DETROIT -- Lefty Jonathon Niese checked Detroit on five hits over six innings while Matt Joyce, getting a chance to start because Pittsburgh needed a designated hitter in an American League park, keyed two early rallies with a single plus a double Monday to help the Pirates to a 7-4 victory over the Tigers.
Niese gave up a pair of solo home runs to J.D. Martinez, his first, in the fifth and Nick Castellanos, also his first, in the second while becoming the second softer-tossing southpaw in two games to beat Detroit.
CC Sabathia, who no longer hits 90 mph, earned a win over the Tigers for the New York Yankees on Saturday.
