– The Twins should know by the end of the day Wednesday if they will have shortstop Jorge Polanco available for Opening Day. Polanco came down with upper arm fatigue late last week.

Polanco on Tuesday went through fielding drills with no setbacks, then he went to the back fields and was the designated hitter in a minor league intrasquad game.

“Jorge had a good day,” Twins manager Rocco Baldelli said. “We took him out, worked him out at shortstop, made some throws, moved him around from different angles, then he went over and played on the minor league side, DH’ed in that game, swung the bat well. He went very well the entire day. It was a good day for him. I think we feel good about how he is doing physically.

“I think we are pretty comfortable about where we sit. I think the final decision will be made relatively soon on him, but I think it’s tracking in a positive direction with him.”

As a precaution, infielder Ronald Torreyes, who was 0-for-1 in a 5-5 tie with Colorado on Tuesday, flew with the team to the Twin Cities. He’ll be added to the roster if Polanco can’t play, which seems less likely. The Twins made sure that Torreyes understood the possibility that he could be headed back to Florida if Polanco is healthy enough to play.

“Ronnie had a great camp,” Baldelli said. “He’s not only a favorite on the coaches’ side of the clubhouse, he’s a favorite in that room over there with all the players because he brings it. As a person, he brings it every day. He’s a lovable guy. Plays his tail off every day.”

The Twins don’t have to finalize their roster until Thursday, but indications are that they will make all their necessary roster moves to get to 25 players. That includes placing third baseman Miguel Sano (lacerated heel), lefthander Gabriel Moya (sore shoulder), righthander Matt Magill (biceps tendonitis) and righthander Addison Reed (left thumb) on the injured list.

Ready for righthies

One thing Baldelli didn’t get much of a chance to work on during spring training is putting together a lineup against lefthanded starters. The Twins just didn’t run into many lefties when it was time to get the regulars on the field.

And indications are that the Twins won’t run into many lefthanded starters during the first month of the regular season, either.

He did, however, get to see his lineup against righthanders in action. And he indicated that the lineup he used in recent exhibition games will be the one he’ll use on Thursday.

That one goes in the following order: Right fielder Max Kepler, shortstop Polanco (if healthy), designated hitter Nelson Cruz, left fielder Eddie Rosario, first baseman C.J. Cron, third baseman Marwin Gonzalez, second baseman Jonathan Schoop, catcher Jason Castro and center fielder Byron Buxton.

Etc.

• Thursday’s opener is not quite sold ou. The club hopes to announce a sellout by the end of the day Wednesday.

• Infielder Adam Rosales, released by the Twins last week to look for work elsewhere, has returned to the Twins and signed a minor league deal. He will report to Class AAA Rochester.
