The Mets made what they perceived as a last-ditch effort to sign Pete Alonso and when that was rejected began their pivot away from their slugging first baseman, The Post has learned.

On Thursday, Joel Sherman of The New York Post revealed that the Mets offered Alonso a three-year contract in the $68 million-$70 million range. After the four-time All-Star rejected it, they set their sights on adding a top-tier reliever and potentially executing a trade for Toronto Blue Jays slugger Vladimir Guerrero Jr.
