Florida State League opponents were batting .398 against the 22-year-old right-hander, who started the year with Class A Beloit, through his first six starts at the new level. That led to an 0-6 record and 11.22 ERA. But the pitcher who had been very hittable in the Sunshine State was nearly unhittable Sunday.

The Twins' No. 16 prospect combined with relievers Nelvin Fuentes and Matthew Hauser to one-hit Daytona in a 4-0 win at Hammond Stadium.

Boer allowed a single to Greg Rohan with nobody out in the second inning before keeping the Cubs hitless the rest of the way. He worked into trouble in the third when a walk, his own throwing error and a hit batsman loaded the bases, but Richard Jones' groundout ended the frame without any further damage.

The former University of Oregon hurler retired six in a row in the next two frames to finish his outing. He finished the day with one hit and two walks allowed and five strikeouts through five innings.

Fuentes allowed three walks and struck out one in 2 2/3 innings of relief and Hauser pitched 1 1/3 perfect innings for his first save of the season.

Boer, the Twins' second-round pick in the 2011 First-Year Player Draft, earned his first win at Class A Advanced in his seventh start at the level. His ERA improved by nearly two runs to 11.22 with the shutout -- another first at Fort Myers -- although the mark still remains far from the 3.58 stat he put up in five starts at Beloit earlier this year.

Twins' No. 4 prospect Oswaldo Arcia provided all the offense the Miracle would need, with a home run, two RBIs and two walks. The outfielder, who started at designated hitter Sunday, ranks fourth in the Florida State League with a .330 average.
