Jon Lester SP OAK 4 Days

Lester worked into the seventh inning Sunday night, surrendering four runs (three earned) on six hits and a walk while striking out five in a 4-3 loss to the Braves.

After three consecutive wins to begin his tenure in Oakland, Lester suffered his first loss with the A's on Sunday night. The 30-year-old lefty has been mostly solid across four starts since going from Boston to the West Coast, posting a 2.93 ERA, 1.08 WHIP and 8.1 K/9 across 27.2 innings. Lester is slated to be back on the bump next weekend versus the Angels.

Lester fanned eight and walked two while allowing just three hits in a complete game shutout against the Twins on Thursday night.

Making only his second start for the A's since being acquired at the July 31 non-waiver trade deadline, Lester had little difficulty with the Twins' lineup Thursday, while affording the A's relief corps a full day of rest heading into Game 2 of the four-game set.

Athletics acquired LHP Jon Lester and OF Jonny Gomes from the Red Sox for OF Yoenis Cespedes.

The A's were unsatisfied with their rotation even after acquiring Jeff Samardzija (and Jason Hammel) from the Cubs, so they got a little more creative and picked up the top ace on the trade market. Lester can become a free agent after the 2014 World Series and is highly doubtful to re-sign with Oakland, but he'll give the club a big boost down the stretch and into October. The 30-year-old left-hander was sporting a 2.52 ERA, 1.12 WHIP, and 149/32 K/BB ratio in 143 innings this season for Boston. Now he moves to the most pitcher-friendly park in MLB.

WEEI's Alex Speier reports that the A's have acquired left-hander Jon Lester and outfielder Jonny Gomes from the Red Sox for Yoenis Cespedes.

Without many elite-level prospects remaining in the wake of the Jeff Samardzija and Jason Hammel trade, the A's had to get creative to work out a deal for Lester. And this sure is creative. Cespedes has big-time power, a huge throwing arm, and is under contractual control through 2018, so it's a big piece to give up. Lester gets a massive fantasy boost with the move to pitcher-friendly Oakland.

The Cardinals and Pirates are the two teams "pushing hardest" for Jon Lester, sources tell FOX Sports' Ken Rosenthal and Jon Morosi.

Rosenthal notes that the Dodgers remain involved as well. The Cardinals made a move for a starter on Wednesday, acquiring Justin Masterson from the Indians, but they remain interested in Lester as more impactful starter to pair with Adam Wainwright. Lester would immediately become the Pirates' ace down the stretch. Lester is a free agent after the season.

FOX Sports' Ken Rosenthal reports that a trade sending Jon Lester to the Orioles is "not close."

Rosenthal didn't rule out something getting done, but it appears the two sides aren't as close to crossing the finish line as previously reported. MLB.com's Peter Gammons adds that the Red Sox still have "plenty" of alternatives if they're not able to work something out with the O's.

MLB.com's Brittany Ghiroli reports that the Orioles are close to acquiring Jon Lester from the Red Sox.

The Boston Globe's Pete Abraham is also hearing the deal is close and says the Red Sox will receive a pitcher in return. He mentions Miguel Gonzalez, but he would figure to be a secondary part of the deal. It appears that Lester will get to stay in the AL East and has said in the past that he would still consider re-signing with the Red Sox.

FOX Sports' Jon Morosi reports that the Cardinals could still go after Jon Lester even after the acquisition of Justin Masterson.

Morosi says that they would have to be willing to give up Shelby Miller to do it. It's certainly possible that the Red Sox have floated this information to Morosi in order to drive up Lester's price with other teams. On the other hand, St. Louis didn't have to surrender any of their top prospects to get Masterson, so we can't rule anything out.

MLB.com's Peter Gammons reports that the Dodgers are no longer pursuing Jon Lester, David Price and Cole Hamels.

The Dodgers are refusing to give up Joc Pederson, Corey Seager or Julio Urias in any deal, which makes acquiring one of the aforementioned aces an impossibility. Gammons said they're now focused on adding a back-end starter and bullpen help. With the Cardinals also out of the picture, it appears the Lester market might be down to the Pirates and A's.

Juan C. Rodriguez of the South Florida Sun Sentinel reports that the Marlins are "not completely" out of the Jon Lester sweepstakes.

Rodriguez says the Marlins will not trade Andrew Heaney for Lester, but it sounds like they might be willing to consider just about anyone else in their system. For what it's worth, president of baseball operations Michael Hill said the club is "not going to be short-sighted" in any deals.
