Bonds returned to the field at SBC Park in San Francisco on Saturday and spent 30 minutes on light resistance and agility drills in the outfield, ESPN's Pedro Gomez reported.
A 10-minute workout covered the same areas Friday.
Bonds is awaiting the results of his regularly scheduled MRI, X-rays and blood test. The results will be checked by infectious disease specialist Robert Armstrong on Sunday.
Bonds is not expected to travel with the Giants for their upcoming six-game road trip through Minnesota and Detroit.
On his Web site Friday, Bonds said his rehab is going well.
"The rehab is coming along great. We are moving along at a nice pace and I'm only a few degrees from having full motion," Bonds wrote.
Bonds added in his journal that he is scheduled to get off antibiotics next week. Overall, he said he was encouraged with his progress.
"This week, I played catch on the field, did some resistance exercises and used my heavy bat to work on a few hand drills. Another good sign for me is that my stamina is coming back. I've been spending time cycling and when the time is right, I will be outside jogging. I feel that all the pieces are coming together at a good pace for me," Bonds wrote.
Giants trainer Stan Conte Conte said he was 99 percent sure Bonds would not travel with
the team on its road trip beginning Tuesday in Minnesota.
Manager Felipe Alou did not watch Bonds' latest workout but has

Alou also said he held out hope that Bonds could possibly return

Oakland beginning June 24, but admitted that option had not been
The Giants have struggled without Bonds, entering the day in
fourth place in the NL West and 14th in the league in runs scored.
That's a big reason why Alou's eyes lit up when he talked about
teaming Bonds with son Moises Alou in San Francisco's lineup.
"What a difference that would make -- those two guys
back-to-back," the manager said. "That's the wish of the year."
Bonds has had three operations on his right knee since Jan. 31,
the most recent on May 2 to drain fluid and examine an infection.
He has not played this season.
Bonds, who turns 41 on July 24, said in spring training he could
miss half the season or even the entire year, but has been more
optimistic recently about a return.
Bonds is third on the career home run list with 703, 11 behind
Babe Ruth and 52 from tying Hank Aaron's record. Bonds batted .362
last season with 45 homers and 101 RBI and walked a major
league-record 232 times on the way to his record seventh MVP award.
