The Boston Red Sox have locked up somebody they hope to be a franchise cornerstone.

Kristian Campbell, one of their top prospects who made the big league club out of spring training, has signed an extension that could keep him with the club for the next 10 seasons.

The two sides agreed to an eight-year extension worth $60 million, ESPN reported. The team said the deal comes with club options for both the 2033 and 2034 seasons.

Since Campbell was called up for opening day, he was under team control through 2030 — he'd make the league minimum for his first three seasons before arbitration kicks in.

Instead, the Sox and Campbell have decided to forgo all of that and be locked down for at least the next eight years.

Campbell has made an awesome first impression in the early going. The 22-year-old infielder is 6-for-16 (.375) with a home run. He played at all three levels of minor league ball last season and raked everywhere he went. He hasn't even yet played a home game at Fenway Park, but that will come on Friday.
