The Reds won for only the second time in 11 games since the All-Star break. The offense has been the biggest problem, scoring only 20 runs — by far the fewest in the majors over that span.
Leake (8-9) had a single off the glove of diving third baseman Martin Prado that drove in a run in the second off Trevor Cahill (1-8), who has yet to win as a starter this season. Todd Frazier and Brayan Pena had RBI singles off Cahill, who fell to 0-6 in seven starts this season.
Aroldis Chapman pitched the ninth for 23rd save. He extended his streak of at least one strikeout in 45 consecutive appearances, a major league record for a reliever.
