Outfielder Bryce Harper and shortstop Ian Desmond are both dealing with chest colds. Harper is playing on Thursday but will have Friday off. He could return as soon as Saturday.

Desmond, who cut a finger on Wednesday with a pre-game grounder, was sent home on Thursday morning to rest from the cold. He wouldn’t have played anyway because of his finger, Manager Matt Williams said.

●  Left-handed reliever Michael Gonzalez, signed last week to a minor-league deal, appeared in a game for the first time on Wednesday but on the minor-league side. He faced four batters, all right-handers.

Gonzalez believes he only needs two to three weeks, essentially five or six innings, to get ready for the season. Gonzalez is scheduled to make his Grapefruit League debut on Friday against the Detroit Tigers in Lakeland.

“I think we’re just gonna [go] based on how I’m feeling,” he said. “It doesn’t take much for me to get ready. I’m good with five or six, man, and we’re right on pace. … I thought I’d be experiencing a little bit of soreness that first outing but I didn’t feel any [Thursday] and feel good [Friday].”

●  Left-hander Sammy Solis hasn’t pitched since March 2 because of back spasms. After rest, Solis was scheduled to throw a bullpen session on Thursday morning. He said is unsure what sparked the discomfort, but it is much improved.

“It’s great,” he said. “Feels good now.”

●  Right-hander Ross Ohlendorf, who has been dealing with back stiffness, threw a bullpen session on Thursday morning. “I feel good,” he said.
