5 Las Vegas Athletics Prospects Who Could Define the 2028 Roster

When the Las Vegas Athletics open their $2 billion Strip ballpark in 2028, the roster that takes the field could be one of the most exciting in franchise history. Here are five prospects building toward that moment.

1. Leo De Vries, SS — The 4th-ranked prospect in all of baseball according to MLB Pipeline, De Vries was acquired from the Padres as the centerpiece of the Mason Miller trade. At just 19 years old, he has one of the highest ceilings of any prospect in the game, with two-way impact potential and All-Star upside. He is the future of this franchise.

2. Gage Jump, LHP — Jump's fastball now sits in the mid-90s with plus carry, paired with a sweeper that's becoming a genuine put-away pitch. FanGraphs' ZiPS projections believe Jump has a real shot to be the best pitcher on the A's staff within 18 months.

3. Jamie Arnold, LHP — The A's 2025 first-round pick brings a polished arsenal that has scouts excited about his big league timeline. Arnold is considered one of the faster-moving arms in the system.

4. Joshua Kuroda-Grauer, SS/2B — An under-the-radar name worth knowing. FanGraphs' defensive metrics love his work up the middle, and he projects as a potentially strong pairing with Jacob Wilson.

5. Wei-En Lin, LHP — The 23-year-old Taiwanese lefty pitched across three levels as a teenager, posting 12.1 strikeouts per nine innings. He's one of the most intriguing arms in the system heading into the second half of 2026.

The pipeline is real. By 2028, this could be a very dangerous team.
