GLENDALE, Ariz. -- Charlie Tilson will spend another three weeks in a walking boot and is likely out until at least the end of May.
The White Sox outfielder has been wearing the boot ever since he re-aggravated a stress reaction in his right foot earlier this month. Tilson is also rehabbing a torn hamstring that required surgery last August and ended his 2016 season early.
The White Sox later downed the San Francisco Giants 4-3 at Camelback Ranch. Catcher Roberto Pena had a two-out, two-run single in the ninth.
“It’s likely going to be a little bit of a process from there,” Tilson said. “One of those things you have to listen to your body. Like I said, it may take more time than I would like. But the ultimate goal is to be sustainable and get myself back to where I need to be.”
The White Sox top options for center field remain veteran Peter Bourjos and prospect Jacob May. They also could use Leury Garcia in center, manager Rick Renteria said.
Center field is one of several open roster battles with only three full days to go in camp. The team is off on Thursday before playing a pair of exhibition games at Milwaukee on Friday and Saturday.
“We’ll figure it out, and it could be in the next couple of days,” Renteria said. “We just have to allow it to play out and then make a determination at that point.”
The White Sox also have two spots up for grabs in the back of the bullpen. Michael Ynoa, who is out of options, non-roster invitees Anthony Swarzak, Cory Luebke and Matt Purke, and rookie Zack Burdi are vying for jobs. Rookie Juan Minaya is likely to start the season on the disabled list.
Rule 5 draftee Dylan Covey, who pitched 3 2/3 scoreless innings on Saturday, could figure into the team’s plans even more if Carlos Rodon starts the season on the disabled list. Covey is expected to start for the White Sox on Wednesday against the San Diego Padres.
Sunday’s starter James Shields said he’s ready for the regular season after throwing five innings. Shields allowed three earned runs and eight hits, walked three and struck out two.
He finished the Cactus League with a 3.45 ERA in 15 2/3 innings.
“Overall I felt good and I’m ready to move on,” Shields said. “These last couple outings I’ve been trying to work on my two-seam fastball. Today it was a little erratic, but overall felt pretty good.”
Nate Jones struck out two in a scoreless inning pitched. David Robertson, Blake Smith and Dan Jennings also pitched a scoreless inning.
Jose Abreu doubled and walked in four trips. Melky Cabrera singled twice in three trips.
