BALTIMORE -- Wandy Rodriguez threw 3 1/3 innings and 73 pitches on a rehab assignment at Double-A Altoona on Thursday, and Pirates manager Clint Hurdle said the left-hander felt fine afterward.
But the skipper said they want to see how Rodriguez is doing Friday, since he thinks that might show something else.
Rodriguez (right knee inflammation) has been on the DL since April 21, retroactive to April 20, and Hurdle has a reason for waiting until Friday to check on him.
"The last time this flared up, it flared up the day after he pitched," Hurdle said before Thursday's doubleheader against the Orioles. "We'll know more tomorrow."
Rodriguez has an 0-2 record with a 7.65 ERA in four starts, and he had problems throughout the first month.
He also had an MRI and had fluid drained from his right knee before going on the DL.
Pirates' bullpen well rested for doubleheader
BALTIMORE -- The Pirates came into Thursday's doubleheader in Baltimore with a very rested bullpen thanks to three days off, two of which came from the rainouts on Tuesday and Wednesday.
Pirates manager Clint Hurdle said he'll have plenty of cards to play from the bullpen, something which will help him in both games.
"It's good because you've got a doubleheader … [and] we're in the best shape we could be [in] to go and play at least 18 innings," Hurdle said.
The Pirates will use different pitchers out of the bullpen depending on the situation.
"It's all about where you are in the game," Hurdle said. "We have a certain plan of attack when we're ahead. We have a plan of attack when we're tied, and we have a plan of attack when we're behind by a run. After one run, two runs down, it can switch."
• The Pirates and Orioles cannot add a 26th man to the roster for Game 2 of Thursday's doubleheader, because it's not a split DH. If it was, that option would be available, but Hurdle said he wasn't worried about it.
• Hurdle started the same lineup for Game 1 on Thursday that he was going to use on Tuesday and Wednesday. Ike Davis (first base) started in the two-spot in the lineup for the first time in his career.
• Pittsburgh posted a 15-5 record last season against the American League, the top record in Interleague Play. The Pirates have won nine straight road games vs. AL opponents.
