PHOENIX (AP) The Arizona Diamondbacks traded reliever Dustin Nippert to the Texas Rangers for minor leaguer pitcher Jose Marte on Friday.

The 26-year-old Nippert was 1-1 with a 5.56 ERA for the Diamondbacks last season but struggled this spring, posting an 0-2 mark with a 14.40 ERA in eight appearances. Nippert surrendered 24 hits in 10 innings with 14 walks and eight strikeouts.

"This was the most frustrating spring I've had so far ,so hopefully I can go there and start new," Nipper said.

It was a newsworthy day for Nippert, whose wife Carrie gave birth to a daughter, Aubrey Faith, early Friday morning.

"It's a little bit overwhelming," Nippert said. "There are a lot of emotions. They traded for me so I know they wanted me."

If Nippert makes the club, he'll fill the final roster spot still up for grabs. Right-handers Wes Littleton and Robinson Tejeda had been competing for the final place in the bullpen. Littleton was scheduled to pitch for the Rangers against the Chicago White Sox on Friday in Oklahoma City.

Marte was 4-4 with a 5.23 pitching in Class A ball last season.
