It’s time for the first injury update of 2015, so let’s check in with closer Glen Perkins.

The two-time All-Star missed the final two weeks of the season because of a strained right forearm and nerve irritation in his left arm. He underwent multiple magnetic resonance imaging exams to make sure nothing serious was wrong, then spent the past several weeks rehabilitating the arm.

Speaking during a stop on the Twins’ annual winter caravan, Perkins said he has no worries about his health. He has not thrown off a mound yet but is playing catch with teammate Kyle Gibson in Florida, working up to 120 feet.

“I’m good, no issues,” he said. “My arm has felt really good and, being in Florida the last three weeks, playing catch down there instead of playing catch up here has made a huge difference.”

Perkins, 31, was 4-3 with a 3.65 ERA and 34 saves last season — not including the save he earned for the American League at the All-Star Game at Target Field.

Other health updates

Righthander Lester Oliveros, a late-season call-up, flew to the Twin Cities from the Venezuelan winter league recently to have his shoulder looked at. What the Twins found was very minor, and they are confident he will be ready for spring training. He gave up four earned runs over 10 innings with Caribes with five walks and 10 strikeouts. Oliveros threw the only pitch by a Twin that was clocked at 97 miles per hour last season — AL champion Kansas City, in comparison, threw 2,287.

• Third baseman Trevor Plouffe has resumed all baseball activities after breaking his left arm during the final week of the regular season.

Monitoring Johan

The Twins have been in attendance when Johan Santana has thrown in the bullpen this offseason, and there’s a good chance they will have a scout in attendance Tuesday when their two-time Cy Young Award winner makes his winter ball debut for Magallanes of the Venezuelan winter league.

Santana, coming back from two shoulder injuries, declined an offer from the Twins last spring and instead was going to sign with Baltimore. Before he could join the Orioles, Santana blew out his left Achilles’ tendon in June.

Another pitcher the Twins have watched throw recently is former Texas righthander Alexi Ogando, who is trying to come back from a sprained ulnar collateral ligament that he opted to treat with rehabilitation. Twins General Manager Terry Ryan said Monday he is not afraid to bring in another pitcher if he finds one he likes.
