We kept the same filters as always (BA, SLG, wOBA, K %) and added a Hobby Angle for every featured name, plus the full Top-100 call-up tracker.

Hobby Angle
- Lawlar: 2022 Bowman Chrome autos climbed from $90→$115 after Tuesday’s four-hit game; PSA 10 base now $185.
- Mayer: Grand-slam + two-HR game pushed 2021 Bowman Draft Refractor /499 PSA 10s to $260 (up 18%).
- AJ Ewing: Cheap entry for a .497 wOBA.
- Escobar: Clearwater slugger’s 1.100 OPS has breakers chasing his unreleased Bowman Chrome autos; expect Hobby Love Day 1.
- Brito: Quiet prospect but a 9-hit week pushed his 2021 Bowman Sapphire /99 from $6 to $12 — deep-league flip candidate.

Quick Hobby Notes
- Simpson’s 2022 Bowman 1st Chrome autos have moved from $30-50 to $75+ after call-up and those two steals — speed sells. Exciting player to watch with unlikely hobby staying power. We would recommend selling if you are not a fan.
- Luke Keaschall was off to an amazing start, bumped to 3rd in the batting order, before fracturing his forearm. With an extended IL stay coming up, this could give prospectors another opportunity to buy. We are a long-term believer.
