Aceves reinstated, but appears to lose closer's role

ANAHEIM -- Alfredo Aceves rejoined the Red Sox following his three-game suspension on Tuesday after flying to the West Coast on his own. However, he no longer appears to be the team's closer.

Although manager Bobby Valentine hasn't made it official, it appears Andrew Bailey will pitch in that role for the rest of the season.

Aceves served as the setup guy and the closer on Tuesday, only because Valentine's bullpen was tapped out.

In the eighth, Aceves was masterful, mowing through the Angels. But in an all-too recurring theme of late, the righty faltered in the ninth inning, blowing the save in Boston's 6-5 walk-off loss to the Angels.

"What did I think of the ninth inning?" Valentine said. "I thought it was terrible. They scored two runs and beat us."

In his last 11 outings dating back to July 29, Aceves is 1-3 with an 8.56 ERA, allowing a .294 opponents' batting average. He has blown four of seven save opportunities over that time. For the season, Aceves is 2-9 with a 4.76 ERA. He is 25-for-33 in save opportunities.

Meanwhile, Bailey has come back from right thumb surgery and thrived, posting a 1.69 ERA in his first seven games.

One tell-tale sign that Aceves is no longer the closer is the fact he warmed up as early as the sixth inning on Tuesday.

"I'm not saying that was his role tonight for a save. He was the only guy available to pitch," Valentine said. "Bailey's been in the ninth inning the last few games. [Aceves] was up in the sixth inning tonight."

Aceves did not make himself available to the media after the game, taking a call on his cellphone that was still going on as he walked out of the clubhouse.

Before the game, in a brief interview, Aceves chose not to show remorse for his suspension.

"The past is the past," Aceves said. "I'm here to play baseball."

Aceves was suspended for disciplinary reasons. It's believed he had a tirade in Valentine's office on Friday after the manager went with Bailey in a save situation that night.

"It's all over," Valentine said. "I'm excited about him possibly coming back and helping us win a game -- or two or three."

At times during the interview, Aceves got testy.

"Please ask me about baseball. OK? Can you hear that?" Aceves said. "I'm going to answer your question, but that's personal. That's personal stuff for the team. What happened with the team stays in the team."

Valentine didn't divulge much more.

"We talked in here for a half hour and another 20 minutes with the coaches," Valentine said.

To make room for Aceves on the roster, the Red Sox placed lefty Franklin Morales on the disabled list with left shoulder fatigue.

Iglesias excited to get a chance down the stretch

ANAHEIM -- One of the most appealing things about watching the Red Sox down the stretch could be the chance to see Jose Iglesias play shortstop.

Talked about for three years as the team's potential shortstop of the future, Iglesias now has a chance to show what he can do.

Iglesias was on the bench for the first three days of his most recent promotion, but he batted eighth and started at shortstop for manager Bobby Valentine on Tuesday night.

This was the second Major League start for Iglesias, and first since May 11, 2011.

"There's really no reason to have Iglesias here if he doesn't get some action," said Valentine. "He'll shake a little of the three-day rust. I'm anxious to see him play."

Iglesias was in the running to be Boston's starting shortstop back in Spring Training, but he lost that competition late in camp to Mike Aviles.

"This is a great opportunity to be here with the team and try to help in anything that I can," Iglesias said.

The two things that have been the biggest obstacles during the development of Iglesias have been consistency on offense and staying healthy.

The hitting has come around of late. In August, Iglesias hit .329 with five doubles, nine walks and 14 runs at Triple-A Pawtucket.

"Just see the ball, recognize the ball, drive the ball," Iglesias said. "I think I've done a pretty good job this year. I was healthy. I was able to do everything that I can in the field, and fortunately I did."

Ryan Lavarnway, another possible cornerstone for the Red Sox in the future, batted cleanup and started at catcher on Tuesday.

Stewart to make Red Sox debut Wednesday night

ANAHEIM -- There was yet another new face in Boston's clubhouse on Tuesday. Right-hander Zach Stewart, who was acquired back in June from the White Sox in the Kevin Youkilis trade, will start for the Red Sox on Wednesday night.

With Josh Beckett traded over the weekend and Franklin Morales on the disabled list, a spot opened, and the Red Sox will use it to get a look at Stewart.

The 25-year-old Stewart pitched in 18 games for the White Sox this season, posting a 6.00 ERA. Just one of those outings was a start. The Red Sox hope to develop him into a starting pitcher.

Stewart has made 11 starts for Triple-A Pawtucket, going 3-5 with a 3.94 ERA. Over 59 1/3 innings, he had 14 walks and 52 strikeouts while holding opponents to a .252 average.

"I felt like I started off strong," Stewart said. "I had a couple of rough outings in the middle, and I've been doing well lately. It's one of those things. It's just starting. It's how it always is, just try to stay as even-keeled as possible."

The Red Sox will now get a chance to see what they have in Stewart.

"There's very little I can say about him other than the reports I've read, which tell me he's a good competitive athlete with a good sinker, not afraid of contact, likes to play the game of baseball," manager Bobby Valentine said. "We'll be excited to have him out there."

Youkilis wasn't the first big-name player Stewart has been traded for. Back in 2009, he was traded along with Edwin Encarnacion from the Reds to the Blue Jays for Scott Rolen. The Blue Jays packaged him with Jason Frasor in a 2011 trade to the White Sox for Edwin Jackson and Mark Teahen.

"There's always a silver lining to it, because somebody wants you and somebody is giving up something to come get you," Stewart said. "It was a big trade. To give up someone like Youkilis and what he brings to the table and what caliber a player he is meant a lot to me to come over here that they thought that much of me to give up a guy like that."

Shoulder inflammation lands Morales on DL

ANAHEIM -- There has been a noticeable downturn in the performance of left-hander Franklin Morales of late, and now it appears there could be a reason why.

Morales was placed on the 15-day disabled list before Tuesday's game against the Angels with left shoulder inflammation.

Over his last two starts, Morales pitched eight innings while giving up 12 hits and 11 runs, seven of which were earned.

It is unclear when he will return.

"It was a little cranky the other day, and at this time of the year, I just didn't think there was any reason to be anything but cautious," said manager Bobby Valentine.

Morales has pitched in 37 games this season, going 3-4 with a 3.77 ERA. He has started nine games, going 3-3 with a 4.14 ERA while holding opponents to a .225 average.
