Iglesias, who subsequently was left out of the lineup for three games, was thought to be sat due to a "manager's decision." DiSarcina said Tuesday it was so Iglesias could get his head together and refocus on the areas the Red Sox wanted him to emphasize when they sent him down. 

"Manager's decision is just that. It wasn't just one thing. We can sit here and talk about multiple things that were going on, but basically it came down to whatever John Farrell told him that he needed to do down here, he's not doing," DiSarcina explained. "I don't want to get all into that or expand on it, but I believe if somebody wants to know what's going on, they'll come down and they'll ask.

"They won't just make assumptions that he's a discipline problem. He's never been a discipline problem. He's on time. He does his work. He's a good teammate, all those things. But there's some things that need to be addressed."

Manager John Farrell said Wednesday that "players' personal goals sometimes don't align with team's goals." 

Farrell said Iglesias handled the initial demotion as a professional, but "I think as time has gone on, he’s kind of feeling like he should be in a big-league uniform. Yet, that time isn’t now."

Boston would love Iglesias to make the most of his time in the minors and Farrell implores him to utilize the opportunity he has. 

"You can say to a player, 'Hey man, it’s a raw deal. You’re getting a raw deal. You went up there, you did what you’re supposed to do and you exceeded expectations. But reality is reality. You’re here now. And we’re going to work to get you out of here. We’re here for you — the hitting coach, the pitching coach, myself, the trainer — we’re here to get you out of here. Use us.'"

Iglesias returned to the starting lineup for Pawtucket Wednesday. 

The issue stems from Iglesias failing to run out ground balls during Saturday's game. Iglesias has expressed frustration over Stephen Drew taking his place as the major-league club's shortstop. 

It's unclear when Iglesias will be back in the lineup.

Boston has been vague in discussing the reasons for Iglesias missing time, though he's not injured. Triple-A Pawtucket manager Gary DiSarcina declined to elaborate on Iglesias' issue, though manger John Farrell did have something to contribute. 

"In the reports from the Triple-A staff, they felt it was best he needed a couple days to regroup, kind of get back to what has allowed him to be a very good player," Farrell said. "He's experienced success. He's dealing with some things."

Iglesias, who hit .450 over six games for the Red Sox this season, is batting .235 over 68 at-bats for Pawtucket with three homers and 10 RBI.
