On the first day of legal sports betting in Massachusetts, MGM Springfield’s sportsbook took in $57,000 worth of bets, about 11.2% of the money wagered across the state on sporting events that day.

Overall, MGM Springfield reported $22.85 million in gross gambling revenue for January, its busiest month since October, the Massachusetts Gaming Commission said Wednesday.

State law requires all three casinos operating in the state report gross sports wagering receipts from the preceding month on or before the 15th of each month. January’s report released Wednesday included only one day’s worth of sports betting statistics in the numbers — wagers made on Jan. 31.
