The Cardinals claimed Hampton off waivers from the Nationals on Monday.
Hampton was one of the Yankees' best pitching prospects a few years ago, but he missed all of 2025 following Tommy John surgery and struggled in 2026 upon returning, logging an 8.18 ERA and 56:34 K:BB over 55 innings across three levels in the minors. The 25-year-old has yet to advance past the Double-A level.
