2018 Level: AAA/MLB
Current/Future/Ceiling Grades: 45/45/45
What we know:
Stewart is an MLB ready guy, who offers above average power and patience at the plate. He’s limited to an outfield corner and is only an average defender there, so the value will be tied to the bat. Stewart lacks the bat to ball skills to handle elite stuff, but will work pitchers and crush mistakes. Stewart struggled in AAA in 2018 and it looked like he was trying to do too much at the plate. He showed better in his MLB debut, where he prolonged ABs and was able to foul off pitches at a high rate until he got a pitch to hit.
What we don’t know:
How far will his strike zone recognition and smart approach take him? Stewart has a profile without much room for error and with his stocky running back frame, he’s likely to lose speed and defensive ability earlier than most. So getting the most out of his bat is very important.
What we think:
We think once pitchers get the book on him, he’ll have trouble producing enough to be an everyday player. He should be able to provide value as a platoon bat who plays both outfield corners, works hard, takes professional ABs, and adds solid baserunning skills (even though the speed is just average). He may have a season or two at his peak when he can handle an everyday role on a rebuilding team, but expect the athleticism to diminish towards the end of his team controlled years.
