JUPITER, Fla. -- Ahead of the Marlins' first workout earlier this week, general manager Kim Ng acknowledged that one of the more difficult aspects of the offseason was keeping tabs on rehabbing players, as club officials were unable to contact them during the lockout.

"We had some injuries last year, and guys at the end of the season who had surgery, but we got through it," Ng said. "We were receiving reports through the offseason, but of course it's never the same as having your own eyes [on them]."

Following is an update on the four main Marlins who spent the winter rehabbing.

3B Brian Anderson (left shoulder)

Anderson had a disjointed 2021 season that included two stints on the 60-day injured list, leading to surgery to repair his left shoulder capsule on Sept. 14. Over the offseason, Anderson rehabbed five days a week in South Florida with former Marlins physical therapist Ron Yacoub, who helped José Fernández following Tommy John surgery. By early January, Anderson felt like himself.

The 28-year-old also had the benefit of seeing teammates Sandy Alcantara, Pablo López and Anthony Bender throw at the facility, and he credits that for helping him come back ready for camp.

"The only thing that is a question is just once I dive and land on it again, and that's not something I'm going to plan on doing here soon," Anderson said. "But I have no worries about it right now. I haven't really thought about my shoulder much at all. I'm just excited to play baseball again."

1B Jesús Aguilar (left knee)

Aguilar was on pace for a 100-RBI season in 2021 before experiencing inflammation in his knee in early September. He underwent arthroscopic surgery on Sept. 27 and began rehabbing in Miami before moving to Orlando for two months. It was around that time he could start to run and perform normal baseball activities.

"I'm close," Aguilar said. "I just don't want to force, especially now it's a short Spring Training. So we've got to be smart. We've got to do things in the right way. I'll be 100 percent for the season."

Manager Don Mattingly reiterated that sentiment, saying that Aguilar will "not be pushed too hard early."

"The lockout kind of helps them," Mattingly said. "A little more time to kind of continue to do some things without getting into camp. That kind of brought them into camp as full go instead of them coming into camp like, 'OK, we've got to watch these guys a little bit.'"

1B Garrett Cooper (small tear in non-throwing arm)

Though Cooper underwent Tommy John surgery on Aug. 10 after his left arm bent awkwardly as he tried to handle a throw on July 18, his offseason was relatively the same -- just with more physical therapy. His rehab lasted until the end of December, and an invaluable resource came in the form of Phillies first baseman Rhys Hoskins, who went through the same recovery as a position player in 2020. The two had gotten to know each other while competing in the Minors, and Hoskins assured Cooper he could ask him questions throughout the process.

"He's like, 'I went through everything that you went through, so if you have any nicks or pains or anything that you don't think is right, you can always call me to let me know what's going on,'" Cooper said. "It was probably the best, recovery-wise. I think the wrist surgery that first year here, I thought this one would have been a lot bigger just because it dealt with a bigger area of the arm. But it was about three months, and I could have played in a game probably after 12 weeks."

About a month ago, Cooper flew from California to South Florida to continue training. He is about six to seven pounds heavier after lifting weights a bit more during the extended offseason. He said he tends to be stronger playing first base, since he isn't taxed as much by the amount of running in the outfield. He was one of the Marlins who took part in workouts that Miguel Rojas put together in Palm Beach Gardens.

"To get up here and work out with the guys, hit, face live [pitching with] a lot of our pitchers was big for us," said Cooper, who has no restrictions. "I hadn't played since probably by the end of July. Just to get out there and do baseball stuff again [was good]."

UTIL Jon Berti (concussion)

Berti didn't expect to miss the remainder of the season when an Austin Adams slider on July 22 gave him his first concussion since 2017 and a laceration on the back of his head that required three stitches. Though Berti was hitting in the cage and taking ground balls by the final weekend of the season, he wasn't officially cleared before the lockout.

"It was kind of weird, just with the lockout situation," Berti said on Monday. "It probably would have happened back in December, but we couldn't talk. I was still working with the doctor back home in Michigan, and then I was also still keeping tabs with our doctor down here, so it was all good. But obviously a little different situation with the communication, but we're all good now."

Like Cooper, Berti also took part in Rojas' workouts.
