Maryland’s newest casino held on to the state’s gaming revenue crown in April, in which overall revenue was the second highest on record.

Figures released Friday by the Maryland Lottery and Gaming Agency show the state’s six casino operators generated total gaming revenue of $135.7m in April, second only to the $141.2m earned in March.

April’s total represented a 30.6% improvement over the sum earned in the same month last year. However, subtracting the contribution from MGM Resorts’ National Harbor, which opened last December, the apples-to-apples numbers of the five other casinos fell 17.4%.

National Harbor was once again the state’s top earner, taking in over $49.9m in April, but this was down from its record $51.2m performance in March. Runner-up Maryland Live suffered a similarly small decline, dropping to $45.3m from $46.6m in March, although April’s total was down more than one-fifth from the pre-National Harbor market in April 2016.
