FOXSports.com's Ken Rosenthal reports the Rangers have yet to make an offer for free agent Roy Oswalt. Like the Cardinals, the Rangers have expressed interest but are ''not an obvious fit'' on paper. Oswalt recently turned down a one-year, $10 million contract from the Tigers. However, it is not yet known whether he'd be willing to take a hometown discount to pitch for Texas.

Cardinals GM John Mozeliak told Matthew Leach of MLB.com that rumors of an impending deal with free agent Roy Oswalt are "not true." Multiple reports have suggested otherwise. MLB Network reported Friday that a deal between the two sides was ''very close,'' and ESPNBoston.com has since reported that Oswalt has "elected to stay in the National League" and is "likely" to sign with the Cardinals "soon." Other teams believed to be in the running for Oswalt include the Rangers, Astros, and Red Sox.

Roy Oswalt reportedly turned down a one-year, $10 million contract from the Tigers, according to Jon Heyman of CBSSports.com. Heyman cites an unnamed source on the financial terms, but this confirms an earlier CBS report that Oswalt in fact turned down an opportunity to play in Detroit. The Tigers have at least one open spot remaining in their starting rotation, but may now look to stay in-house rather than add an established starter through trade or free agency.

Roy Oswalt's agent, Bob Garber, told Tim Dierkes of MLB Trade Rumors that there is "no chance" of his client moving to the bullpen. Garber declined to comment on anything team-specific, but his stance indicates that the Cardinals are indeed the favorite to sign Oswalt. Assuming a deal gets done, Kyle Lohse and Jake Westbrook will be candidates to be moved from the starting rotation.

A major league source tells FOXSports.com's Ken Rosenthal that Roy Oswalt was ''not close to signing a deal with the Cardinals'' late Friday night. This corroborates a report from the St. Louis Post-Dispatch that insists no deal is in place. The Cardinals' motives for signing Oswalt are unclear, as both Kyle Lohse and Jake Westbrook have full no-trade clauses and limited trade value. Lohse will earn $11.875 million in 2012. Westbrook is set to make $8.5 million.

Updating a previous item, Gordon Edes of ESPNBoston.com reports that Roy Oswalt has elected to stay in the National League and is likely to sign with the Cardinals "soon." Edes previously reported that Oswalt was headed to the Cardinals, but he was told by a source that a deal is "not 100 percent." Meanwhile, Joe Strauss of the St. Louis Post-Dispatch reports that the Cardinals are insisting no deal is in place. Keep in mind that the 34-year-old right-hander has a history of back problems, so it's possible that some formalities stand in the way of an agreement. Stay tuned.

Gordon Edes of ESPNBoston.com reports that the Cardinals and Roy Oswalt have agreed to a contract. Jim Duquette of MLB Network Radio on Sirius XM first indicated that the two sides were close. No word on the financial terms, but we'd suspect it's a one-year deal in the $5-10 million range, possibly with some performance-based incentives. The 34-year-old Oswalt was limited to 23 starts last season due to a back condition, posting a 3.69 ERA and 93/33 K/BB ratio across 139 innings. It will be interesting to see what happens with the Cardinals' starting rotation, as Kyle Lohse and Jake Westbrook are both owed big money this season and have no-trade clauses in their contracts.

Joe Strauss of the St. Louis Post-Dispatch confirms the Cardinals' interest in Roy Oswalt. Jim Duquette of MLB Network Radio on Sirius XM reported Friday evening that the Cardinals and Roy Oswalt were close to an agreement. Strauss didn't specify whether the two sides were close to a deal, but wrote that the veteran right-hander is expected to make a decision soon. The Red Sox, Astros and Rangers are also reportedly in the mix for his services.

ESPN's Buster Olney reports that the Red Sox have a one-year offer out to Roy Oswalt for around $5 million. The Red Sox also have an offer out to Edwin Jackson, though the specifics aren't known. As for Oswalt, he would reportedly prefer to pitch for either the Cardinals or the Rangers. Joe Strauss of the St. Louis Post-Dispatch reported Wednesday night that St. Louis made an offer to Oswalt earlier this winter "approaching $5 million," but believes that the Rangers will ultimately step up with a contract in the $7-8 million range.
