With Edwin Encarnacion no longer in the fold after his departure via free agency, left-handed slugger Rowdy Tellez, fresh off of his career-best campaign in Double-A last season, seems poised to step in at first base, though probably not until later in the year.
Meanwhile, Toronto's success in developing young starting pitchers such as Aaron Sanchez and Marcus Stroman bodes well for the futures of right-handers Sean Reid-Foley, Conner Greene, Jon Harris and T.J. Zeuch, all of whom made strides last season and are on pace to debut before the end of 2018.
Looking beyond next season, new No. 1 prospect Vladimir Guerrero Jr., whom the Blue Jays signed for $3.2 million in July 2015, is the gem of the system and has one of the highest ceilings among all prospects. Though at age 17, he's likely several years away from making an impact. Toronto added another promising young hitter with baseball bloodlines in the 2016 Draft in Bo Bichette, who, after signing as a second-rounder, batted a robust .427/.451/.732 with 15 extra-base hits and 36 RBIs over 22 games in the Gulf Coast League.
Here are the players whose ranks changed the most from the 2016 preseason list to the 2017 preseason list.
Jump: Patrick Murphy, RHP (2016: NR | 2017: 17)
Fall: Reggie Pruitt, OF (2016: 13 | 2017: 27)
Players are graded on a 20-80 scouting scale for future tools -- 20-30 is well below average, 40 is below average, 50 is average, 60 is above average and 70-80 is well above average.
