Rea has been thoroughly average to bad in his time in the majors for his career. In his first (and so far only) lengthy stay, he logged over 100 innings in 2016 (mostly with the Padres), and pitched to a 4.82 ERA, which is likely a true reflection of his performance, since his FIP was 4.63. Not the results one would like from a pitcher enjoying the cavernous confines of San Diego. He required Tommy John towards the end of 2016, missed all of 2017, and struggled mightily in the minors and with the Pads in 2018 (5.73 era, 1.673 whip, 1.7 HR/9, and 4.3 BB/9). He ended up in the Cubs system in 2019, where he showed enough improvement to give the north-side brass a favorable impression (3.95 era, though his 1.35 whip was uninspiring and his SO/9 numbers were trending the wrong direction). His 2020, was, shall we say, not ideal: 5.79 era, 9.6 hits per 9, and an unsightly 1.9 HR/9 (though, some perspective is helpful here, as his FIP was a slightly better 4.98, his walks were way down, and this was all in a ludicrously small sample of 14 innings after all). At any rate, this paved the way for his release and subsequent move to Japan. His wife gave birth last year, however, and he returned home to be with her during and after the birth, resulting in his decision to stay stateside and give up pitching in the land of the rising sun. The Crew scooped him up in mid-August of this year, and he's been dealing in (admittedly only 35 innings of) AAA ball: 2.27 era, 1.037 whip, and critically, his HR/9 is down to 0.5, and his SO/9 is up to 8.8, which would both be career bests for him at any level above A-ball. As one would expect, he's been getting a few more ground balls, which helps to account for some of his improved HR-allowed numbers. Despite how much I may try and talk myself into Rea being a meaningful contributor, and the fact that the Brewers selected him to replace Williams at least suggests that they'd consider petitioning the league to allow him to be on the postseason roster should he merit an inclusion with his performance this week, I'm whistling past the graveyard here. The only encouraging sample size we have for him is quite small, and he's pretty unlikely to be any kind of a difference maker. Expecting him to be anything other than a Gustave substitute at this point would feel like setting oneself up for even more disappointment.
