The Nationals are looking in the bargain bin for a veteran starting pitcher. Two options they’re considering are Mark Prior and Jason Jennings, according to MLB.com’s Bill Ladson. The Nats first touched base with Jennings’ agent around November 6th. Prior is a new name for them though.
Jennings has the Royals, Rangers, Rockies, and Mets on his trail as well. As for Prior, the Astros, Reds, Rangers, Phillies, and Padres may be the most interested clubs.
