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.
