Having followed them for a few years now, it always seems to me like the MLB Pipeline lists tend to put more weight on the draft positions. Early round picks will always show up high on the team lists (and some in the overall lists) and always (or nearly always) in the same order they were taken. More inertia in the system. Which is neither good or bad, just is. But also tends to lead to them differing somewhat from BA/Fangraphs/BP for example. And Keith Law will do his own thing.

Not prospect rankings per se, but the PECOTA spreadsheet was published today. That is the raw data without playing time or park adjustments or anything. It's basically projecting a ton of players from each organization, and former players who haven't appeared for other teams; so Brewers list includes Matt Albers and Brett Anderson, Cubs has Addison Russell and so forth. From a "prospect" point of view it's interesting because while Yelich and Cain as #1 and #2 in terms of WARP on the team is hardly surprising, #3 and #4 are... Luis Castro and Cooper Hummel. Which is quite surprising tbh, even if Hummel hit very well in AA in 2019 and Castro absolutely crushed it in A+ (1.001 OPS in 475 PAs). Yet Hummel was unprotected (and wasn't taken) in the Rule 5 draft, and Castro was let go by the Rockies after that monster season. So you'dthink that the teams don't really expect their performance to carry up the levels. But PECOTA does. For comparison, Castro isn't projected by ZiPS, while ZiPS projects Hummel for 76 wRc+.

Now purely looking at minor league stats without context is a bad way to scout, but projections like this can still be of some interest to use alongside scouting. Projections will after all look at which minor league statistical attributes tend to best correlate with major league success and such. What they'll miss are players who hit well because they're older, stronger or simply feasting on poor control and underdeveloped changeups.

I have absolutely no idea how the Brewers view either of these two players, just thought it was curious enough to share.
