Chapman still working on command issues

LOS ANGELES -- It doesn't take a trained eye to see that Reds lefty reliever Aroldis Chapman's rehab assignment statistics aren't very good. But Sunday's third outing for Double-A Carolina was an improvement with two scoreless and hitless innings with two walks and three strikeouts. He threw 20 pitches, including 11 strikes.

In his three games at Carolina, Chapman has a 19.29 ERA with five runs, five hits and five walks over 4 1/3 innings.

"We still feel like we're going in the right direction but there still have been some bouts with command," Reds pitching coach Bryan Price said. "This kid doesn't need to be a guy that walks three batters or less per nine innings or that type of ratio. He'll probably settle into his command the more he pitches. It's been mixed reviews. He's thrown the ball very well at times. He's put together some good sequences. He's done very well in stretches but there are periods of time he hasn't done well."

Chapman, who has been on the disabled list since May 16 with left shoulder inflammation, also had a 13.50 ERA in three rehab games with Triple-A Louisville. He has nine days left in the maximum 30-day rehab assignment.

If the Reds don't feel Chapman is ready, they could always option him to the Minors to give him more time. Whether that choice is on the table is unknown.

"We haven't talked about that. I'm not going to volunteer my thoughts on that," Price said. "We'll discuss it once we get back off this road trip and see where he is. I've been in touch with [Carolina pitching coach] Tom Brown, who is doing a nice job working with him there. The goal is to get him back to throwing the ball crisply with some consistency. We'll certainly be looking at his performance in Double-A as an indicator of how sharp he is and add it to the equation when we decide."

Rolen out of Reds lineup with sore foot

LOS ANGELES -- The slow walk Scott Rolen took toward the Reds clubhouse hours before Monday's game told part of the story. Later, the wrap around his left foot told the rest.

Rolen did not start at third base for the Reds vs. the Dodgers. He was still smarting quite a bit after he fouled a ball off his foot during Sunday night's game vs. the Giants.

"I'm not dead and it's not broken," said Rolen, who is day to day. "But it happened in the second inning yesterday and I had to stand out on it for three hours. I'll be pretty hobbling on it."

Rolen had played the last four games at San Francisco after he missed the four before that with a throat illness. He was 3-for-14 in the series, including a RBI double Sunday, and is batting .240 with two home runs and 22 RBIs this season.

Miguel Cairo started in Rolen's place Monday.

Walks proving nettlesome for Reds bullpen

LOS ANGELES -- The Reds bullpen led the National League in innings pitched entering Monday, but also came in leading the Majors in walks allowed. Jose Arredondo's four-pitch leadoff walk to No. 8 hitter Chris Stewart led to two runs and him getting the loss Sunday vs. the Giants.

Arredondo has walked the first batter in each of his previous three appearances and lost the last two.

"It's a concern especially when it's the leadoff batter," Reds manager Dusty Baker said. "We've been doing that quite often lately. It's especially tough when it's the latter part of the ballgame and Bryan [Price, Reds pitching coach] has been addressing this.

"A lot of our guys are walking the first guy and after that are settling down. A lot of times, the sparks have already started the fire."

Reds ink 14 Draft picks, including third-rounder

LOS ANGELES -- The Reds announced Monday the signing of third-round pick Tony Cingrani, a left-handed reliever out of Rice University. Cingrani had 12 saves in 32 relief appearances this season while posting a 1.74 ERA.

Cingrani was the highest pick out of 14 signings from the 2011 First-Year Player Draft the Reds announced Monday, including fourth-round right-handed pitcher Kyle McMyne out of Villanova. McMyne was a starting pitcher in college but is projected to be a reliever.

Also signed was third baseman Sean Buckley (sixth round), the son of Reds amateur scouting director Chris Buckley. After Buckley, the organization inked pitcher James Allen (seventh round), outfielder Jon Matthews (eighth round), pitchers Ronald Pinckard (10th round), James Moran (18th round), Chris Joyce (19th round), Daniel Jensen (20th round) and Carlos Gonzalez (21st round), first baseman Nicholas O'Shea (24th round), pitcher Justice French (25th round), second baseman Juan Perez (26th round), pitcher Eric Alessio (49th round) and undrafted free agent and shortstop Phillips Bauer.

Worth noting

• Injured reliever Sam LeCure (right forearm) is slated to throw two innings Tuesday in his next rehab assignment outing for Triple-A Louisville.

• The Reds announced that Paul McCartney would perform the first standalone concert in the history of Great American Ball Park on Aug. 4. The "On the Run" tour will be McCartney's first stop in Cincinnati since 1993, at Riverfront Stadium.

Tickets for the show go on sale Friday at noon ET and can be purchased at Reds.com.
