There is no such thing as a can’t miss prospect, that’s the whole reason the Brewers have placed so much emphasis on building and maintaining organizational depth since Stearns/Arnold arrived.
But ultimately, yes, it’s too early to tell because the samples are still so small. Even with that said, all three have mostly lived up to their scouting reports in their brief taste of MLB thus far.
Mitchell has flashed the excitement with a 119 wRC+ in his 141 PAs, but questions linger about how sustainable that is with a 38.3 K% and .441 BABIP under the hood plus all the injuries. Hopefully we’ll have another two tree hundred PAs to go off by the time the season’s over, but I’m definitely not counting on it.
Frelick has 315 PAs now with better than average plate discipline (128 BB%+ | 83 K%+) and an affinity for singles (104 AVG+) but a paucity of pop (49 ISO+). The high likelihood of Sal being an average player was what carried his profile and so far that’s what he’s delivered.
Wiemer always was considered the most boom or bust of the three and so far it’s been mostly bust. But even with as bad as the bat has been, he’s still notched 1.0 WAR in his 421 PAs on account of defense and base running so his overall impact is in the red.
All told the three of them have totaled 3.1 WAR over their first 877 PA and counting which is pretty cromulent production for guys just getting acclimated to MLB.
Meanwhile, our best non-Yelich OF the last two years has been the guy a vocal segment of the internet was up in arms about even being put on the 40 Man two winters ago just because they’d never heard of him.
