ATLANTA — As they entered the season, the Atlanta Braves were hoping to just hang on through the first month while they waited for Mike Minor and Gavin Floyd to join a depleted rotation. Instead, manager Fredi Gonzalez faces a different problem for the Braves, who were off on Monday: How does he make room for another arm in a rotation enjoying the majors' best opening month in 100 years? There's no weak link as the starters' 1.57 ERA easily leads the majors.
