Jeremy Jeffress has appeared in 13 of the Milwaukee Brewers first 23 games. He’s worked 12 2/3 innings, and he owns a 0.71 ERA. Jeffress has only walked two, while striking out 11. He’s actually allowed more walks than runs. Is Jeffress really this good?
What do the peripheral numbers say?
Well, they don’t say that he can continue to post a sub-1.00 ERA. They do say that he’s been solid. Not ‘sub-1.00 ERA’ solid, but a capable member of the Milwaukee Brewers relief corps.
His 2.61 xFIP indicates that his actual 0.71 ERA is a mirage, but he’s still pitching like a sub-3.
