On the first day of June, the Nashville Sounds utilized their biggest feature from the month of May and their top prospect led the way.
Oakland's No. 1 prospect Franklin Barreto continued his team's power surge at the plate by hammering a go-ahead grand slam in the ninth inning as Triple-A Nashville rallied to take down Iowa, 5-2, at Principal Park.
Hitless entering his final trip to the plate Thursday night, Barreto came up with the bases loaded and two away in the ninth. The shortstop smashed a 1-0 pitch from Iowa reliever Felix Pena and deposited it beyond the wall in left-center field to turn a 2-1 deficit into a 5-2 lead.

"The secret to his success is just controlling the strike zone really," Sounds manager Ryan Christenson said of Barreto last month. "It's that simple for him. When he's dialed in and not chasing balls out of the zone, he's good. He's a guy that can flat-out hit. When he's getting pitches in the zone that he can do something with, he always hits them hard."
Gameday box score
Barreto's blast continued a trend for the Sounds at the plate. In April, Nashville scored 84 times and hit 18 homers over 21 games. In May, those totals ballooned to 153 runs and 46 homers in 30 games.
MiLB includeBarreto cooled last month after a hot start, batting .265/.295/.419 in 27 games after a .349/.404/.566 line in 21 April contests, but Thursday's blast snapped an 0-for-10 skid for baseball's No. 45 overall prospect.
Oakland's No. 21 prospect Jaycob Brugman went 2-for-4 from Nashville's leadoff spot.
Victor Caratini, the Cubs' No. 12 prospect, went 2-for-4 with a double for Iowa.
