Wolf was assigned to minor league camp Tuesday, the Fort Worth Star Telegram's Stefan Stevenson reports. He will offer organizational bullpen depth this season, and should start the year at Triple-A.

Wolf signed a minor league contract with the Rangers that includes an invite to spring training, the Dallas Morning News reports. After one season pitching for the SK Wyverns of the Korea Baseball Organization, Wolf will return to the States, with an opportunity to compete for a spot in the Rangers' bullpen as a non-roster invitee. The right-hander posted a 4.85 ERA over 85.1 innings last season, but that was close to 100 points below the league average in the KBO (5.83 ERA), which introduced a livelier baseball in 2014.

Charlie Wilmoth of MLB Trade Rumors reports that Ross Wolf has exercised an out clause in his contract and will accept a deal to join the SK Wyverns in the Korean Baseball Organization. The 31-year-old right-hander registered a 4.15 ERA, 1.53 WHIP and 21/15 K/BB ratio in 47 2/3 innings for the Rangers in 2013. Rather than attempting to compete for a bullpen spot in spring training, Wolf has opted for a guaranteed job with the Wyverns.

Rangers signed RHP Ross Wolf to a minor league contract. Wolf was designated off the 40-man roster after the season and cleared waivers. Instead of seeking employment elsewhere, he accepted a minor league pact with an invite to spring training. The 31-year-old will compete for a bullpen spot in spring training.

The Rangers will call up right-hander Ross Wolf and outfielders Engel Beltre and Joey Butler on Tuesday. The trio will join the Rangers now that the season has concluded for Triple-A Round Rock. All of them have have had stints with the big club this season.

Rangers optioned RHP Ross Wolf to Triple-A Round Rock. Wolf threw 49 pitches over two innings during his last appearance on Wednesday, so the Rangers want a fresh arm for their bullpen. The 30-year-old has a 4.14 ERA and 21/14 K/BB ratio over 45 2/3 innings this season.

Ross Wolf was torched for seven runs in two-plus innings by the Orioles on Saturday. Nothing much went right for Wolf tonight; he gave up four hits in the first, two in the second and three in the third before being pulled. He pitched well in his two previous spot starts, but this one was bad enough to perhaps get him sent back to the pen.

Ross Wolf will remain in the Rangers' rotation after the All-Star break for at least one start. Wolf earned the opportunity with six quality innings in a spot start on Thursday. He's taking the rotation spot of Justin Grimm, who has been demoted to the bullpen. Wolf can be ignored in fantasy leagues.

Ross Wolf gave the Rangers a quality start Thursday, allowing two runs and three hits over six innings against the Orioles. It wasn't enough in a game in which the Rangers were held to one run, but Wolf did his job in his spot start, just as he did in his first back on June 8. He might get more chances after the break.

Ross Wolf will start for the Rangers on Thursday in Baltimore. Neil Ramirez was also under consideration to fill in for Yu Darvish, but the Rangers will give the nod to the guy that's already pitched well at the big league level this season. Wolf boasts a 1.95 ERA over 27 2/3 frames, but he's not an enticing fantasy play.
