Stolen bases rose 40% to their highest level in nearly a quarter-century and scoring increased by 1.1 runs per game. Pitch clock violations averaged 0.74. The big league batting average was .248 through 425 games. Lefties hit .242, up from .229 through April last year. Righties are hitting .250, up from .234.
