Bobby Meacham scored the tie-breaking run on a two-out error by Cleveland first baseman Pat Tabler in the fifth inning and the Yankees beat the Indians, 2-1, in New York last, giving them their best start (11-4) since 1958.
Ron Guidry (3-0) yielded 10 singles and struck out four to move into second place on the Yankees' all-time list with 1,529, three more than Red Ruffing. Whitey Ford is the leader with 1,956 strikeouts.
The Yankees had only four singles off Neal Heaton (0-1) in seven innings and one single off Ernie Camacho in the eighth inning.
Meacham drew a leadoff walk in the fifth and stole second -- despite a pitchout -- one out later. After Willie Randolph (15-game hitting streak) flied out, Don Mattingly's routine grounder got past Tabler.
Earlier, the Yankees placed catcher Butch Wynegar (pulled groin muscle) on the 15-day disabled list retroactive to April 21 and called up catcher Phil Lombardi from Class AAA Columbus.
*Mariners 3, A's 1: Alvin Davis and Ken Phelps hit home runs, the only two hits allowed by Oakland's Jose Rijo in 8 1/3 innings, leading Seattle to the victory in Oakland.
Rijo struck out 14 and came within two of the major-league record for strikeouts in two consecutive games, with a total of 30. Rijo struck out 16 in eight-plus innings on Saturday night when he beat the Mariners in Seattle.
Nolan Ryan, with the 1974 California Angels, and Dwight Gooden of the 1984 New York Mets totaled 32 strikeouts over two games.
Rijo (1-1) and reliever Steve Ontiveros combined on a two-hitter -- Davis' two-run homer in the fourth and Phelps' one-run homer in the ninth.
