According to Baseball America, anyway, in it’s recent draft assessment.
Lewis "earned 70 grades (on the 20-80 scouting scale) for his raw power," the magazine reported, "and was showing that power in pro ball before a knee injury ended his season July 19."
The Mariners selected Lewis in June with the 11th overall pick. A junior at Mercer University, he was the consensus college player of the year.
Lewis, 21, then batted .299 (35-for-117) prior to the injury in 30 games at Short-A Everett with 26 runs, eight doubles, five triples, three home runs and 26 RBIs. He also had a .915 OPS (on-base plus slugging percentage).
"He was giving us every reason to believe," general manager Jerry Dipoto said, "he was exactly the player we thought we were drafting."
Lewis suffered the injury in a collision at the plate and underwent surgery to repair a torn anterior cruciate ligament in his right knee along with torn cartilage. He isn’t expected to return to active duty until late in the 2017 season.
While Baseball America cited Lewis as the draft’s top power-hitting prospect, it tabbed third baseman Joe Rizzo, a second-round pick, as the Mariners’ best "pure hitter" among the organization’s selections.
Rizzo, 18, batted .291 with two homers and 21 RBIs in 39 games at Peoria in the Arizona Rookie League. He drew raves for his "short, strong left-handed swing."
Among the other citations from the Mariners’ 29 selections:

Right-hander Kevin Gadea pitched five more scoreless innings Friday for Aragua in the Venezuelan Winter League but settled for a no-decision when the Tigers’ bullpen blew a lead in a 5-3 loss to Margarita.
Gadea, 21, also threw five scoreless innings in his only other start. He has allowed five hits in his 10 innings while striking out five and walking three.
The Mariners Gadea, a Nicaraguan native, as a 16-year-old in 2012. He was a combined 4-1 with a 2.36 ERA in 15 games, including eight starts, for Peoria and Lo-A Clinton.
