Height: 6’5″Weight: 205 lbs.Bats: RightThrows: Right
Summary:
The offensive identity leans heavily on strength, leverage, and bat speed, with Keen already showing the ability to drive the ball with authority in game settings. When he stays on time, the swing works shorter than the frame suggests, allowing the barrel to get out front and punish mistakes to the pull side. The approach is aggressive and will come with swing-and-miss as he faces better sequencing, but the raw power is unquestioned and shows up consistently in contact quality. As his body continues to mature, the profile points toward impact power that fits comfortably in the middle of a lineup.

Defensively, the arm strength stands out and supports a long-term fit at third base, where his athleticism is enough to handle the position even if the range isn’t elite. He brings legitimate two-way intrigue as well — showing arm speed on the mound with a fastball into the low 90s and usable secondaries — but the bat clearly drives the projection. The pitching adds value to the overall profile, yet the developmental ceiling is tied to what he becomes offensively, where the tools and physical projection give him real upside if the hit tool continues to progress.
