Hosmer, according to local reports, arrived with several teammates after they finished off a sweep with their 8-3 win over the Angels and picked up the tab for everyone in attendance at the Irish bar in Kansas City's Power & Light District for the last hour of the night.
Hosmer spent $3,000 on the early Monday morning bar tab, and his teammates shared a $12,000 bill, the Kansas City Star reported, citing a Royals official.
The Royals return to the field for Game 1 of the ALCS on Friday at Baltimore.
Some of the revelers were drawn at least in part by a Hosmer invitation via Twitter:
