CHARLESTON, W.Va. (AP) — The director of the West Virginia Lottery has resigned, just after the launch of sports gaming at the Hollywood Casino in Charles Town.

Gov. Jim Justice said in a news release that Alan Larrick informed him he would step down as director effective Saturday.

Justice said Larrick "has done an excellent job and he will be missed."

Justice said Friday he has appointed West Virginia Deputy Revenue Secretary Doug Buffington as acting director.

Larrick was appointed to the post in January 2017. He oversaw a 12 percent increase in instant sales, the first year-over-year increase in instant sales in more than a decade and a total sales increase from the previous year of $12 million, the first year-over-year sales increase since 2012.

Hollywood Casino at Charles Town Races became the first sports book to begin operations in West Virginia on Thursday.
