Scouting Report
Updated May 20, 2026
Zach Thornton, the New York Mets' No. 13 prospect, has been called up to the major leagues to fill the rotation void left by Clay Holmes' fractured fibula injury. The 24-year-old left-hander has impressed at both Double-A and Triple-A levels in 2026, striking out 40 batters across 37 innings. He is scheduled to pitch on Wednesday against the Washington Nationals, potentially as a starter or with an opener. Thornton is highly regarded for his exceptional control and command, ranking among the best in minor league baseball. Manager Carlos Mendoza praised his strike-throwing ability and pitchability, particularly against left-handed batters.
