Byron Buxton, CF: Wrist injuries and a concussion limited baseball's consensus top prospect to 31 games last year. In his last full season, 2013, he batted .334 with 18 triples, 12 homers and 55 stolen bases.

Miguel Sano, 3B: He missed all of 2014 recovering from Tommy John elbow ligament replacement surgery. Considered the top power prospect in the minors, he had 35 homers and 103 RBI in 2013.

Alex Meyer, RHP: He's 6-foot-9 with a mid-90s fastball but lacks the offspeed pitch needed in the majors. He was 7-7 with a 3.52 ERA at Class AAA last year and has averaged 10.4 strikeouts per nine innings in his minor league career.

Jose Berrios, RHP: The 20-year-old could debut in the majors this summer; he was 12-8 with a 2.77 ERA at three minor league stops last season and has averaged 9.5 strikeouts per nine innings in three seasons in the minors.

Kohl Stewart, RHP: The Twins will take it slow with their 2013 first-round pick (fourth overall) because shoulder problems have ended his first two professional seasons early. He was 3-5 with a 2.59 ERA at Class A last season.

Eddie Rosario, OF-2B: His trek to the majors was slowed by a 50-game suspension served last season for testing positive on a drug test. The 23-year-old is a career .294 hitter over five minor league seasons.

Jorge Polanco, SS: Made his major league debut last summer at the age of 20, and had a pair of hits — a double and a triple — in six at-bats. A career .287 hitter with gap power — 85 doubles, 21 triples — in five minor league seasons.

Nick Gordon, SS: The 19-year-old fifth overall pick in last year's draft jumped from high school to Rookie League Elizabethton and held his own, batting .294 and stealing 11 bases in 57 games.
