NO GUARANTEES

Here are a few reasons why Miguel Sano and Byron Buxton could — or could not — be headed toward stardom in the majors.

Shooting for Stardom

• Sano's 2015 results — .268, 18 homers and 52 RBI in 80 games — caused the league to take notice.

• Sano was considered the top slugging prospect in the minor leagues. Totaled 105 homers in five seasons.

• Buxton was the consensus No. 1 prospect in baseball for each of the past two seasons. Could so many be wrong?

• Buxton is a tremendous athlete, a superb center fielder with speed and power who, at the two highest minor league levels last year, batted .305 with 13 triples and seven homers in 72 games.

Falling from grace

• Remember Kennys Vargas? Many players have had similarly strong first seasons like Sano's, only to falter in Year 2.

• Sano's strikeouts are a concern — 119 in 279 at-bats last season. Plus, he is moving to a new position.

• Buxton has yet to show he can hit major league pitching; .209 with the Twins last season with 44 strikeouts in 129 at-bats.

• Buxton also has been injury-prone throughout his career, suffering shoulder, wrist and thumb injuries and a concussion.
