"It was sharp, he looked really good from the side," Maddon said. "I couldn't tell exactly the pitches from the side, but the reaction from the swing tells a lot, so I'd like to believe he can really build off of that."
Farnsworth started the season on the 60-day disabled list with a strained elbow, and outside of the game against New York, he hasn't allowed a run.
Outfielder Sam Fuld also joined Farnsworth on the disabled list to start the year because of right wrist surgery, but he is in the middle of a rehab assignment with Class A Charlotte. He will play seven innings in the outfield Saturday in his fifth and final game with the team that has seen him go 1-for-10 at the plate so far.
Fuld will then head to Triple-A Durham to continue his rehab Monday, when he will play another seven innings in the field.
"The biggest thing for us is that he doesn't feel his timing is very good at the plate yet," Maddon said. "But he's feeling physically really good, so that's going well."
Fellow outfielder Matt Joyce is set to make a rehab start Sunday for Charlotte at Daytona Beach and is scheduled to stay there until Tuesday, when he will be reevaluated. Maddon said he has the potential to return Wednesday or Thursday. He will play six innings in the field.
"It's always one day at a time," Maddon said. "Tomorrow will tell a lot and then how he reacts the next day."
Hideki Matsui has also been banged up as of late, nursing left hamstring tightness that has not required him to head to the DL. The 38-year-old has been available to pinch-hit, and Maddon said he is getting closer to being able to play defensively.
"The ball is really coming off his bat a lot hotter [in batting practice], which tells me that his bottom half is feeling better because he's really a bottom-half-oriented hitter," Maddon said.
