tiny sample, loud pop
In the 2026 season, Columbia outfielder Jack McWilliams flashed real juice in a very small sample: .500 batting average, 1.100 slugging, two homers, four RBIs, and a perfect 1.000 fielding percentage in two chances[1][2]. The differentiator is obvious—his bat speed and left-handed power played immediately, with both of his first two collegiate homers coming in clutch spots, including a two-run blast and a late RBI knock[1][4][13]. Columbia’s staff also views him as a true two-way competitor from his San Marcos/Cathedral Catholic background, and his size (6-3, 190) fits the mold of a projectable corner-outfield bat with upside[5][6].
