Jonny Gomes saw plenty of Grady Sizemore across the field when Gomes was breaking in with Tampa Bay and Sizemore was going to All-Star Games with the Cleveland Indians in the mid-2000s.

"That guy, in his heyday, he was one of the big pieces that kicked off the 30-30 center-fielder guy," Gomes said before the Boston baseball writers' dinner on Thursday. "Now that's almost expected, which is tough. You look at the (Andrew) McCutchens, the (Mike) Trouts, the Curtis Grandersons. For my time, it was Grady."

Gomes has spent the winter working out at the same facility in Arizona where Sizemore has been working his way back to health. A three-time All-Star with the Indians, Sizemore saw his career derailed by a variety of knee and back injuries after his third straight top-12 Most Valuable Player finish in 2008. He underwent microfracture surgery on his left knee in 2010 and the same procedure on his right knee in 2012. He last played in a major-league game in 2011.

The Red Sox announced Wednesday night that they'd signed Sizemore to a one-year contract. He'll earn a $750,000 base salary and could earn up to $6 million if he meets incentives based mostly on playing time.

What Sizemore still has to offer, no one really knows. But he offers the Red Sox intriguing upside for relatively little risk -- and the Red Sox can offer him a situation where he can compete for a job in center field.
