WASHINGTON – Miguel Sano bid farewell to Class A baseball with a flourish on Sunday. And he wasn't the only one.

Sano, the Twins' top slugging prospect, hit two home runs during Fort Myers' 8-6 loss to Bradenton, then was informed that he had been promoted to Class AA New Britain. He will head north along with Miracle teammates Eddie Rosario and Angel Morales — each of whom also homered Sunday.

Sano, a third baseman who was rated the Twins' top prospect by Baseball America, leaves the Miracle after batting .330 with a league-leading 16 home runs and 48 RBI in a little more than two months in Fort Myers. Even better, said Twins minor league director Brad Steil, his defense has become more consistent. "His range is improving. He made some pretty good plays the first couple of months, going across the third-base line and making some pretty impressive throws over to first," Steil said.

Rosario, a former outfielder being converted to second base, "is becoming more comfortable over there every day," Steil said. "He's making a lot of plays there." Rosario, who batted .329 with six home runs and 35 RBI, was benched for three games late last month for a violation of team rules, but Steil said that "is not something out of the ordinary."

Morales, a center fielder, was batting .297 with seven home runs and 36 RBI.

To replace the trio, the Miracle activated former Gophers standout Mike Kvasnicka, an outfielder who has been sidelined all season by a broken hamate bone in his wrist, and first baseman Bryan Haar.

In another move, New Britain shortstop James Beresford was promoted to Class AAA Rochester. Beresford, who played for Australia in the World Baseball Classic, was batting .323 with 19 RBI for the Rock Cats.

Hot corner: cold

Twins third basemen entered Sunday a combined 7-for-68 (.103) with one double and one RBI since Trevor Plouffe went on the disabled list May 22. "We're catching the ball … but we miss the bat. It helps you fill out your lineup with him in there. He's a force," manager Ron Gardenhire said. "Trev's a guy who's supposed to be here to drive the baseball."

Plouffe was originally suffering from concussion symptoms, then went on the disabled list again because of a calf injury. He left for Rochester on a rehab assignment Sunday, and is eligible to return Thursday.

But Gardenhire strongly hinted that he's considering another third baseman, too, saying: "Deibinson Romero is playing real well in Triple-A right now. He's high on the radar."

Romero missed all of spring training due to a bureaucratic snag with his visa in the Dominican Republic, but he started hitting immediately upon his arrival in the U.S. The 26-year-old hit .355 in eight games for New Britain, and was sent to Rochester, where he hit .295 with four home runs in his first 17 games.

Etc.

• Reliever Ryan Pressly left Sunday's first game because of triceps soreness, but after submitting him to a series of tests, the Twins believe his condition is not serious. "It was really weird. I never had anything like that happen to me before," Pressly said.

• After an aggressive conditioning workout Saturday went well, Wilkin Ramirez took batting and fielding practice Sunday, the first time he has done that since suffering a concussion May 25.

• New Britain righthander Alex Meyer has a sore shoulder and will be given some extra time to rest before starting again. Meyer, acquired in the offseason for Denard Span, will see a doctor this week, Steil said, just to be safe.
