Debut Announcement and Immediate Context
On Wednesday, May 22, 2026, the New York Mets promoted 24-year-old left-hander Zach Thornton to start against the Washington Nationals at Nationals Park. The promotion was confirmed in a 3 p.m. call on Monday, during which Thornton told his father, Paul, “I’m going.” Paul, recovering from spinal-tumor surgery at Chicago’s Shirley Ryan AbilityLab, traveled with his wife, Julie, to Washington and secured a wheelchair-accessible seat in Section 114.
Journey to the Majors
Undrafted out of high school in 2020, Thornton enrolled at Barton County Community College, posting a 2.63 ERA with 91 strikeouts in 78 2/3 innings as a freshman. A video shared by a friend of his father, a track coach, led to a scholarship at Grand Canyon University, where the Mets selected him in the fifth round of the 2023 draft. In Triple-A, he recorded 13 strikeouts, three runs and three walks over roughly 12 innings, prompting the Mets to choose him over higher-ranked prospects for the major-league start.
Father’s Health Crisis and Rehabilitation
In late winter, Paul Thornton experienced right-side numbness; an MRI on March 22, 2026 revealed a spinal tumor. He underwent tumor-removal surgery on April 2, during which bleeding caused temporary loss of lower-body sensation. Post-operative care at Shirley Ryan included intensive therapy; within weeks he walked 466 feet using a two-wheel walker and aims to walk unaided by the NCAA Track and Field Championships in mid-June.
