Chris Heisey hit his first grand slam and Devin Mesoraco homered and drove in career high-tying four runs as the Cincinnati Reds took advantage of Tampa Bay's depleted pitching staff for a 12-4 victory on Sunday.

The Reds' best offensive showing of the season featured Mesoraco's three-run homer, Joey Votto's two-run shot and Heisey's pinch-hit slam in the eighth. Jay Bruce doubled, walked four times and scored four runs.

Zack Cozart got it going with a bases-loaded double off Cesar Ramos (0-1), making his first start of the season because of injuries.

The Reds salvaged the final game of their interleague series but remained in last place in the NL Central at 4-8.

Left-hander Tony Cingrani (1-1) gave up five hits in 6 1-3 innings. Ben Zobrist homered from both sides of the plate, hitting two-run shots off Cingrani and right-hander Nick Christiani.
