SAN DIEGO -- Jake Peavy is on the disabled list and Chris Young is likely heading there soon, leaving the Padres without their top two starting pitchers.

Clearly, reinforcements are needed, and that's just what will happen on Thursday, when the Padres will announce that left-handed pitcher Wade LeBlanc will be recalled from Triple-A Portland to make the start on Friday against the Oakland A's.

LeBlanc will be taking the spot in the rotation of Young, who will go on the DL with what is being called inflammation in his right shoulder. Young could miss up to two starts

LeBlanc is 1-4 with a 4.08 ERA with Portland. He was up briefly with the Padres recently but didn't pitch.

On Saturday, the Friars will need a starter for Peavy's turn in the rotation. Peavy went on the DL last week with tendon damage in his right ankle.

Right-hander Walter Silva will be recalled from Triple-A Portland to take Peavy's spot. Silva made two starts for the Padres earlier this season before heading to the DL with a strained right forearm.

Silva began the season as the Padres' fifth starter but suffered the forearm injury in a start against the Mets in April while swinging the bat.

Depending on how much time Young misses, the rotation for a while will be Kevin Correia, Josh Geer -- who gets the start on Thursday against the Mariners -- LeBlanc, Silva and Chad Gaudin.

Pitching matchup
SD: RHP Josh Geer (1-2, 6.14 ERA)
Geer allowed a career-high four home runs in his last start Saturday against the Angels, when he was pressed into duty for Jake Peavy, who went on the disabled list with tendon damage in his right ankle. Home runs have been a big problem for Geer, who has allowed 14 in 58 2/3 innings this season. "I hung a couple of pitches here and there. I worked on staying tall, staying on top of it ... it's one hanger here and there that led to runs," Geer said. "If you are not sharp and leave a pitch up at this level, they can hit them out." This is a lesson Geer is learning, though he did make five starts in September. Geer has always been a guy who pitches to contact and will give up more hits than innings and, by in large, will give up his fair share of home runs.

SEA: RHP Brandon Morrow (0-3, 5.91 ERA)
Morrow makes his second start since being moved back into the rotation. He threw 64 pitches over three innings against the Rockies, which was more than he wanted to throw in such a short amount of time, but surrendered just one run. He still lacks command of his fastball, but is developing a nice slider. His pitch count will be increased to 75 or 80 against the Padres. Morrow has faced them six times in his career and has yet to allow a run.
