The deal is the third largest in MLB history and the second richest in present-day value behind only Juan Soto's contract.

Guerrero's contract, which includes no deferrals, also sets the record for the largest contract extension in MLB history. The record previously belonged to Mike Trout, who prior to the 2019 season signed a $426.5 million extension with the Los Angeles Angels .

Alonso is off to a blistering start for the Mets this season. He has three home runs and 11 RBIs through nine games this season and has multiple game-winning hits. Juan Soto is ascending after shaking off the cobwebs and Jesse Winker has come in clutch multiple times.
