Mateo signed a one-year contract extension with the Hanshin Tigers, the Japan Times reports.

EDGE Analysis

Mateo had 20 saves last year for Hashin with a 1.80 ERA and 9.2 K/9. It seems unlikely he'll return to MLB as he'll be 32 next season. He last pitched in MLB for the Padres in 2015.

Mateo was granted his release from the Padres on Thursday as he intends to pitch in the Japanese Central League in 2016.

EDGE Analysis

Mateo made 51 total appearances in 2015 with the Padres and their Triple-A affiliate in El Paso, most notably working a 4.00 ERA with 33 strikeouts in 27.0 innings in the big leagues. With his release, the padres were able to add Ryan Buchter to the 40-man roster.

Mateo was activated from the DL on Tuesday.

EDGE Analysis

Mateo had been on the DL since early August with a neck strain, and he recently completed a three-game rehab assignment at Triple-A El Paso. He'll rejoin the Padres and provide bullpen depth down the stretch.

Mateo's contract was purchased from Triple-A El Paso on Wednesday, Padres announcer Bob Scanlan reports. Mateo has converted nine of 12 save opportunities for Triple-A El Paso, and owns a 1.86 ERA, 0.93 WHIP and 39:10 K:BB ratio through 29 innings. He'll provide bullpen depth for San Diego at the Major League level.

Mateo has been placed on the 7-day DL at Triple-A El Paso with a strained neck muscle, Jeff Sanders of the San Diego Union-Tribune reports. Mateo, a non-roster invitee to spring training, has put together a strong start at Triple-A, posting a 2.49 ERA with an 11.2 K/9 in 17 appearances (21.2 innings).

Mateo has been reassigned to Minor League camp, MLB.com's Corey Brock reports. Mateo was a non-roster invitee to camp this spring. Over 10 innings of work this spring, Mateo posted a 5.40 ERA and allowed 15 hits. The 30-year-old reliever will head to Minor League camp along with Ramiro Pena and Jason Lane.

Marcos Mateo has been returned to the Cubs. The Diamondbacks selected Mateo in December's Rule 5 Draft but couldn't find a use for him this spring in camp. The 29-year-old missed the majority of the 2013 season while recovering from Tommy John surgery. He owns a 5.04 ERA in 44 2/3 career major league frames.

Diamondbacks selected RHP Marcos Mateo from the Cubs in the 2013 Rule 5 draft. Mateo should have no issues sticking in the big leagues next year. He has previous MLB experience -- collecting a 5.04 ERA over 44 2/3 innings between 2010-'11 with the Cubs -- and a big arm. The 29-year-old missed all of 2012 and most of 2013 while recovering from Tommy John surgery. Mateo, an import from the Dominican Republic, deals a high-90s fastball and a high-octane slider that sits in the upper-80s.

Cubs sent RHP Marcos Mateo outright to Triple-A Iowa. Mateo didn't throw a pitch this season and required Tommy John surgery in June. The 28-year-old right-hander will likely be sidelined until around mid-season next year.

Marcos Mateo underwent Tommy John surgery on his right elbow Friday. He's been on the DL all year with elbow issues, and the Cubs finally decided that he wasn't going to get better without going under the knife. Mateo will now be sidelined well into the 2013 season.
