Due to suspension, Aceves can't fly on team plane

BOSTON -- Alfredo Aceves will have to find his own ride to the West Coast.

The Red Sox's closer served the last of the team's three-game suspension Monday, against the Royals at Fenway Park. The Sox leave for Anaheim afterward, but Aceves won't be on the team plane.

"On the same plane, no," manager Bobby Valentine said. "I expect him to be in California though."

Aceves was suspended Saturday for throwing a fit when Andrew Bailey was asked to close out a 4-3 win over Kansas City on Friday. With Bailey hurt most of the season, Aceves has served as Boston's closer. But the night before Bailey recorded that save, Aceves allowed five runs in the ninth and 10th innings.

"Like I said, it just deals with being responsible for your actions and understanding that all actions have consequence," Valentine said Monday. "It's just a simple rule. Remember, I don't have a lot of rules, but one of the rules I stated early on is that you don't do anything to embarrass yourself, your teammates or your organization."

Valentine hasn't talked to Aceves since the suspension was handed down Saturday, although Valentine said there had been communication with Aceves elsewhere. Aceves hasn't been at the park, to Valentine's knowledge.

Valentine still hasn't declared a closer for the rest of the season, but he expects Aceves to be ready to go if called upon in Anaheim.

"I haven't made that determination," Valentine said of Bailey closing. "He's in that role today, though."

Ortiz lands back on DL, hopes to return this season

BOSTON -- David Ortiz isn't calling it a season yet.

The Red Sox's designated hitter went back on the 15-day disabled list Monday because of his bothersome right Achilles, but he intends to return this season. He was slated to receive a platelet-rich plasma (PRP) injection Monday and will fly to the West Coast separately from the team.

"That helps you heal a little faster," Ortiz said. "The doctor said there's a 60-70 percent chance of that to help. I had that done before, and I believe in it big time. The thing is that we didn't get it done before because we thought it wasn't needed in my case, but at this stage, this point, I've got to get through it. When I heard them talking about it this morning, it kind of made me happy, because the one thing I was listening about before was hanging it up for the rest of the season, which is something that came into my head a little bit, just for being out with no hope [of coming back]. But the doctor brought that up and I want to give it a try."

With the Red Sox's playoff chances fading, Ortiz likely won't be back on the field again unless the circumstances are ideal for him, but the plan is to try. He's a free agent again this year with his sights set on a multiyear deal, and he has the numbers for one: a .318 average with 23 home runs and a .611 slugging percentage.

Ortiz has played in just one game since July 16. On Friday, in a 4-3 win over the Royals, he rattled off two hits, one a double. It was legging out the double that showed him he still wasn't right.

"If everyone felt, if he had that desire and the medical staff thought that it was the best thing for his career, that would definitely be done," manager Bobby Valentine said of shutting Ortiz down. "But with the meeting of the minds [we held Monday], with David wanting to get back in uniform and the medical staff believing that there's a chance that he could, we figured that's the best way to go."

Outfielder Ryan Kalish was recalled from Triple-A Pawtucket to take Ortiz's spot on the active roster. Right-hander Pedro Beato was optioned to Pawtucket to make room for Monday's starter, Daisuke Matsuzaka, who came off the DL.

The decision for Ortiz to do PRP was in place of doing shockwave treatment immediately. He will still undergo that form of therapy, he said, but to do it now would definitively mean ending his season.

"It was going to be my next step, which is something that you've got to be out of activity, baseball activity, for four to five weeks," Ortiz said. "That's why, in my mind, I was like that's what we've got left for the season, so I guess if I'm going to go and have that done, it's going to be a wrap. But we came out with some ideas, different ideas today, and that's what we're going to go and do now, the next couple days, and if I'm good to go, I'm good to go. I'll be happy to come back and play."

Ortiz again said surgery isn't necessary as things stand now. He also reinforced that he wants to be with the Red Sox next year, accounting for the team's makeover.

"Through the years, I always keep telling everyone how important it is for me to be part of this organization," Ortiz said. "This is what I know and this is something I want to be part of. I know we've been having a lot of issues through the years, but I always try to be honest with you guys. I know how hard sometimes it can be to perform at the highest level here. Things will get better. I think a lot of it has to do with the way the team is playing at the time. When things are going good, you don't hear any of it. Hopefully for the years to come, we start performing better and all the negativity and stuff just goes away."

Sox not sure who'll get promoted in September

BOSTON -- Rosters expand to 40 Saturday when the Red Sox are in Oakland, but manager Bobby Valentine hasn't had much time to go over potential new faces.

"I talked with [assistant general manager Brian O'Halloran] just generally about a week ago," Valentine said. "What it should look like. No names."

The Triple-A PawSox had a half-game lead for the International League's only Wild Card spot entering Monday, at 73-63 in the 140-game schedule. The Lehigh Valley IronPigs are on their heels, with the next three closest teams ranging between four and 5 1/2 games back.

The International League regular season runs through Sept. 3, and if the PawSox make the playoffs, the organization may elect to keep most of that team together until the run is over.

Jose Iglesias, Pawtucket's shortstop this season, has been in the Majors for three days, but he hasn't started yet. Valentine said the rest could actually do Iglesias good, despite the common thought that a developing player needs regular time in the field.

"He's going to try to help us. He's here to help us win games when needed," Valentine said. "Probably needed the rest."
