Khalil Lee has the best all-around tools in the Royals system. He has quickness and loft in his left-handed swing, giving him surprising raw power for someone who stands 5-foot-10, and solid speed that plays on the bases and in center field. He also possesses a strong, accurate arm that has registered 29 assists in 253 pro games.
Refining his plate discipline will be the key to realizing his potential. He knows it and the Royals know it, and that's one of the main reasons he's playing for the Surprise Saguaros in the Arizona Fall League.

A second-round pick out of a Virginia high school in 2016, Lee ranked second in the Class A South Atlantic League with 17 homers and third with 65 walks in his first full pro season. But he also placed first with 171 strikeouts, whiffing in 32 percent of his plate appearances.
The Royals' No. 2 prospect made encouraging progress this year, batting a combined .263/.382/.390 with six homers, 16 steals and 59 walks in 100 games between Class A Advanced and Double-A. He improved his strikeout rate to 25 percent, shaving it to 24 percent after he was promoted in late June. He said he focused on working counts and toning down his two-strike plan, which were essential when he faced more experienced pitchers as just one of four players age 20 or younger to get regular at-bats in the Texas League.
"In Double-A, you see a lot of the pitchers are basically big league-ready," Lee said. "They can throw all their pitches for strikes, they can put it where they want it, thrown any pitch in any count, so it was just good to see that and experience that.
"Just being able to jump on that first good pitch I see was the biggest thing for me. I had to really just focus on hitting that first good one and putting it in play. When I didn't get that first one, I just had to battle and just fight to put the ball in play."
Lee missed the final month of the season after his lower back started to bother him and the Royals shut him down as a precaution. Kansas City vice president and assistant GM for player personnel J.J. Picollo said Lee made impressive strides with his approach before he got hurt.
"He was doing a better job of getting a pitch to hit and doing something with it," Picollo said. "Khalil has a good cockiness about him. He knows he's talented to get away with stuff and he needs challenges, so the AFL should be good for him."
Lee is well equipped to make it as a position player, and he also has pitching as a possible fallback. Several teams were intrigued by the upside he showed as a left-handed pitcher in high school, when he showed a low-90s fastball and a promising slider. He said he loves playing every day but would relish the opportunity to take the mound in pro ball.
"There are some times during the season where I try to get our pitching coach to throw me out there, but they won't let me do it," Lee said. "I do miss pitching.
"Hopefully, I don't have to go pitch. If I have to go pitch, that means something went wrong with the bat. But I do miss it and it was a lot of fun. I think I can get out there and spin a couple if I need to, for sure."
