFarland (1-0) tossed a scoreless 13th to pick up the win.

David Ortiz and Mike Carp hit back-to-back homers in the fourth for the Red Sox, who went 1-for-7 with runners in scoring position. Stephen Drew and Jacoby Ellsbury each knocked in a run.

Getting the call for the O's on Friday will be righty Chris Tillman, who is 6-2 with a 3.89 ERA. Tillman won his second straight start and third consecutive decision on Sunday against Tampa Bay, as he allowed three runs (2 earned) and four hits in six innings.

Tillman is 1-1 in six starts versus the Red Sox with a 2.97 ERA.

Boston, meanwhile, will counter with righty Ryan Dempster, who has won his last two starts. Dempster beat the Los Angeles Angels of Anaheim on Sunday, as he limited them to three runs in six innings to improve to 4-6 to go along with a 4.40 ERA.

"When he's able to leverage the ball and throw the ball downhill ... this is what he's capable of doing," Boston manager John Farrell said.

Dempster has faced the Orioles three times and is 1-0 against them with a 1.47 ERA.

Baltimore is 3-1 against the Red Sox this season after taking 13 of the 18 matchups a year ago.
