Angels acquired LHP Joe Thatcher and OF Tony Campana from the Diamondbacks in exchange for OF Zach Borenstein and RHP Joey Krehbiel.

The veteran southpaw makes for a nice addition to the Angels bullpen which was lacking in quality left-handed arms. He has done a nice job for the D'Backs this season, posting a 2.63 ERA, 1.08 WHIP and 25/3 K/BB ratio over his 24 innings of work. Despite adding Thatcher and Jason Grilli this week, the Angels are rumored to still be in the market for further bullpen upgrades.

According to Ken Rosenthal of FOX Sports, the Angels have agreed to a deal to acquire Joe Thatcher and Tony Campana from the Diamondbacks.

No word yet on the potential return package that the Diamondbacks would be receiving in the trade. There were rumblings late Friday that the Angels were interested in the veteran southpaw, and it appears as though they worked things out quickly. He'll add a much-needed left-handed weapon to manager Mike Scioscia's bullpen.

Ken Rosenthal of FOX Sports reports that the Angels are interested in acquiring a left-handed reliever and are believed to be interested in Diamondbacks southpaw Joe Thatcher.

The 32-year-old is enjoying a fine season in the desert, posting a 2.63 ERA, 1.08 WHIP and 25/3 K/BB ratio over his 24 frames. He remains one of the top left-handed relievers expected to be available via trade.

Diamondbacks avoided arbitration with LHP Joe Thatcher by agreeing to a one-year, $2.375 million contract.

Thatcher was arbitration-eligible for the final time this winter. The left specialist posted a 3.20 ERA over 72 appearances for the Padres and D'Backs last season.

Ben Nicholson-Smith of Sportsnet.ca believes it's unlikely that Joe Thatcher will be non-tendered by the Diamondbacks.

Thatcher struggled mightily during his time with the Diamondbacks after a mid-season trade, posting a 6.75 ERA, 1.93 WHIP and 7/6 K/BB ratio over 9 1/3 innings. He remains a reliable and effective option out of the bullpen however, and still just 32-years-old, should have plenty of good innings left in him.

ESPN's Jayson Stark reports that the Padres are more likely to deal Joe Thatcher than Luke Gregerson.

Furthermore, Stark hears that the Padres are declining any offers for their outfielders. Finally back to form following shoulder issues, Thatcher has a 2.10 ERA and 29/4 K/BB ratio over 30 innings this season. Left-handed relievers have a lot of value in this market, so the Padres could fetch a nice prospect in return.

FOX Sports' Jon Paul Morosi reports that the Braves are interest in Joe Thatcher.

The Braves are sure to add a left-handed reliever at the deadline, and it's no surprise Thatcher is on their watch list. The southpaw holds a 2.25 ERA this season and has left left-handed batters to a .206/.266/.315 batting line during his career. He's making $1.35 million in 2013 and will be arbitration-eligible for a final time over the winter.

Joe Thatcher earned his fifth hold by tossing two-thirds of a scoreless inning against the Cardinals on Monday night.

When healthy, the southpaw has been terrific for the Padres. Between 2009-2011, he posted a 2.66 ERA, 1.18 WHIP and 10.9 K/9 rate. This year he is 1-0 with a 2.13 ERA, 1.26 WHIP and 10/1 K/BB rate over 21 appearances. As an effective LOOGY who calls PETCO home, Thatcher is a solid middle reliever in deeper NL-only formats.

It was Thatcher's second year of arbitration eligibility. When healthy, the southpaw has been terrific for the Padres since 2009, posting a 2.66 ERA, 1.18 WHIP and 10.9 K/9 rate. He's coming off of arthroscopic surgery on his right knee but is expected to be fine for spring training.

Thatcher went on the DL last month with tendinitis in the knee, but he soon developed sharp pain after that. He did say it's been "a lot better" in recent days to the point where he still thinks he could return later this season. Even if he does come back this year, Thatcher will have surgery over the offseason to address the issue.

Padres placed LHP Joe Thatcher on the 15-day disabled list, retroactive to July 26, with tendinitis in his right knee.

Thatcher sat out all weekend because of the knee discomfort and hadn't made enough progress by Monday afternoon. The 30-year-old left-hander has posted a 3.42 ERA and 1.29 WHIP in 26 1/3 innings this season. He should be back within three weeks.

Joe Thatcher was unavailable for a second straight game Saturday due to a sore right knee.

The Padres don't think he'll need a stint on the disabled list, but it's not clear when he'll be ready to pitch again. Thatcher holds a 3.42 ERA and 1.29 WHIP while striking out over a batter per inning in 40 games for the Pads this season.

The Padres plan to limit Joe Thatcher's workload during the early days of camp.

Thatcher has begun the season on the disabled list in each of the past two years due to shoulder injuries (and even required surgery last May), so the hope is that the lighter workload will lead to less complications. "I've always gone to spring training thinking I had to impress everyone right away," said Thatcher. "And it's kind of against my nature to approach it any other way. But it's nice to have them know what they think I can do and be able to ease into it." If healthy, Thatcher should open the year as the Padres' primary left-handed specialist.

The Padres and LHP Joe Thatcher avoided arbitration by agreeing to a one-year, $700,000 contract.

Thatcher pitched only 10 innings last season due to a shoulder injury. He was dominant in 2010 and 2009, however, and will try to bounce back this year with better health.

Padres manager Bud Black said Friday that Joe Thatcher (shoulder) will be used in lower leverage situations in order to "get his feel back on the ground."

Thatcher, who underwent shoulder surgery in May, was activated from the disabled list Thursday. The veteran left-hander hasn't pitched in the majors this season, but has a 2.14 ERA and 100 strikeouts over 80 innings since the start of 2009.
