This pen is a poor return from Knebel away from being an unmitigated disaster. You have 3 known commodities and 1 is coming back from TJ within the year. Either you like these JAGs (just a guy) way too much or you don't value the pen at all. 2 of them in the pen to start the year, maybe. 1 sure. 5? Just cancel the season. To put it bluntly, I really like Perdomo and Andrews. Both lefties, both rack up high K/9 totals. Andrews has shown he can go multiple innings, and he has a decent bat. Devin Williams also looked good in Milwaukee, IMO. Feyerisen and Yardley are interchangable with the likes of Rasmussen, Supak, Roegner, File, Bettinger, Burnes, QTC, Black, Wahl, Faria. Heck, add Zach Brown if he bounces back any. Andrews will likely begin at AA this year, and if he pitches well, MIGHT see AAA by the end of 2020. The chance that he makes any sort of significant major league impact in 2020 is about as close to zero as you can get. Perdomo has a chance, though.
