DeRosa missed his seventh game Sunday with an aggravated nerve in his left wrist, which is also accompanied by numbness in his two of his fingers.
"He's doing a few things today and we will evaluate where we are with him then," Giants' manager Bruce Bochy said before Sunday's series finale with the Houston Astros. "The tendinitis has calmed down but he still has some numbness."
DeRosa received further treatment and will try to hit off a batting tee after taking a few dry swings.
"He hasn't played in awhile and it's up to us to go ahead and give him a few more days or whether we think he's ready," Bochy said. "We have to be smart about this and could just give him a few more days to make sure."
The Giants open a weeklong road trip, with no days off, in San Diego on Monday night. Bochy said that could factor into the decision concerning DeRosa's immediate future.
