They might need another scoring surge with the way Scott Feldman has pitched at his new home.The Orioles will try to stay hot offensively and win their fourth in five games Saturday night when Feldman faces Kendrys Morales and the visiting Seattle Mariners.After totaling 19 runs and batting .213 while losing six of eight, Baltimore (61-49) has piled up 17 runs and 22 hits in its last two following an 11-8 victory in Friday's series opener.Davis hit his major league-leading 40th home run and Nate McLouth broke open a close game with a sixth-inning grand slam. With his third homer in four games, Davis became the fifth Oriole to hit 40 homers in a season, joining Brady Anderson (50), Frank Robinson (49), Jim Gentile (46) and Rafael Palmeiro (43)."It's pretty good company to be in," Davis said. "I'm proud of the way things are going this year. Still got a lot more work to do, but it's nice to be a big part of a winning team."Morales is 13 for 17 over his last four games following consecutive four-hit performances. He's the first Seattle player to record back-to-back four-hit games since Ichiro Suzuki on June 6-7, 2006.Morales will attempt to continue his tear against Feldman (2-2, 5.12 ERA), but he's 2 for 13 lifetime in this matchup.Feldman has allowed two runs over 14 innings in two road starts -- both Baltimore victories -- but he's 1-2 with a 7.13 ERA in three outings at home since being acquired from the Chicago Cubs on July 2. He gave up four runs and six hits over five innings there in Saturday's 7-3 loss to Boston.The right-hander may have a difficult time settling in versus the Mariners (50-59). He's 0-4 with a 7.89 ERA while allowing five home runs and 14 walks in 21 2/3 innings in his last five starts against them. He was tagged for six runs and seven hits over 2 2/3 innings before leaving without a decision in an 8-6 loss on Sept. 15 while with Texas.Kyle Seager has gone 4 for 8 lifetime against Feldman and looks to improve his major league-best .398 batting average since July 1.Nick Franklin, however, went 0 for 5 Friday and is hitless in 17 at-bats.The Mariners hope to avoid their eighth loss in 10 games as they give the ball to Erasmo Ramirez (2-0, 7.71), who seeks his third straight win.Although the right-hander has allowed eight walks and 21 hits -- including a home run in each of his three starts -- the Mariners have aided him with 16 runs of support.Ramirez, who has missed most of the season with right triceps tendinitis, yielded four runs and seven hits over six innings in a 6-4 win over Minnesota on Sunday.He pitched well in his only start against the Orioles, allowing two runs and four hits over eight-plus innings in a 4-2, 18-inning loss at Safeco Field on Sept. 18.Baltimore's Matt Wieters went 0 for 7 in that contest and hopes to end a career-worst 0-for-25 drought in this meeting.The Orioles will be without second baseman Brian Roberts, who was put on the paternity leave list Friday awaiting the birth of his family's first son.
