CHICAGO -- Neil Walker remained out of the lineup on Sunday, one day after being forced off Wrigley Field by soreness in his right side.
"That's all we can call it now, until it calms down and they can re-evaluate it," said Walker, who anticipates undergoing an MRI on Monday in Pittsburgh.
Walker held an ice pack to his right side and was also being given medication for what he said began as a "cramping feeling" early in Saturday's game against the Cubs. He went 0-for-2 and made one play in the field -- turning a line drive into a double play -- before leaving in the bottom of the fifth.
"I just felt something. I didn't know what it was, but I wanted to be careful," he said. "I've talked to a couple of the other guys who've had something similar, and they said you just have to give it a couple of days to calm down and go from there. I don't expect it to be anything extended."
"He's day to day and will be re-evaluated by our doctors," manager Clint Hurdle said.
The veteran Brandon Inge started Sunday's game at second base, and made a fine defensive play for the final out of the first inning.
Reid shows his stuff in short stint in bigs
CHICAGO -- It took a long time for right-hander Ryan Reid to get to the Major Leagues, and he ensured that his delayed presence was felt.
"He pitched multiple innings, what we were looking from him, and was very effective," manager Clint Hurdle said of Reid, who was optioned back to Triple-A Indianapolis on Sunday morning to clear roster space for A.J. Burnett, who came off the disabled list to start against the Cubs.
"It was great experience for [Reid], and his walkaway is that, I think, it will make him even better," Hurdle added. "He was looking for an opportunity for a fresh start, and he got it here. He was lost in the shuffle where he was."
Reid was a 2006 Draft choice by Tampa Bay, and he spent seven years in the Rays' Minor League system before signing with the Bucs last November as a Minor League free agent.
Reid spent a month with the Pirates following his early-June recall from Indianapolis, where he had posted an 0.52 ERA in 20 relief appearances. He appeared in seven games for the Bucs and posted a 1.64 ERA in 11 innings, allowing nine hits and two unintentional walks while striking out seven.
Burnett's return has bumped spot starter Jeanmar Gomez back to the bullpen which, even with Reid's departure, remains seven strong.
McCutchen hoping Martin joins All-Star crew
CHICAGO -- The day after being named, center fielder Andrew McCutchen was still glowing over his selection to a third consecutive National League All-Star team. But what has him especially stoked is taking one -- and maybe two -- of his nonpitching teammates with him to New York's Citi Field.
In 2011, pitchers Joel Hanrahan and Kevin Correia formed McCutchen's All-Star posse. Last summer only Hanrahan rode shotgun.
"Yeah, that's the nice thing: Some position players are coming with me," said McCutchen, referring to third baseman Pedro Alvarez.
But catcher Russell Martin is in line to join the NL squad if the Cardinals' Yadier Molina needs to skip next Tuesday's All-Star Game because of inflammation in his knee. Martin drew the most players' votes among NL catchers after Molina and the Giants' Buster Posey, who would start if Molina cannot.
McCutchen offers some advice for teammates Jeff Locke, Jason Grilli and Alvarez, all first-time All-Star selections: "Slow down and relish everything. It'll go by so fast."
McCutchen looks forward to experiencing his third All-Star Game perhaps as never before. The first one was too overwhelming, and last season's experience was intensified by his participation in the Home Run Derby.
"A once-in-a-lifetime experience," he said, "but once was enough. Everyone is watching you -- 40,000 in the park, millions on television, all the other players. You step up there and can't help but think, 'This'll be the only thing going on. Everyone's watching.' Tough to swing with all that pressure."
62: Stolen bases, entering Sunday's game, by the Pirates, who had 73 all of last season
"I remember sitting with him in 2010, the day after his injury, his leg dangling there, disconnected. I took a video of it. Last night we looked at it together, sharing that memory." -- Steve Grilli, father of Jason Grilli, reflecting on the injury to the right knee from which his son fought back to become a National League All-Star
• There's still a week to go before the annual midsummer break, but Starling Marte is already the first Pirates player in history to pair 27 steals with 32 extra-base hits before the All-Star Game.
• Sunday's start was Brandon Inge's second at second base since he started there five consecutive times upon his late April activation from the disabled list, while Neil Walker was recovering from a lacerated finger.
