PEORIA, Ariz. -- Infielder Logan Forsythe has returned to San Diego to see a specialist about the plantar fasciitis in his right foot, manager Bud Black said Wednesday.
Forsythe, appearing in his first game since March 7, left Tuesday's game against the Giants after three innings when the pain in his foot became unbearable.
After the game, Black said there was a possibility that Forsythe could begin the season on the 15-day disabled list.
"He's really sore," Black said Wednesday.
With Chase Headley already set to miss much of April with a fractured tip of his left thumb, Forsythe would have likely been the Opening Day starter at third base.
As it stands now, veteran infielder Cody Ransom will make the roster and could likely start Opening Day on April 1 against the Mets.
Ransom, who was in the lineup at third base Wednesday, is hitting .250 this spring with four home runs and eight RBIs. He has played 80 career games at third base in parts of 10 Major League seasons.
The team could also use rookie Jedd Gyorko at third base and have Alexi Amarista play second base, but chances are Gyorko will remain at second base.
