Terms of the deal weren't divulged, but multiple reports peg the deal to be worth $68 million. The flamethrowing righty was particularly impressive with the Red Sox, for whom he pitched to a 3.33 ERA in 54 innings to close out the season before dazzling with a 1.61 ERA in 22 1/3 postseason frames.
A 28-year-old right-hander who has had a pair of Tommy John surgeries, Eovaldi was acquired by Boston from Tampa Bay on July 25.
"We're very happy to have Nathan back with us", Red Sox president of baseball operations Dave Dombrowski said in a news release. Following the trade, he went 2-0 against the Yankees with a 0.39 ERA in four starts against NY including his win in Game 3 of the ALDS.
As for the specific Yankees free agency plans, MLB Network insider Jon Heyman has the scoop on who the team is going after next. He had his best season in 2018, however, returning in late May after missing all of 2017 after surgery in August of 2016, then dramatically increased his stock with a huge performance in the postseason.
It comes as no surprise that Eovaldi is using his strong 2018 campaign to attempt to command a four-year deal.
If he spends the next four years pitching like he did in the playoffs, the contract will be a bargain. Eovaldi, 29, obviously has the big fastball, but also began utilizing a cutter more often, throwing it 32 percent of the time after first unveiling it with the Yankees in 2016.
