With three callups, Reds have 11-man bullpen

CINCINNATI -- The Reds made three more September callups on Tuesday, recalling pitchers Todd Redmond and Pedro Villarreal from Triple-A Louisville and selecting the contract of pitcher Tony Cingrani from Double-A Pensacola.

With the expanded rosters, Cincinnati has an 11-man bullpen. How some of the rookies will be worked into service remains to be seen.

"I've got my eyes open on how guys are handling this or paying attention and working hard, if they throw strikes in the 'pen and their background and record," Reds manager Dusty Baker said. "We are not here for no tryout camp. We're here to win the pennant. We haven't won the pennant yet."

Cingrani, a fast rising prospect in the system, was 10-4 with a 1.73 ERA in 26 games, including 25 starts, for Pensacola and Class A Bakersfield. His ERA was second-lowest among all Minor League pitchers with at least 100 innings.

Villarreal began the season at Pensacola before his May promotion to Louisville. Combined, he was 4-14 with a 4.36 ERA in 26 starts over 148 2/3 innings.

This is Redmond's fourth big league promotion of the season. His lone appearance for the Reds came when he started the second game of an Aug. 18 doubleheader against the Cubs. Redmond lasted only 3 1/3 innings and allowed four runs and seven hits with five walks.

To clear space on the 40-man roster, the Reds sent outright to Louisville infielder Chris Valaika and reliever Jordan Smith. Both have big league experience with Cincinnati, but neither were called up in 2012. Valaika batted only .223 in 85 games, while Smith was 3-3 with a 4.61 ERA and 13 saves in 51 games for the Bats.

Chapman again MLB's Delivery Man of Month

CINCINNATI -- For the second straight month, Reds closer Aroldis Chapman was named Major League Baseball's Delivery Man of the Month for August. The award recognizes the most outstanding relief pitcher during each month of the regular season, and is voted on by a panel from MLB.

Chapman, who entered Tuesday 5-4 with a 1.25 ERA and 34 saves in 61 games this season, was 1-0 with a 0.68 ERA and a league-best 11 saves over 13 appearances last month. He allowed eight hits and two walks with 18 strikeouts.

The only previous winner of back-to-back awards was Rafael Soriano of the Rays in July and August 2010.

Chapman, who has not blown a save since June 24 against the Twins, has converted 26 in a row to establish a new club single-season record.

Baker lauds defensive efforts of Cozart, Frazier

CINCINNATI -- Lost in the shuffle during a lackluster 4-2 Reds defeat against the Phillies on Monday afternoon was some fine defensive work by two rookies.

In the second inning, shortstop Zack Cozart adroitly snared a low-flying laser on the short hop from Domonic Brown for a groundout. In the third inning, first baseman Todd Frazier made a diving stop on a grounder to his right. After the ball briefly got away, he managed to flip it to pitcher Johnny Cueto covering the bag to rob speedy Juan Pierre of a hit.

"Cozy is 'steady Eddie.' Frazier is working," Reds manager Dusty Baker said. "That was a problem in the Minor Leagues. He didn't really have one position. His strength was the fact he could play a lot of positions. You like a young player to eventually settle on one position. That's what's going to make him better."

Worth noting

• The Reds' home attendance is expected to reach the two-million mark on Tuesday, their 68th home game of 2012. It would be the fastest to two million in Great American Ball Park history, and break the record of crossing two million by the 69th game during the 2003 inaugural season.

• Before Tuesday's game, Cincinnati Bengals quarterback Andy Dalton threw a ceremonial pitch. Dalton's catcher was his primary wide receiver, A.J. Green.
