The White Sox and Mariners pitched like division leaders, even though Seattle isn't playing like one.
Ray Durham's tiebreaking homer in the eighth off Freddy Garcia sent AL West-leading Seattle to its 12th loss in 14 games, 2-1 against Chicago on Sunday.
Chicago, which leads the AL Central by eight games, held Seattle to four hits for the second time in the three-game series.
Sean Lowe came out of the bullpen for Chicago in place of James Baldwin, whose start was moved back to Tuesday because of a tired arm. Lowe gave up one run, four hits and two walks in five innings.
Manager Jerry Manuel said more starts might be assigned to the right-hander.
"He really pitched well," Manuel said.
"If they want me to start again, fine," Lowe said. "If they want me to go back to the bullpen, I'll do that, too. It doesn't matter to me right now. I just want to win."
Rookie Lorenzo Barcelo (2-1) pitched three perfect innings of relief for the win. Keith Foulke pitched the ninth for his 24th save.
"We held Lorenzo back last night just for today," Manuel said.
Yankees 7, Athletics 5

Angels 10, Indians 9
Tim Salmon hit a tiebreaking homer in the fifth and Anaheim held on to beat Cleveland.
Salmon's 30th homer made Anaheim the first AL team to have four players with at least that many. Salmon also had a two-run double in a five-run sixth.
Chuck Finley (10-10), making his first start in Anaheim as a visiting player, allowed season highs of 11 hits and eight runs in 5 1-3 innings.
