Hitting
Guilliams is an excellent mistake hitter who belts middle-of-the-plate fastballs or hanging breaking balls. Guilliams always has been a line-drive hitter who uses the entire field. He hits righthanders and lefthanders with equal consistency. He likes to pull the ball, but don't be surprised if he puts the ball the opposite field from time to time. He's a smart batter and takes good note of how the fielders are shading him.
Baserunning & Defense
Aggressive on the basepaths, Guilliams is a good basestealer and takes the extra base when needed most. He doesn't get good jumps on grounders, but his routes are fine and his hands aren't bad. Guilliams has one of the strongest arms among first basemen.
2025 Outlook
Guilliams is ready for the big time. The Retired or Inactive Players will call him up as soon as they can figure out who to send down. Guilliams is in charge when he's at the plate.
