Gonzalez, a career .253 hitter over four Major League seasons, has played everywhere in the infield, but he has appeared mostly at second base (97 games) and shortstop (94 games).
Gonzalez, 27, is the player the Padres scouting heavily this spring in Florida, as they kept their eyes open for a utility infielder who could play shortstop.

Gonzalez hit .377 this spring in 53 at-bats.
"He's been a very steady utility guy the last two and a half seasons," Padres general manager Jed Hoyer said. "He can play all over. We like his glove and versatility.
"It became clear it was a position we wanted to upgrade."
The move also allows the Padres to do what they've intended all spring -- send shortstop Everth Cabrera to Triple-A Tucson to begin the season where he can play every day and continue to develop.
Hoyer said the Padres looked at "a half dozen guys" during Spring Training. They were linked to Gonzalez, Robert Andino of the Orioles and Luis Hernandez of the Mets as players they scouting heavily this spring.
Davis, a right-hander, was the Padres' 13th-round Draft pick in 2008. Davis went 14-3 last season between three Minor League stops.
