Orioles (50-72) at Chicago White Sox (62-60)
Led by a Brian Roberts home run binge, the Orioles have now won back-to-back games on their current road trip and could win their first series since the All-Star break with a victory tonight.
Roberts hit his 4th career Grand Slam, leading the O's past Tampa on Thursday. Last night he homered twice as the O's beat Chicago 5-1 in the opener of a three-game series.
Over the last three games, Roberts is 6 for 14 with four homers and 8 RBI. He has hit five homers in the last six games and 14 on the season.
During his current 11-game hitting streak, Roberts is batting .385-5-13. He hit a career-high 18 homers in 2005.
His power surge has helped the O's to just their second two-game win streak of the second-half.
The last time the Orioles won three in a row was when they swept a weekend series at Philadelphia from June 19-21.
Tonight, at 7:05 p.m. in game two of the series in Chicago, David Hernandez (4-5, 4.20) pitches for the O's vs. John Danks (10-8, 3.96).
The O's are 0-9-1 in series since the All-Star break.
With Friday's loss, Chicago lost a game in the standings to the Tigers and now trail Detroit by 3 Â½ games for the AL Central lead. Chicago is 7 Â½ games out in the wild-card race.
The Sox had been a hot-hitting club at home until Jeremy Guthrie slowed them down Friday. Over their last 29 games at home, the Sox are 19-10 and batting .285 as a team and scoring 5.8 runs per game.
The Sox are 2-2 on this homestand and have won eight of their past nine home series.
For Chicago, 15 of 34 games in the second-half have been decided by one run and Chicago is 7-8 in those contests.
