Also, DraftKings will match your first deposit in bonus funds at a rate of 20% up to a maximum of $1,000. For example, if you deposit $100, DraftKings will provide $20 for the deposit match along with the $50 bet.

In addition to the above promotion, new customers in Massachusetts can also receive $200 in bonus bets if their first wager at DraftKings Sportsbook is for $5 or more. The bonus bets are available whether that opening bet wins or loses.

Opening Day preview: Baltimore Orioles at Boston Red Sox

People in Massachusetts can now legally bet on the Boston Red Sox in the state. To kick off the 2023 MLB season, the Sox are hosting the Orioles for an afternoon game, as well as any MLB odds.

The Orioles finished last season just shy of October baseball, but their 83-79 record was their first regular season north of .500 since 2016. The contributions of catcher Adley Rutschman, a midseason call-up, were one of the reasons for the improvement. He’s back for his first full season in the big leagues.

The Sox are coming off a tough season, ending 78-84 and last in the AL East, just one year after making it to the ALCS. The team stayed busy in the offseason, as it parted ways with Xander Bogaerts and brought in outfielder Masataka Yoshida from Japan, and veterans Justin Turner and Adam Duvall. Boston has shown a lot of variance in performance over the last 10 years, including two World Series rings and a few last-place finishes.

All of the sportsbooks above have the Sox as home favorites in this matchup. Last year, Boston boasted a 32-18 record as the home favorite, while the Orioles were 34-43 as road underdogs.
