Yusei Kikuchi: A Successful Starter-to-Reliever Move

We look at Kikuchi's velocity bump and strikeout-rate improvement after moving to the bullpen.

Yusei Kikuchi has been experimenting with a starter-to-reliever move recently. Focused one-inning outings lifted his velocity by 1-2 mph.

Post-move, his K/9 sits above 11 — a sharp improvement from the 8s he posted as a starter.

Left-handed relievers are in strong demand in MLB, and a role change directly improves his market value.

The open question is whether he commits fully to the bullpen or lands as a swingman.
