SURPRISE, Ariz. -- Reliever Tanner Scheppers threw live batting practice on Thursday without any issues and is finally over the back spasms that set him back in Rangers camp.
"It went nice," pitching coach Mike Maddux said. "He got through it, threw 30 pitches and felt good afterwards. We're in the clear and full steam ahead."
Matt Harrison also resumed his throwing by playing catch at 120 feet on Thursday morning. It was the first time Harrison has thrown since being shut down at the beginning of camp because of back and neck stiffness.
"I got it stretched out a little bit," Harrison said. "It's been feeling great. My arm definitely felt fresh. I let it go a little bit, put some oomph into it ... everything felt really good."
Harrison, who missed almost all of last season with a herniated disk in his lower back, will be brought along slowly in his throwing program and is not expected to be in the Opening Day rotation.
"Each day will determine what I do that day," Harrison said. "It just depends on how I recover from the previous day."
The two most immediate concerns on the pitching staff are right-handers Shawn Tolleson and Miles Mikolas. Tolleson has been experiencing pain his right shoulder and Mikolas has been dealing with a sore elbow. Both will be examined by Dr. Shane Seroyer, the assistant team physician, this weekend.
Both are experienced pitchers with some success at the Major League level. Tolleson was 3-1 with a 4.30 ERA in 40 games with the Dodgers in 2012 while Mikolas was 2-1 with a 3.62 ERA in 25 games with the Padres in 2012. Tolleson missed most of last season with a herniated disk in his lower back and was claimed on waivers from the Dodgers. Mikolas was at Triple-A Tucson last season, recording 26 saves. He was acquired from the Pirates for first baseman Chris McGuiness.
Seahawks' Wilson won't play in Cactus League games
SURPRISE, Ariz. - Seahawks quarterback Russell Wilson is coming to Rangers camp but is not going to play in a Cactus League game.
"This guy is a Super Bowl champ," Rangers manager Ron Washington said. "They don't want him to come down here and get hurt. The guy hasn't seen a pitch. I'm not running him up there. It ain't going to happen."
Wilson will be in uniform on Monday when the Rangers play the Indians in Surprise. The Rangers took Wilson in the Minor League phase of the Rule 5 Draft during the Winter Meetings from the Rockies organization. He was a fourth-round pick by the Rockies in the 2010 First-Year Player Draft and played two seasons at the Class A level in 2010-11 before devoting himself full-time to football.
"We're just going to bring him in here, let him get acclimated, let him speak to the guys and let him enjoy his day at the ballpark," Washington said. "Our intention is to bring him in here and try and see if there is anything he can say that can help anybody wearing a baseball uniform. The guy is a winner, he has tremendous character and attitude and he is committed to what he does. That's what we're about. We just want him to feel comfortable."
One player who is looking forward to meeting Wilson is infielder Brent Lillibridge, who is in camp on a Minor League contract. Lillibridge is from the Seattle area, played baseball at the University of Washington and is a big Seahawks fan.
"It was probably the most boring Super Bowl of all-time but for us Hawks fans it was unbelievable," Lillibridge said. "I know he's going to be hounded and it's kind of a unique situation, what he's doing, especially a Super Bowl champ coming here and strapping it on as a baseball player for a little bit. It's cool he has the time to do it and I'm looking forward to at least shaking hands and hopefully having one of my jerseys signed. Looking forward to shaking the champ's hand."
• Alex Rios is expected to be in the Rangers lineup in the next couple of days after being sidelined with a sore big toe on his left foot.
• Former outfielder Rusty Greer and infielder Mark McLemore are in camp as special instructors. Former pitcher Jose Guzman and first baseman Pete O'Brien are due Monday.
• The Rangers starters for the next three days are Alexi Ogando on Friday against the Royals, Martin Perez against the Athletics on Saturday and Robbie Ross against the White Sox on Sunday.
