IMO the Brewers probably tried to do something with Brown, but got no takers. He was badly overmatched at AAA last year (5.79 ERA - many more hits than IPs - 1.73 WHIP - almost 5 BBs per 9). I don't see any team thinking he would be Rule 5 material. I believe the Brewers left him unprotected because they feel he isn't going anywhere so why waste a spot for him. He obviously didn’t have a stellar campaign, but when put into the context of the overall PCL run environment last season he really wasn’t nearly as bad as we would traditionally think of those numbers. There were 98 pitchers in the PCL that made 10+ starts last year (Zach Brown made 23 starts which was 8th most in the PCL last year), and the average age of those starters was just over 26 years old (average age of all PCL pitchers was 26.7). Brown was 24 years old last season, so still a couple of years below the average age. Below is Zack Brown’s stat line compared to the league average pitching results in the PCL for 2019. League Average (PCL): 5.49 ERA 1.523 WHIP 9.8 H9 1.5 HR9 3.9 BB9 8.9 SO9 Zack Brown: 5.79 ERA 1.731 WHIP 10.6 H9 1.2 HR9 4.9 BB9 7.6 SO9 So again, he was not good last year, but considering his previous track record as well as the fact he was in a horrendous run environment last year, I will be a little surprised if nobody takes a chance on him in the Rule 5 draft.
