最終周回で彼はまくりを決めて優勝した。
On the final lap, he executed an outside overtake and won.
Keirin is the sport itself; まくり is a specific overtaking maneuver within keirin.
Derived from the verb 捲る (まくる, 'to roll up' or 'to turn up'), referring to something rolled or turned up, hence an unframed scroll painting. The keirin sense likely comes from the image of 'rolling up' from behind.
