Brent Rooker ended Clarke Schmidt’s scoreless streak at 28 1/3 innings with a solo homer in the fourth inning, Nick Kurtz added a three-run drive in the sixth and the Athletics beat the New York Yankees 7-0 Saturday. Former Yankee JP Sears (6-7) allowed two hits over 5 2/3 innings for the A’s, who had lost five of six and entered a major league-worst 11-31 since May 13. Jack Perkins, a 25-year-old right-hander who debuted last weekend, finished the three-hitter for his first big save and extended his scoreless streak to 6 1/3 innings.
