The Mariners have plenty of top prospects to keep your eyes on this spring. When it comes to pitching, Kade Anderson is the player most likely to get called up this year and had a strong showing in his spring training debut. Although he's further away from the big leagues, Ryan Sloan has also impressed in his only outing so far but he still has plenty to learn.
