Following an 11-7 start, the Orioles are just 5-13, but opened their three-game series with a 6-5 win Friday to improve to 2-1 on their rain-shortened eight-game homestand.
The Orioles last won back-to-back games on April 27-28.
Baltimore (16-20) hopes Kris Benson (4-3, 4.89 ERA) will stop a slump among its starting rotation that is 0-5 with a 9.23 ERA in the last eight games.
Benson contributed to the slump in his previous outing, allowing a season-high nine runs and four walks in 4 1-3 innings of a 10-3 loss Sunday to Boston.
It was the worst start of the season for the right-hander, acquired from the New York Mets in January for pitchers Jorge Julio and John Maine. Benson had given up four runs or less in his previous six starts.
Benson is 0-1 with a 5.03 ERA in three lifetime starts against the Royals, but hasn’t faced Kansas City since June 10, 2000, when he allowed one run in eight innings of a 2-1, 12-inning loss while with Pittsburgh.
Corey Patterson was the offensive star Friday for the Orioles, going 2-for-3 with four RBIs, including a three-run homer in the second. Leadoff man Brandon Fahey, filling in for the injured Brian Roberts at second base, broke a 5-5 tie in the eighth with a game-winning RBI single to score Patterson.
“I felt like his chance would come,” manager Sam Perlozzo said of Patterson, who spent parts of six tumultuous years with the Chicago Cubs before being acquired by the Orioles in the offseason. “Give credit to the kid. His mental attitude was never down.”
According to Perlozzo, catcher Javy Lopez is expected to return Saturday. Lopez has been on the 15-day disabled list with a strained back and has not played on April 27.
The Royals (10-23) lost for just the third time in their last eight games and have totaled 40 hits in their last three games, raising their team batting average to .252.
Mark Redman will start Saturday as he tries to regain the form that led to a career-high 14 wins with Florida in 2004. The left-hander, who is playing for his sixth team in eight years, was traded to the Royals in December after going just 5-15 with a 4.90 ERA with the Pittsburgh Pirates in 2005.
Redman (0-2, 5.76) has yet to win in five starts after starting the season on the DL, but is coming off his best outing Sunday, when he allowed two runs in seven innings of a 3-2 loss to the Chicago White Sox. The southpaw struck out a season-high six and did not receive a decision.
Redman is 2-4 with a 4.35 ERA in eight games—six starts—lifetime versus the Orioles, who he has not faced since defeating them Aug. 16, 2004, while playing for the Oakland A’s.
The Orioles are 26-11 against the Royals since the start of 2001.
