KISSIMMEE, Fla. — Rookie right-handers Randall Delgado and Julio Teheran, locked in competition for the fifth spot in the Braves rotation, each gave up a pair of runs in the Atlanta's 4-3 spring training loss to St. Louis. Delgado struck out five and walked three in five innings, while Teheran fanned four and gave up two walks in four innings. "I'm getting better every start," said Delgado, who regretted only one pitch.
