CHICAGO -- Chris Heisey will be placed on the 15-day disabled list on Sunday, and the Reds will likely call up outfielder Dave Sappelt from Triple-A Louisville.

Heisey strained his oblique while taking batting practice in Houston earlier in the week.

Sappelt was selected by the Reds in the ninth round of the 2008 First-Year Player Draft. In 74 games for Louisville, he is batting .313 with 16 doubles, seven home runs and 29 RBIs.

Phillips tips his hat to Cubs' Campana

CHICAGO -- On paper these two players have nothing in common. One has played in almost 1,000 games over 10 seasons. The other hasn't even been in the Majors for half a season.

Reds second baseman Brandon Phillips and Cubs outfielder Tony Campana may be at two completely different stages in their respective careers, but they share a mutual respect.

Phillips and Campana had a back-and-forth kind of day on Friday, each robbing the other of extra-base hits in the Reds' 4-3 loss to the Cubs.

"It's the name of the game," Phillips said. "All you can really do is just tip your [cap]."

It all started in the fifth, when Campana lined a shot right at Phillips. If Phillips had been standing a few feet to the right or left, the ball surely would have sailed into the outfield, and the speedy rookie likely would have stretched it into a double.

Campana exacted his revenge in the seventh, after Joey Votto walked with one out. In a one-run ball game, Phillips hit a towering fly ball to deep center. Campana raced back and jumped backward into the ivy, making the catch and robbing Philips of an RBI double.

"He made a great play," Phillips said. "I got him earlier in the game. I joked with him at second base, saying, 'Thanks for getting me back, man.' ... He just busted out laughing and was like, 'Yeah, I had to get you.'"

Aroldis' hitless streak ends at 10 1/3 innings

CHICAGO -- The Reds lost more than just a 4-3 decision to the Cubs on Friday.

Starlin Castro's two-out single in the eighth inning ended reliever Aroldis Chapman's hitless streak at 10 1/3 innings.

"The main thing is, he's throwing strikes -- he's throwing quality strikes," manager Dusty Baker said. "We've got to pace him, his workload. He's doing great. He had that one period where he couldn't find the plate, so he went down to Triple-A and Double-A and got it straight."

That stretch was the longest single-season hitless streak by a Reds reliever since Chuck McElroy's 11 1/3-inning run from April 25 to May 17, 1994.

In 34 appearances this season, Chapman is 2-0 with a 3.62 ERA, giving up 11 hits in 32 1/3 innings.
