It's interesting that MANY of you did not want the Sox to sign Eovaldi. I think it was brilliant move from the perspective of hedging against both Sale and Porcello leaving the Sox after 2019 season.
Not only that, in a jam, Eovaldi can indeed step in and close for us. If we don't sign a closer, Sox will name either Barnes or Brasier as the closer. And If they 1) falter before the trade deadline or 2) a starter emerges from the farm at some point this season or 3) Sox is unable to trade for a closer at trade deadline, you may see Eovaldi move over to the pen to save his arm. We know that Eovaldi is all about winning, he's signed for four years, He's not playing for a new contract in 2019. I can't see him saying no.
In essence, if Eovaldi does indeed end up closing, we gave Kimbrel's 4 year deal to Eovaldi. Unlike Kimbrel, our new closer Eovaldi, can start or come in in relief and pitch 7 innings.
