Spring Training Sleepers: 3 MLB Prospects Whose Cards Could Skyrocket by June

The crack of the bat is back in Florida and Arizona, and for collectors, that sound means one thing: Prospecting Season. While everyone is chasing the established stars, the real money in the 2026 hobby is made by identifying the "breakout" players before they get the call to the Show. If you’re looking to add some high-upside plays to your box, keep an eye on these three names currently tearing up Spring Training:

1. JJ Wetherholt (Cardinals SS) The former WVU legend is no longer a secret in Morgantown, but his card market is just starting to heat up nationally. After a monster 2025 in the minors, Wetherholt is showing elite plate discipline this spring. His 1st Bowman Chrome Autographs are the "blue chip" investment for any West Virginia-based collector.

2. Walker Jenkins (Twins OF) Jenkins has "five-tool superstar" written all over him. With the Twins leaning into a youth movement this year, Jenkins is poised to be the face of the franchise. His prices are already high, but if he breaks camp with the big league club, those "Base Chrome" cards you have in your common bins will suddenly become $20 bills.

3. The "Pitching Ninja" Favorites Watch the velocity charts. Any young arm touching 101 MPH this spring will see an immediate 20–30% bump in card prices on eBay. We have a fresh stock of 2026 Topps Series 1 in-store—now is the time to rip and flip before the season-opening hype settles.

Pro Tip: Don't just buy the hype. Check the "K-rate" (strikeout rate). Players who control the zone in the spring are the ones who stay consistent in the summer.
