Mets acquiring Ryan Helsley from Cardinals as bullpen makeover continues

The Mets keep on bolstering their bullpen.

The Amazin’s are acquiring right-handed reliever Ryan Helsley from the Cardinals in a trade, The Post’s Jon Heyman reported.

Three prospects are going back to St. Louis: infielder Jesus Baez and pitchers Nate Dohm and Frank Elissalt.

The move comes hours after the Mets picked up submariner Tyler Rogers from the Giants.

It’s the third major bullpen pickup in the last week after they traded for lefty Gregory Soto from the Orioles on Friday.

Helsley, a two-time All-Star, has a 3.00 ERA and 21 saves this season after leading MLB in saves with 49 last year.
