Notes
	I see massive upside in Donovan. Although T-Mobile Park is tough on hitters, he isn't really one for power, thriving on his excellent contact (career 13.5% strikeout rate and .361OBP). He is hitting .452 this Spring with a .514 OBP, and could be an elite table setter for a very good Mariners lineup, so it could be runs galore for Donovan. Anthony Gambale - Roto Street Journal
