It's hardly as exciting as any trade deadline moves, but the roster aftermath of so many players swapping teams at one time leads to a whole collection of talent hitting waivers and free agency. You'll rarely find a gem just waiting to be picked up at this point in the season, but every now and then, you can uncover a diamond in the rough.
That's exactly what the St. Louis Cardinals will attempt to do with former top-100 prospect Everson Pereira, whom they claimed off waivers from the Chicago White Sox. He slides right into one of the vacated 40-man roster spots that were created in the Dustin May/JoJo Romero trade, though he's out of minor-league options, so he'll have to stick around in the majors if the Redbirds don't want to subject him to waivers again.

Everson Pereira must prove health, strikeout concerns are behind him to earn serious role with Cardinals
The Cardinals opened up a spot in their outfield mix by trading away Lars Nootbaar to the Arizona Diamondbacks at the deadline, so it's not hard to see where and how Pereira will factor in down the stretch. He's been respectable when healthy this season, hitting .225/.284/.438 (98 wRC+) and accruing 0.2 fWAR in 27 games played.
"When healthy" is the key phrase there, though, since that's been a rarity in 2026 for the 25-year-old. He has hit the injured list three times this season with various maladies and missed multiple other contests due to nagging bumps and bruises. A capable fourth outfielder though he may be, availability is still the best ability, and Pereira hasn't done much to prove that he's got that in the toolbox right now.
If you can look past that, there is a quality bench player worthy of playing time in his profile. Someone who produces league-average offense while playing league-average defense and runs at a league-average speed doesn't sound particularly valuable, but being able to do everything at a competent level does give Pereira a higher floor than other top prospects who haven't lived up to expectations.
The biggest concern (besides health) is that the strikeout habits that tortured him in the minors have followed him to the majors; he had a 34.1% strikeout rate with the White Sox this year and is sitting on a 371.% rate for his career. He has enough power and bat speed to mitigate that issue -- and we've seen the Cardinals help a player with a similar profile in Jordan Walker succeed this year -- but it will limit his ceiling until he can get his bat on the ball more frequently.
With Walker, Nathan Church, and Bryan Torres penciled in as the starters in the outfield, Pereira will have a decent shot to prove his worth as a fourth outfielder (he's still in his pre-arb years), especially if he can outplay fellow reserve Nelson Velázquez.
