Veteran reliever Andrew Bailey has been scored upon in four of his last five appearances and he has increasingly been used in lower-leverage situations. "We're not giving up on him," Mackanin said. "But he needs to show some improvement." . . . On Tuesday, Vince Velasquez will make his fourth start since returning from the disabled list. He struck out 20 and walked four with a 2.12 ERA in the first three.
