SEA@HOU: Saunders fans two over 5 1/3 solid frames

The Rangers signed left-hander Joe Saunders to a Major League contract on Wednesday.

Infielder-outfielder Alex Castellanos was designated for assignment to make room for Saunders on the big league roster.

The nine-year veteran spent last season with the Mariners, posting an 11-16 record and a 5.26 ERA in 32 starts. The Mariners declined their 2014 option on Saunders' contract after the season.

Saunders, an All-Star in 2008 with the Angels, has pitched for three teams -- the D-backs, Orioles and Mariners -- over the past two seasons. He is 89-81 with a 4.30 ERA in his career.

A report on Tuesday said that Saunders worked out for the Rangers last week in Surprise, Ariz., and the lefty told MLB Network Radio that Texas would be a "perfect fit." Saunders adds depth to a starting rotation that may not have Derek Holland and Matt Harrison at the beginning of the year because of injuries.

Adcock shut down after reporting numbness in fingers

ARI@KC: Adcock pitches five frames of one-run ball

SURPRISE, Ariz. -- Right-handed reliever Nate Adcock felt numbness in the fingers on his throwing hand during his outing Sunday, and the Rangers have shut him down until he can be examined by team physician Keith Meister this weekend.

Adcock allowed four runs in two-thirds of an inning against the White Sox on Sunday and picked up the loss in a 9-7 defeat. Adcock complained of the numbness to the team shortly after he was removed from the game, according to assistant general manager Thad Levine.

"We're just having him shut down right now," Levine said. "Meister will be back this weekend, and we'll have him be fully evaluated at that point to see if there's anything significant to those symptoms."

The 26-year-old hasn't pitched at the Major League level since 2012, when he posted a 2.34 ERA with a 1.44 WHIP in 12 appearances for the Royals. In addition to Sunday's rough outing, Adcock also allowed two runs on three hits against Kansas City on Friday. He is competing for one of Texas' final bullpen spots.

In other injury developments, manager Ron Washington is hopeful shortstop Elvis Andrus can return to the lineup on Thursday. Andrus hasn't played since Friday because of flexor tendinitis in his right arm, which the Rangers say is typical spring soreness.

Meanwhile, catcher Geovany Soto, who had surgery to have a small bone in his left foot removed, has begun hitting off a tee and taking soft toss. Mid-March remains the target return date for Soto.

Worth noting

• In his first appearance of the spring, left-hander Rafael Perez faced one batter, getting Efren Navarro to line out to shortstop Adam Rosales. Perez had been set back by about a week with a right-hamstring strain.

• Ailing right-handed relievers Miles Mikolas (elbow) and Shawn Tolleson (shoulder) each threw from 90 feet on Tuesday morning.

• Washington on newly acquired utility man Andy Parrino:

"I don't know much about him except for reports I got that he can play everywhere, and he's a gutty player. He's joined the team, so we'll see what he has to offer."
