Silva reportedly mulling Mariners offer

Deal could land free agent righty in Seattle for four years

The Mariners are on the verge of adding a starting pitcher without having to subtract one of their top prospects.

Free agent right-hander Carlos Silva is contemplating a four-year, $44 million offer, which was first reported by Foxsports.com late Tuesday morning.

A Mariners official confirmed that negotiations with Silva are ongoing but would not comment about the contract specifics. Signing Silva would boost Seattle's rotation and allow the club to keep -- for the time being -- right fielder Adam Jones, a former first-round Draft choice and potential star.

Silva, 28, would move into a rotation that includes right-handers Felix Hernandez and Miguel Batista, and left-hander Jarrod Washburn.

The former Twins pitcher became the Mariners primary target on Sunday after Japanese right-hander Hiroki Kuroda signed with the Dodgers -- for about $3 million less than Seattle offered.

Silva spent the past four seasons with the Twins, posting a 47-45 record. He was 13-14 with a 4.19 ERA in 2007. He has a 2-1 record and 3.98 ERA in three starts at Safeco Field in the past three seasons and has won three of his four career decisions against the Angels.

He also is an innings-eater, tossing 203, 188, 180 and 202 innings the past four seasons.

The signing could be finalized and announced by the end of this week.

Meanwhile, the Mariners have been trying to upgrade their starting rotation and have been linked to trade talks with the Orioles for left-hander Erik Bedard. But Jones, 22, who hit 25 home runs at Triple-A Tacoma last season and could be a fixture in the Seattle lineup for years to come, would be included in the trade for Bedard, a price many believe is too high.
