Boyd pitched to a 4.59 ERA last season. He started off hot – he owned a 2.85 ERA in his first 12 starts against his 5.67 ERA in his last 20. But his K/9 of 11.99 in those starts was the ninth-best mark in all of baseball.
Keep in mind Boyd also pitched against the division winning Minnesota Twins and 93-win Cleveland Indians six times. In those starts last year, he allowed 26 earned runs in 37.0 innings (6.32 ERA). That means against all other opponents, he owned a 4.27 ERA.
Boyd is similar to Matz where his performance could be better, but where he differs is that he is one of the best strikeout pitchers in all of baseball.
The most important aspect of this, however, is that Boyd still has three years of control left. If the Yankees were able to pull this off, they’d have four starters under control through at least the 2022 season. Cole, Severino, Montgomery, and Boyd is a nice front four, while Deivi Garcia is up and coming.
