The Chicago White Sox and San Diego Padres have agreed to a deal that would send Peavy to the White Sox and four prospects back to San Diego, reports SI.com. The deal only needs approval from Peavy, who has a complete no-trade clause.

Aaron Poreda and Clayton Richards, both highly regarded left-handed pitching prospects, are rumored to be headed to San Diego. The White Sox won't lose shortstop Gordon Beckham, who is their best prospect.

The White Sox may have to exercise Peavy's 2013 option for $22 million for him to approve the trade. Early reports have them not willing to do this.

Some quick thoughts:

• Having Peavy solidifies the White Sox's rotation and raises their profile in the American League Central. After today's 20-1 loss to the Twins, Chicago is 6.5 games out of first, but Peavy gives the White Sox a true ace. Their pitching could use this boost greatly. If this deal goes through, it would be difficult to argue the White Sox aren't the favorite in the division.
• The Padres are showing how desperate they are for salary relief. The club was recently sold and is being rebuilt. Adding Poreda and Richards would give them a huge boost in terms of young pitching, but San Diego should've worked harder to obtain Beckham as the centerpiece of this deal. Watch for Adrian Gonzalez, the co-leader in National League home runs with 15, to be dealt next. His bat could definitely help a contender this season. (Too bad the Padres exercised during the offseason Brian Giles' $9 million option that now looks atrocious.)

Rickie Weeks seemed to finally be putting everything together this season. Willie Randolph worked to "calm" Weeks down in the field. Weeks was also hitting for a respectable batting average with some pop. His running game was a little off, but that's just nit-picking.

But now Weeks is done for the season, writes Tom Haudricourt of the Milwaukee Journal-Sentinel.

The bad news came from Phoenix, where Weeks had traveled to have his injured left wrist examined. An MRI confirmed he has a torn tendon sheath in the wrist, necessitating season-ending surgery Wednesday by specialist Don Sheridan.

In an odd twist of fate, Sheridan performed the same surgery on Weeks' right wrist late in the 2006 season. Brewers trainer Roger Caplinger said the odds of a player suffering that exact injury in the other wrist were incalculable.

"Dr. Sheridan said he's never had a person have this in both wrists in his career," said Caplinger, who said the Extensor Carpi Ulnaris tendon would not stay in place when the sheath is torn.

"The recovery time is four to six months. That's the best guess right now. (Sheridan) will have other information once he gets in there and opens it up."

As for why Weeks might be susceptible to that particular wrist injury, Caplinger said, "He has strong hands, strong wrists. The bat speed he has possibly contributed to that. There's a lot of torque going on there."

Weeks suffered the injury on the final swing of a strikeout to begin the game Sunday against St. Louis. He was removed from the game and it was announced afterward that he was going to Phoenix to see Sheridan.

The Brewers are going to search for a replacement internally before shopping around. Craig Counsell gets first crack at the spot, but he doesn't appear to be the every day player the Brewers need for the remainder of the season.

Highly touted shortstop prospect Alcides Escobar could be called up to play second once he has had a crash course at second in the minors. If Mat Gamel pulls out his best Ryan Braun impersonation at third this season, the Brewers may be able to eat Counsell's lack of production at second.

No matter what happens, the Brewers need their youngsters to step up big time.

Eric Chavez has gained a reputation as an injury-prone player over the last few seasons. His health status has always been reported as a good sign ("Eric Chavez enters this season healthy.") only for it to turn into a punch line ("Eric Chavez hits the disabled list again.")

We may not be seeing much more of Chavez, writes Susan Slusser of the San Francisco Chronicle.

The next time Eric Chavez's back goes out, it will be the end of his career.

"Pretty much game, set and match," the A's third baseman told The Chronicle by phone from his home in Phoenix.

Chavez is rehabbing his most recent back problem in Arizona in the hopes of rejoining the A's on their next homestand. Doctors, however, have told him that a herniated disk in his back could go at any time, even if he sneezes.

If that happens, Chavez will need to have his previously repaired vertebra, the L4-L5, fused with the vertebra that is currently herniated, which is the L3-L4. Another microdiscectomy such as the one Chavez had in October, 2007, is out, because it would leave his spine too unstable, Chavez said.

Spinal fusions don't allow for the type of physical activity performed by pro athletes.

Position players put their back through a tremendous amount of stress. (Go to the batting cages for a day and take swing after swing after swing. How does your back feel the next day?) This is why injuries to the back continue to crop up, even after a player has gotten over a previous injury.

Vladimir Guerrero has a violent swing to be sure, but he's missed time the last several seasons because of back issues. Back injuries just have a way of coming back to haunt hitters.

This definitely isn't good news for Chavez. We should hope he's not ready to quit playing baseball, but his health may dictate that. It seems as if Chavez won't play much longer at the major league level.

Sunday's web gems:

In AHP's highlight of the night, Johnny Damon hits a walk-off home run as the Yankees beat the Twins 3-2 Sunday:

As reported by the AHP blog, Angels pitcher John Lackey was ejected after throwing two pitches in his season debut Saturday. His first pitch was behind the head of Rangers second baseman Ian Kinsler, and the second one plunked Kinsler in the rib cage.

Angels manager Mike Scioscia plans to discuss the matter with MLB, writes Mike DiGiovanna of the Los Angeles Times.

Manager Mike Scioscia plans to contact Bob Watson, baseball's vice president of discipline, rules and on-field operations, and Mike Port, vice president of umpiring, in an effort to get some clarification on rules regarding warnings and ejections.

Last week in Anaheim, before a series between the Angels and Red Sox, umpires put the teams on alert because of the Josh Beckett-sparked benches-clearing incident between the teams the previous time they met, on April 12.

When Boston right-hander Justin Masterson threw a pitch behind the back of Torii Hunter, both benches were warned, meaning another similar pitch would result in the ejection of the pitcher and that pitcher's manager.

But there was no such "heads up" from the umpires before this weekend's Angels-Rangers series and no warning when John Lackey threw his first pitch of the game behind the head of Rangers leadoff batter Ian Kinsler.

When Lackey hit Kinsler with his next pitch, he was ejected by home-plate umpire Bob Davidson.

"We have to get this criteria uniform, because I've seen it happen against us, and a lot of leeway is given, and we didn't get that today," Scioscia said. "As wrong as we know Bob was in his evaluation, it certainly wasn't John's intent to hit Kinsler.

"They gave us a heads up against Boston, the ball goes behind a guy's back, there's a warning. Today, no heads up was given; unfortunately, John's first two pitches, he's trying to go inside and he hits Kinsler. But the intent wasn't there."

Scioscia has said his team doesn't play that way, and I believe him. The Angels have a strong reputation as a good team throughout the major leagues, and it difficult to think Scioscia would tell his pitcher to headhunt to start a game. Why would the Angels want Kinsler on base, especially in front of a power Rangers lineup?

Lackey was also making his major league debut. It doesn't make sense for him to be headhunting in this incident. He's trying to go out there and give his team a few innings, especially with the Angels bullpen pitching as badly as it has been.

Lackey's ejection was a strange one by home-plate umpire Bob Davidson. I don't think the intent to do harm was there.
