SCOTTSDALE, Ariz. -- Infielder-outfielder Mark DeRosa and second baseman Freddy Sanchez reported progress with their respective injuries as they engaged in baseball-related activities Monday.

DeRosa tested his surgically repaired left wrist by taking batting practice for the first time since he played his final game of the 2009 season -- Game 3 of the National League Division Series for St. Louis against Los Angeles. He swung at pitches thrown by a coach in a batting cage.

DeRosa won't participate fully in Tuesday's initial full-squad workout, but he believes that he'll be fit to play in the Giants' Cactus League opener March 3 against Seattle.

"As long as I don't regress or get sore from starting up swinging, I would feel like I'd be ready," he said.

Braving the rain, Sanchez tested his surgically repaired left shoulder and left knee by playing catch, running and performing agility drills.

"It feels good just to be outside again," said Sanchez, who had been exercising indoors. "I haven't seen outside in -- it feels like a year.

Sanchez said that though he has been running for about a week, "this was the first time we picked it up intensity-wise."

Sanchez, who's not expected to be ready for the April 5 regular-season opener at Houston, repeated his hopes that he'll be able to start taking ground balls in a week to 10 days.

"This is the best my shoulder and knee have felt since I got hurt," he said. "It's good to know I'm making progress."
