Six MLB pitchers who have taken a big step forward in 2019

MLB: Chicago White Sox at Minnesota Twins

Eduardo Rodriguez, Boston Red Sox

It’s easy to see where Eduardo Rodriguez has made improvements this season. His 185.1 innings pitched and 17 wins are both career-high marks. However, his 3.64 ERA and 3.2 fWAR aren’t totally different from 2018 (3.82 and 2.1, respectively). He’s also seen a slight decrease in strikeout rate and a slight increase in walk rate.

So where is the huge step forward? Well, being healthy and consistent enough to make 30-plus starts is a tremendous plus for a Red Sox rotation that lacked both of those things this season. Another area is in his batted-ball profile — Rodriguez maintained a low hard-hit rate allowed (28.8%) but also bumped up his soft-hit rate from 19.8% to a league-leading 23.8%.

This has been accompanied by nearly identical improvements of about 10 percentage points in both his ground-ball rate allowed and fly-ball rate allowed. He’s really turned things on since the All-Star break, too — prior to the midsummer respite, E-Rod owned a 4.65 ERA through 102.2 innings. Over his most recent 82.2, though, he’s twirled a 2.40 ERA.
