In Perez, the Reds land a left-handed reliever with 20 MLB appearances on his resume. He did a lot of starting in the minors but should continue to pitch out of the bullpen for Cincinnati. He is a good bet to make the roster in 2021 as one of the team's southpaws.

In Berryhill, the Astros get a 22-year-old catcher who last played at Single-A Greeneville in 2019. He is probably no more than a backup catcher prospect, but Houston might offer Berryhill a greater opportunity to move up the organizational ladder.

While Perez does have some upside as a fantasy reliever, he should not be drafted in 2021 because his role remains undefined in Major League Baseball. However, keep an eye on him. Meanwhile, Berryhill is likely a few years away from being on the big-league radar, and the jury is still out on his long-range upside.
