MESA, Ariz. — At the end of the line of pitching rubbers and home plates that make up the “12-pac” — a large outdoor bullpen at the Cubs’ spring-training complex — sits a triangular wooden structure supporting a rubber mat-clad wall.
Similar structures have become more common around baseball in recent years, as weighted PlyoCare ball programs, popularized by Driveline, have spread. But this mobile plyo wall came from the mind and hands of James Ogden, the Cubs’ minor-league coordinator of pitching performance.
