CINCINNATI—Kerry Wood’s throwing error let two runs score and Chris Heisey followed with a tiebreaking sacrifice fly in the eighth inning that sent the Cincinnati Reds over the very sloppy Cubs 7-5 on a wet Tuesday night. The Cubs self-destructed with four errors in a steady rain. All seven of Cincinnati’s runs were unearned.Wood (1-3) threw wide of third while trying to get a forceout on Ryan Hanigan’s sacrifice bunt, allowing the catcher to go all the way to third base while the tying runs scored. Heisey put the Reds ahead and Joey Votto added an RBI double.The Reds won for the 11th time in 13 games, sweeping the two-game series.Bill Bray (1-0) got the win by retiring the one batter he faced in the eighth. Nick Masset pitched the ninth for his first save in four tries, filling in because closer Francisco Cordero had pitched the last four days.While the Reds reached a season-high at eight games over .500, the Cubs fell to a new low at 17-23, collapsing for the second game in a row. Manager Mike Quade called a closed-door meeting after the Cubs blew a four-run lead and lost 7-4 Monday night. A day later, the Cubs again fell apart in tough conditions — constant rain and 50 degrees.Carlos Pena put the Cubs up with a three-run homer in the first inning off Edinson Volquez, who can’t seem to get through the opening inning without problems. The right-hander has given up runs in six of his nine opening innings. Volquez has allowed 17 earned runs in the first inning, 13 in all other innings combined.It was Pena’s fifth homer and his second in two games.Just like on Monday night, the Cubs gave it away. Starter Matt Garza intentionally walked Ramon Hernandez to load the bases with two outs in the fourth, bringing up Volquez, who doesn’t have a hit this season. Volquez hit a grounder that deflected off Pena’s glove at first for an error. Garza got the ball and compounded the problem by throwing wildly to home, letting in two more runs.The Cubs regained the lead when Jose Arredondo forced home a run with a bases-loaded walk in the seventh. Outfielder Tony Campana, called up before the game, doubled home a run in the eighth in his first big league at-bat for a 7-5 lead. Wood then threw it away.Marlon Byrd matched his career high by striking out four times, ending a 16-game hitting streak that was the best of his career.

NOTES—The Cubs sent Tyler Colvin (.113 batting average) to the minors to work out of his funk and called up Campana from Triple-A Iowa. They also swapped relievers, replacing Marcos Mateo with Scott Maine. … Campana grew up in southwest Ohio and attended the University of Cincinnati. He got 50 tickets for family and friends, who loudly cheered his eighth-inning double. … The Reds activated 3B Juan Francisco (strained left calf) off the 15-day DL and optioned him to Triple-A Louisville.
