After bailing the White Sox out in the eighth, Javy Guerra took a blown save and a loss while giving up two runs in the ninth Wednesday against the Red Sox.

Jake Petricka struggled after coming in with two outs in the eighth, retiring none of the four hitters he faced. That led to Guerra coming on with men on second and third and two outs in a one-run game. He got Mike Carp to ground out, but then he hit a batter, gave up an RBI double and surrendered a game-winning single in the bottom of the ninth. It'd seem to bode well for Zach Putnam getting the White Sox's next save chance.

White Sox purchased the contract of RHP Javy Guerra from Triple-A Charlotte.

He'll take the place of the injured Matt Lindstrom (ankle) on the active roster. Guerra, 28, had a 2.33 ERA and 11/8 K/BB ratio in 19 1/3 innings at the Triple-A level.

White Sox sent RHP Javy Guerra outright to Triple-A Charlotte.

Guerra had been claimed off waivers from the Dodgers on Wednesday, but he won't be part of the White Sox' Opening Day roster. The 28-year-old has enjoyed some success in the majors in the past but held a 6.75 ERA over just nine appearances for Los Angeles last season.

White Sox claimed RHP Javy Guerra off waivers from the Dodgers.

Guerra was designated for assignment by the Dodgers earlier this month. The 28-year-old has enjoyed some success in the majors in the past, so it's a worthwhile gamble for Chicago.

Chris Cotillo of MLB Daily Dish reports that the Dodgers are receiving significant interest in Javy Guerra and are expected to trade him soon.

Guerra was designated for assignment earlier in the week to clear a spot on the 40-man roster. The former closer has an electric arm, and should appeal to many teams with deficiencies in the back end of their bullpens.

Javy Guerra is expected to be claimed off waivers or traded, reports the MLB Daily Dish's Chris Cotillo.

The former closer entered last season having put up a 2.45 ERA, 1.33 WHIP and 75/41 K/BB ratio over 91 2/3 innings the previous two seasons while saving 29 games for the Dodgers, but 2013 turned into a nightmare. He posted a 6.75 ERA and 12/6 K/BB ratio over 10 2/3 innings before Los Angeles banished him to the minors for good in May. The 28-year-old, who was designated for assignment on Sunday, hasn't even accrued two service years yet. The interest he's generating isn't a surprise.

Dodgers designated RHP Javy Guerra for assignment

These are the tough decisions that the Dodgers have to make with a bullpen stockpiled with talent. The 28-year-old hurler struggled in 2013, but posted a 2.45 ERA, 1.33 WHIP and 75/41 K/BB ratio over 91 2/3 innings the previous two seasons while saving 29 games for the Dodgers. He should attract plenty of interest from around the league.

Dodgers optioned RHP Javy Guerra to Triple-A Albuquerque.

Peter Moylan has replaced him on the active roster. Guerra has a 6.75 ERA and 12/6 K/BB ratio over 10 2/3 innings with the Dodgers this season and figures to get another shot in the bullpen before long.

Dodgers recalled RHP Javy Guerra from Triple-A Albuquerque.

Guerra failed to make the Opening Day roster despite having put up a 2.45 ERA over the last two seasons for the Dodgers. The former closer was pitching in Albuquerque's rotation, holding a 4.02 ERA over four starts. He'll work in long relief.

Javy Guerra is in the starting rotation with Triple-A Albuquerque, but only to be stretched out to about three innings.

In other words, the Dodgers are looking at him as long man out of the bullpen. Guerra didn't make the Opening Day roster, but he should be back in the majors before long.

Dodgers optioned RHP Javy Guerra to Triple-A Albuquerque and reassigned RHP Juan Abreu to minor league camp.

Guerra was the Dodgers' Opening Day closer last season, but fell behind in camp due to injuries and will now be stretched out as a long reliever in the minors. A non-roster invite, Abreu should continue to serve as organizational depth.

Javy Guerra will not pitch for Mexico in the World Baseball Classic due to liability issues resulting from his offseason shoulder surgery.

The Dodgers are surely relieved. Guerra has made two scoreless appearances for the club this spring, showing that the shoulder appears to be healthy. He should fill a middle relief role this season.

Javy Guerra has been named a late addition to Team Mexico's roster.

The late addition was due to Team USA member Chris Perez's injury, which forced him to drop out of the competition. David Hernandez then left Team Mexico to join Team USA, opening up a spot on Team Mexico's roster. The 27-year-old righty was supplanted by Kenley Jansen as the Dodgers closer last season, and with the addition of Brandon League Guerra will likely fill a middle relief role for the team in 2013.

Javy Guerra (oblique) underwent arthroscopic surgery on his right shoulder Friday and is expected to begin an throwing program in six weeks.

As long as he doesn't suffer any major setbacks, he should be fully recovered and ready to go for spring training. With Guerra, Kenley Jansen and Brandon League, the Dodgers should boast a terrific bullpen.

Dodgers recalled RHP Javy Guerra from Triple-A Albuquerque.

It was a very short stint on the farm for Guerra, who was demoted on August 21. He owns a 2.66 ERA, 1.50 WHIP and 37/22 K/BB through 44 innings this season, and should easily work his way back into a setup role.

Dodgers optioned RHP Javy Guerra to Triple-A Albuquerque.

Guerra hasn't allowed a run since July 26 and is sporting a superb 2.66 ERA through 44 innings this season. He should be brought back up within the next few weeks.

Dodgers placed RHP Javy Guerra on the bereavement list.

Guerra will take a bereavement leave to be with his father, who is scheduled to undergo open-heart surgery Saturday in Mexico. He likely won't return until Monday, at the earliest.

Dodgers activated RHP Javy Guerra from the 15-day disabled list.

He'll replace the injured Dee Gordon (thumb) on the active roster. Guerra underwent knee surgery one month ago, but didn't have any issues during his minor league rehab assignment. He'll return to a 3.38 ERA over 24 innings and will set up for closer Kenley Jansen.

Javy Guerra (knee) allowed one run on one hit in his rehab debut Sunday at High-A Rancho Cucamonga.

Guerra will make another appearance Tuesday before moving on to a higher level of the Dodgers' minor league system. He could be back in the bigs by the end of this week, but Javy will be returning to a setup role.

Javy Guerra (knee) will make appearances Sunday and Tuesday at High-A Rancho Cucamonga.

Assuming all goes well with those outings and he doesn't experience any renewed soreness in his surgically-repaired knee, Guerra could be cleared to rejoin the Dodgers bullpen by next weekend. He'll remain in a setup role, however, with Kenley Jansen currently dominating as closer.
