Wandy Rodriguez received a platelet-rich plasma injection on Monday for his injured left elbow. Rodriguez will need at least three more weeks of rest, recovery and rehab. The veteran left-hander has been sidelined since early June and is not going to return to the Pirates' starting rotation until after the All-Star break. He had a cool 3.59 ERA, 1.12 WHIP and 46/12 K/BB ratio in 62 2/3 innings before developing his elbow issues.
