With a revamped roster, the Mets are +850 to win the World Series, per DraftKings Sportsbook, only behind the Los Angeles Dodgers (+285), the Philadelphia Phillies (+800) and the Detroit Tigers (+800). With the trade deadline moves, New York now has a payroll of $339.8 million, per Spotrac.

The New York Mets are one of the more intriguing teams at the trade deadline. They could land a deal for Chicago White Sox outfielder Luis Robert Jr.

On the eve of the deadline, the Mets and Giants completed a trade that will send standout submariner Tyler Rogers to Queens. In a package that contains plenty of prospect name value, big league reliever José Buttó plus Drew Gilbert and Blade Tidwell will head to San Francisco.

The Mets are acquiring hard-throwing closer Ryan Helsley from the St. Louis Cardinals on Wednesday, a day before the July 31 Major League Baseball deadline, the team announced Wednesday. The Cardinals get back three minor leaguers: shortstop Jesus Baez and right-handed pitchers Nate Dohm and Frank Elissalt.

The Mets traded three players to the Cardinals for closer Ryan Helsley, who was expected to serve as the setup man in New York for Edwin Diaz.
