A Padres team source indicated Wednesday afternoon that he didn't think the Twins were involved in a prospective deal for Peavy.
San Diego general manager Kevin Towers said Tuesday that any compensation that the Padres receive in a deal for Peavy would mostly be comprised of Major League-ready pitching. Towers said the deal would involve a third team and possibly a fourth team.
The Twins have a number of pitching prospects who could be moved aside, even if they opt not to move several members of their starting rotation.
Philip Humber, 25, was acquired from the Mets in the Johan Santana deal last year. He went 10-8 with a 4.56 ERA last season at Triple-A Rochester. Boof Bonser, 27, started the season in the Twins' rotation, but was later moved to the bullpen. He was 3-7 with a 5.93 ERA.
Bonser and Humber, both right-handers, are out of options.
Other possibilities include 25-year-old right-hander Brian Duensing, who was 5-11 with a 4.28 ERA at Rochester, 23-year-old right-hander Anthony Swarzak, who was 8-8 with a 4.48 ERA between Double-A New Britain and Triple-A and 23-year-old right-hander Kevin Mulvey, who was 7-9 with a 3.77 ERA at Rochester.
The Phillies are also rumored to be interested in DeRosa, and they have some pitching to offer the Padres in a multiteam deal.
J.A. Happ, a 26-year-old right-hander, is thought to be high on the Padres' list of players they like. He was 8-7 with a 3.60 ERA in 2008 at Triple-A Lehigh Valley. San Diego might also have interest in 24-year-old Kyle Kendrick, who was 11-9 with a 5.49 ERA with the Phillies last season.
According to sources, the Phillies might want San Diego outfielder Scott Hairston as they go about trying to fill the void left by free agent Pat Burrell.
