Cody Poteet allowed one run in six innings of his first major-league appearance in nearly two years, and Juan Soto broke things open with a three-run homer, as the visiting New York Yankees completed their doubleheader sweep of the Cleveland Guardians with an 8-2 victory Saturday night.The right-hander Poteet (1-0) did not pitch in the majors last season while recovering from Tommy John surgery, and made his last big-league appearance in July 2022 for the Miami Marlins.However, in his first major-league start since May 25, 2022, Poteet contained the Guardians, despite allowing six hits, and gave up his only run on a fifth-inning homer to ex-Yankee Estevan Florial. He didn’t issue a walk and struck out four.Meanwhile, Soto’s third homer of the season highlighted a four-run fourth for New York, which won 3-2 earlier in the day and is an MLB-best 12-3 — and 8-1 on the road. Anthony Rizzo had two hits and an RBI in the nightcap.The Yankees roughed up Cleveland’s Triston McKenzie (1-2), who allowed six runs — five earned — and walked six in four innings. Josh Naylor added a ninth-inning homer for the Guardians, who have dropped three of four after winning five straight.
