Sano, 22, has been one of the best prospects in all of baseball over his entire minor league career, with his apex coming before last season, as Baseball America had him No. 6 on their top 100 rankings. He was ranked No. 13 pre-2015.
Tommy John surgery forced Sano to miss the entire 2014 season. Many were nervous that Sano could have been hurt developmentally, however, he practically picked up exactly where he left off in Double-A.
The Dominican Sano has been hitting .274/.374/.544/.918 in 286 plate appearances this season. He has immense power, hitting 15 home runs, 18 doubles, a triple, and driving in 48 runs. Sano's best defensive asset was his arm, but it has not come all the way back to full strength post-surgery.
On the Twins' 25-man roster, Sano will be replacing designated hitter Kennys Vargas, who was optioned to Double-A earlier Wednesday. He had already been on the 40-man roster.
This season has been deemed "the year of the prospect," as some of the best minor leaguers have all been brought up at some point this year, including Kris Bryant, Carlos Correa, Sano's new teammate Bryon Buxton, Maikel Franco, Noah Syndergaard, Steven Matz, Francisco Lindor, Kyle Schwarber, and others.
