However, Iglesias will go back to the Minors perhaps as early as next week, as Stephen Drew could return from his concussion by Monday's home opener.
"We're certainly not going to take away from what Jose's done, but we signed a premium guy in the offseason to be our starting shortstop and we're not going to look at an injury to cause him to lose his job," said Red Sox manager John Farrell.
The good news is that Iglesias looks like a far more polished hitter than the one who finished last season in a prolonged slump.
"I think the biggest change was in my mind," said Iglesias. "I put in the hard work this offseason to be in this position today and to help this team win some ballgames. I feel pretty good, like I said."
As far as what happens once Drew returns to action, Iglesias knows he can't control that.
"No, I haven't heard anything," Iglesias said. "I'm just focused on playing the game one day at a time and be in the best position possible to help this team win some ballgames."
