Josh Naylor delivered a clutch, three-run double in the seventh inning as the Guardians continued their best start in 25 years with a 6-2 win over the Oakland Athletics to complete a three-game sweep. With the Guardians up 3-2, Naylor, who celebrated a two-run homer on Saturday by bashing the top of his helmet with his bat, doubled with the bases loaded. He’s batting .406 with 14 RBIs in nine home games. The surprising Guardians are 16-6 for the first time since opening with that mark in 1999. Will Brennan homered for Cleveland. Brent Rooker homered for the A’s. Ross Stripling lost his fifth straight start with Oakland.
