Gutierrez signed a minor-league contract with the Nationals on Sunday, Steve Adams of MLB Trade Rumors reports.

Gutierrez, who was released by the Phillies earlier this month, has supplied a 3.66 ERA and 42:18 K:BB ratio across 51.2 innings at the Triple-A level this season. He didn't receive a promotion to the big club as quickly as expected while he was in the Philadelphia organization, but the 32-year-old is hoping to latch on with the playoff-contending Nationals at some point later this season if he continues to excel at Triple-A Syracuse.

Gutierrez signed a minor-league contract with the Phillies on Monday. He will report to Triple-A Lehigh Valley.

Gutierrez, who was released by the Giants' organization earlier this season, struggled at Triple-A Sacramento, sporting a 4.39 ERA across 26.2 innings. However, he has proven himself a decent option out of the bullpen at the major league level in the past. He made 61 appearances for the Giants in 2014, holding a 3.96 ERA with a 44:16 K:BB ratio. He should provide organizational depth for the Phillies' bullpen.

The Giants designated Gutierrez for assignment Thursday.

Gutierrez posted a 3.12 ERA, .228 BAA and 10 holds in the first half of 2014 but pitched almost exclusively in low-leverage situations after the All-Star break. He still finished with 61 appearances, fifth-most on the team, but clearly the Giants had no intention of going to arbitration with the 31-year-old.

Gutierrez (biceps) saw his first action since experiencing pain in his biceps August 24. He gave up a run over his only inning of work in the loss to the Rockies on Wednesday.

Prior to the game, Gutierrez received a cortisone shot in his arm to help alleviate the pain. He apparently felt good enough to play, and the Giants wouldn't have pushed him without knowing that he was healthy due to having a deep bullpen with rosters expanding this week.

Gutierrez received a cortisone shot in his right biceps last Thursday and remains in the recovery process, Hank Schulman of the San Francisco Chronicle reports.

This would help explain why Gutierrez hasn't seen any usage out of the bullpen since Aug. 24. With the Giants bolstering their relief corps with a slew of September call-ups, Gutierrez won't be rushed back to action until the pain in his biceps fully dissipates.

Gutierrez surrendered five runs on five hits and a walk over 1.1 innings against the Nationals on Sunday.

Gutierrez was one of several Giant relievers that couldn't stop the bleeding and preserve the win for Ryan Vogelsong. The 31-year-old journeyman was a revelation for the Giants early in the season, but he has fallen apart in August, posting a 7.11 ERA in 10 appearances.

Giants purchased the contract of RHP J.C. Gutierrez from Triple-A Fresno.

Gutierrez held a 1.69 ERA over 10 appearances this spring to lock up a spot. He'll work the middle innings.

Giants signed RHP J.C. Gutierrez to a minor league contract with an invitation to spring training.

Gutierrez was non-tendered by the Angels in December after posting a 4.23 ERA and 45/20 K/BB ratio over 55 1/3 innings at the major league level last year. The 30-year-old could surface in the Giants' bullpen at some point in 2014.

Angels non-tendered RHP J.C. Gutierrez.

It comes after he was designated fora assignment last week. The right-hander posted a 4.23 ERA over 55 1/3 innings of work this past year and might have to settle for a minor league deal this winter.

Angels designated RHP J.C. Gutierrez for assignment.

The move was made to clear room for newly signed reliever Joe Smith on the 40-man roster. The Angels claimed the 30-year-old Gutierrez off waivers from the Royals in July, and the right-hander posted a 4.23 ERA over 55 1/3 innings of work this past year.

J.C. Gutierrez has been unavailable this week due to a biceps injury.

Gutierrez is only expected to be out a few more days. He'll return to a middle releif role when healthy.

Angels claimed RHP J.C. Gutierrez off waivers from the Royals.

Gutierrez was designated for assignment 10 days ago after posting a 3.38 ERA and 17/8 K/BB ratio over 29 1/3 innings. He should be able to help in middle relief.

Royals designated RHP J.C. Gutierrez for assignment.

Gutierrez has pitched pretty decently for the Royals, posting a 3.38 ERA and 1.30 WHIP, but he was the low man on the totem pole in the bullpen. It's possible he could draw interest on waivers.

J.C. Gutierrez has earned the final spot in the Royals' Opening Day bullpen.

Gutierrez has struck out 10 batters and issued only two walks in 12 innings this spring in the Cactus League. The right-hander should do fine in a middle relief role.

Royals purchased the contract of RHP Juan Gutierrez from Triple-A Omaha.

The 29-year-old right-hander had an ugly 8.18 ERA in 11 innings this past season for Omaha. Gutierrez seems doubtful to crack the Royals' 2013 Opening Day roster.

Royals re-signed RHP Juan Gutierrez to a minor league contract.

Gutierrez underwent Tommy John surgery in September and likely won't contribute until 2013. The 28-year-old right-hander holds a career 4.79 ERA and 1.42 WHIP, but also an 8.2 K/9 rate. He'll be under team control through 2015.

Diamondbacks released RHP Juan Gutierrez.

Gutierrez underwent Tommy John surgery last month, and evidently the D'Backs didn't want to wait until 2013, when he will likely be ready to contribute again. The 28-year-old right-hander holds a career 4.79 ERA and 1.42 WHIP, but also an 8.2 K/9 rate. As a hard-thrower that won't hit free agency until 2015, some other team will give him a shot.

Juan Gutierrez will undergo Tommy John surgery on September 6.

Gutierrez was originally placed on the disabled list in late-May with right shoulder inflammation, but his elbow has emerged as the bigger issue. The 28-year-old right-hander will now be sidelined for most, if not all, of the 2012 season.

Diamondbacks manager Kirk Gibson has revealed that Juan Gutierrez is also dealing with a sore elbow in addition to the shoulder ailment that landed him on the disabled list.

Gutierrez has been sidelined since mid-August and has yet to begin a throwing program. His return date is totally up in the air at this point.
