ST. LOUIS -- Rookie Joe Kelly pitched into the seventh inning of what could be his final start before Jaime Garcia comes off the disabled list, and the St. Louis Cardinals got home runs from Matt Holliday and Jon Jay in an 8-2 victory over the Arizona Diamondbacks on Tuesday night.
Miguel Montero hit a two-run homer for the Diamondbacks, who have lost four of six to drop to .500. They are 0-4 against the Cardinals this season.
Ian Kennedy (10-10) made throwing errors on consecutive plays to help the Cardinals score two unearned runs in the seventh for a three-run cushion, and gave up both homers for a four-game total of eight long balls.
Kelly (3-5) gave up two runs in 6 1-3 innings and matched his career best with six strikeouts, lowering his ERA to 3.41 -- trailing only Kyle Lohse's 2.72 in the rotation.
