ST. PETERSBURG -- The Twins had two pieces of good news on the injury front on Tuesday, regarding outfielders Josh Willingham and Darin Mastroianni, and a less-than-encouraging update on Wilkin Ramirez.
Assistant general manager Rob Antony said that Ramirez, on the 15-day disabled list, still hasn't improved much since sustaining a concussion on May 26. Ramirez was sent out on a Minor League rehab assignment on June 20, played three games with Class A Advanced Fort Myers and returned to the Twin Cities for further testing.
"He is not doing great. He's still having headaches, so the symptoms are all still there," Antony said. "We're just going to basically take it easy with him, do very little with him until the symptoms start to subside."
Antony had better news on Willingham, who started light exercises back in Minnesota, less than a week after undergoing arthroscopic surgery on his left knee to fix a torn meniscus. The procedure will keep him sidelined for four to six weeks, but Antony said Willingham hasn't experienced any swelling, which is a good sign.
"Everything's going fine there," Antony said.
Down in Fort Myers, Fla., Mastroianni worked out with the Twins' Gulf Coast League affiliate for the second day in a row. Mastroianni is on the 60-day disabled list with a left ankle stress reaction.
