Yesterday, reports indicated that the Orioles and Mariners have both inquired on Red Sox ace Jon Lester, but the Sox are likely to take any decision down to the wire. Earlier this morning, we noted that Gordon Edes of ESPNBoston.com heard there was less than a 50 percent chance Lester is dealt based on current talks, but offers are expected to increase in the coming days.

We’ll keep track of the rest of Tuesday’s Lester-related rumors in this post…

• A source with direct knowledge of the situation says that there are six clubs still in on Lester, per Edes (via Twitter): the Dodgers, Cardinals, Pirates, Blue Jays, Orioles, and Athletics.
• At present, the Red Sox have not received a trade proposal that the club is satisfied with, tweets Abraham. Multiple reports have indicated that no trade was in place when Lester was scratched from his start. At the moment, the Cardinals, Dodgers, and Pirates are all in the mix for Lester, tweets Rosenthal.
• The Brewers are “not on” Lester, tweets Ken Rosenthal of FOX Sports.
• Lester has been scratched from his start tomorrow, manager John Farrell tells reporters, including Jason Mastrodonato of MassLive.com (via Twitter). A rival GM tells Rob Bradford of WEEI.com (Twitter link) that it appears a deal will be in place tonight or tomorrow morning.
• The division-rival Jays and Orioles seem out of the running for Lester at this point, per Bradford (Twitter links). A team source rejected the suggestion that the Dodgers would offer top prospect Joc Pederson for Lester, Saxon reports.
• If the Pirates make a deal for Lester, it will have to occur before his start tomorrow so he can take his next turn for Pittsburgh, reports MLB.com’s Tom Singer. The Bucs are not willing to part with prospects Tyler Glasnow, Nick Kingham, Jameson Taillon, Josh Bell, or Austin Meadows in a deal. But the team would consider dealing Alen Hanson or JaCoby Jones, and Singer says that outfielder Jose Tabata is a “wild card” in discussions, which could potentially expand to include Mike Carp or one of several Boston relievers.

Earlier Updates

• The Red Sox were never given a “figure … on what it would have taken to sign” Lester, a source tells Nick Cafardo of the Boston Globe (via Twitter). But while Lester and his representatives never formally made an offer to the Red Sox, both sides exchanged numbers and understood their respective parameters, Rob Bradford of WEEI.com reports.
• The Red Sox have enhanced leverage regarding Lester because he could tip the balance in the NL Central, if not also the rest of the National League, Joel Sherman of the New York Post writes. Sherman discusses the possibility of the Dodgers, Cardinals, Pirates, and Brewers making the move for a rotation upgrade. Boston is “at least considering” attempting to deal and later re-sign its staff ace, Sherman adds.
• Sox manager John Farrell says that the club still has Lester penciled in to start, but is prepared to use Brandon Workman in his place if Lester is dealt, as Pete Abraham of the Boston Globe tweets.
• The Dodgers are not close to any major deals at the moment and adding Lester “appears … unlikely,” tweets Mark Saxon of ESPNLosAngeles.com. Nevertheless, Los Angeles appears on top of the list of likeliest suitors for the Boston lefty, as handicapped by Jon Heyman of CBSSports.com.
• The Pirates are emerging as a dark-horse to acquire Lester, report Jeff Passan and Tim Brown of Yahoo Sports. One possible centerpiece of such a deal would be well-regarded prospect Josh Bell, the Yahoo writers add. A deal with the Pirates would not necessarily involve Bell, however, Gordon Edes of ESPNBoston.com tweets.
• The Red Sox are actively taking offers and preparing to deal Lester, a National League GM tells Pete Abraham of the Boston Globe (Twitter link). Abraham says it is difficult to see Lester taking his start tomorrow for Boston.
• Jim Bowden of ESPN and MLB Network Radio reports (via Twitter) that the Blue Jays, Mariners, Brewers, Cardinals, Dodgers, Orioles and Marlins are all currently in on Lester. The Marlins are certainly a new addition to the mix, although that would line up with Buster Olney’s report from earlier today pegging them as a potential surprise candidate for some starting pitchers. Miami has a number of high-end prospects, and Lester’s remaining $4.48MM in salary might not be too overwhelming.
• Andy Martino of the New York Daily News hears the same as Olney did earlier this morning (Twitter link): There’s “little doubt” in the industry that Boston will move its ace. Rival clubs are expecting a trade.
• Lester’s agent, Seth Levinson of ACES, denied a previous report that his client’s asking price in extension talks motivated the Red Sox to trade him, reports Gordon Edes of ESPNBoston.com. Unsurprisingly, Levinson shed no further light on any extension talks with Lester: “The discussions we had with the Red Sox were confidential and will remain that way,” Levinson said to Edes in an email.
• Sean McAdam of CSNNE.com adds some new teams to the Lester mix, as he reports that the Athletics, Blue Jays and Braves have all called to inquire on the BoSox ace. Of those teams, Toronto is being the most aggressive in its pursuit, a source tells McAdam. The Sox are willing to move him to the division-rival Jays or Orioles, according to McAdam’s source. Boston is still seeking multiple prospects in return, specifically one elite prospect — McAdam uses Oscar Taveras, Joc Pederson and Corey Seager as examples — and at least one more lesser prospect. Interestingly, McAdam notes that the Red Sox will not consider trading Lester to the Yankees.
• The Brewers have spoken to the Sox about Lester, reports Jon Heyman of CBS Sports. Milwaukee was said to have asked the Rays about David Price as well, but Price might not be dealt now, and Lester would cost less to acquire. Heyman notes that Milwaukee has top pitching prospect Jimmy Nelson to offer as a centerpiece and has a deeper farm system than it has in prior years. Nelson ranked 38th on Baseball America’s midseason list of the game’s Top 50 prospects, and MLB.com ranked him 53rd on their midseason Top 100.
