Pitching is probably going to be the one area that will kill the Red Sox chances in 2020, at least as the roster is currently constituted. After losing Rick Porcello in free agency and trading David Price, the Sox current rotation is Chris Sale, Nathan Eovaldi, Eduardo Rodriguez, and Martin Perez.
The first two have spent significant time on the injured list the last two seasons while Rodriguez pitched the best season of his career (and the most innings) in 2019.
As for Perez, he was at best thought of as the number five starter when Bloom acquired him in the offseason. There’s also not a lot of pitching depth in the minors, with prospects Jay Groome, Tanner Houck, and Bryan Mata still a ways off from seeing big league action.
There are some notable names left on the free-agent market, although none of them are particularly attractive. Andrew Cashner, who was unimpressive in Boston after being acquired last year, would at least be a known quantity, but I’m not sure the team or fans want to experience that again.
Older available pitchers like Jason Vargas and Jeremy Hellickson don’t move the needle at all and should be last-ditch signings if it gets that dire. Of course, old friend Clay Buchholz is also available…let’s move on.
