The news was first reported in the Los Angeles Times. Weaver's younger brother, Angels right-hander Jered Weaver, told the paper that the Nationals and Cardinals were in the mix for Jeff's services.
According to one source, the only way Weaver would become a member of the Nationals is if he agrees to a less expensive contract. Weaver is represented by agent Scott Boras, who is known to get top dollar for his clients.
"[The Nationals] are willing to give Jeff a chance, but it has to be [on their] terms," the source said.
Weaver is coming off one of his worst seasons in the big leagues. He went 7-13 with a 6.20 ERA with the Mariners. During his nine-year career, Weaver is 93-114 with a 4.72 ERA and is famous for helping the Cardinals win the World Series in 2006.
The Nationals' interest in Weaver comes at a time when they don't know the status of right-hander Shawn Hill, their projected Opening Day starter. Hill has been experiencing tightness in his right forearm, but he played catch on Tuesday without experiencing any pain.
