He said adding a new casino in Prince George's County would cause more Maryland residents to spend gambling dollars at home.
"Moreover, the addition of table games would allow Maryland's facilities a chance to finally compete with Charles Town on a level playing field," Basu said.
He said Maryland's lack of table games has severely limited its ability to fully compete with Charles Town.
Charles Town has faced increased competition from Maryland this year. The Maryland Live! Casino, which has more than 3,000 slot machines but no table games, opened in Anne Arundel County in June.
But Basu said Charles Town's revenues have declined by only 6 percent since that casino opened. The decline was due to losses in slot machine revenues; Charles Town's table game revenue hasn't changed since Maryland Live opened.
"The implication is that it is possible to compete with Charles Town, but Maryland's lack of table games has severely limited its ability to fully compete to date," Basu said.
West Virginia Lottery spokesman Randy Burnside on Wednesday declined to comment on the Sage report.
"I cannot speak to numbers that were gathered by an outside source and not collected by our lottery," Burnside said.
West Virginia Lottery officials have said they are closely monitoring the situation in Maryland and preparing for potential impacts on this state's gambling industry.
While out-of-state competition has hurt the state's Northern Panhandle casinos, officials have said the Baltimore-Washington D.C. metro area is a much larger market and could possibly support more casinos.
However, Lottery officials are being cautious. Revenue officials have lowered forecasts for table game revenue in coming years to account for out-of-state competition.
