PHILADELPHIA — It didn’t take long for an Opening Day win to become old news Monday.

The Boston Red Sox announced shortly after defeating the Philadelphia Phillies 8-0 at Citizens Bank Park that they have signed pitcher Rick Porcello to a four-year contract extension through the 2019 season.

The Boston Globe’s Alex Speier reported Porcello’s deal is worth $82.5 million.

The move comes as a bit of a surprise, as Porcello indicated Sunday that he and the Red Sox agreed to table contract talks until the offseason so the right-hander could focus on pitching.

Porcello, whom the Red Sox acquired from the Detroit Tigers over the offseason in exchange for outfielder Yoenis Cespedes, was entering the final year of his contract. The 26-year-old is coming off his best season to date, though he has yet to pitch a single regular-season inning for the Red Sox.

Porcello is scheduled to make his Red Sox debut Wednesday. He’ll now do so with some more peace of mind, as he’s about to become a very rich man.
