Backup catcher Michael McKenry had the first two-homer game of his four-year major league career and Starling Marte hit a tiebreaking two-run drive in a six-run eighth inning Sunday, helping the Pittsburgh Pirates rally from a five-run deficit for a 10-7 win over the Cincinnati Reds .
Cincinnati has lost five straight, its longest slide since last Aug. 5-9. The Pirates swept the Reds for the first time since April 16-18, 2010, in Pittsburgh.
Pittsburgh trailed 5-0 when McKenry homered off Mat Latos leading off the seventh. Travis Snider 's RBI double off the top of the right-field wall - upheld after a video review - chased Latos, Andrew McCutchen doubled in a run against Logan Ondrusek and pinch-hitter Gaby Sanchez had an RBI single off Manny Parra .
