LOS ANGELES (AP) _ Struggling rookie reliever Jose Nunez was designated for assignment Tuesday by the Los Angeles Dodgers, who purchased the contract of right-hander Giovanni Carrara from Triple-A Salt Lake.

Nunez, 22, became the only lefty in the Dodgers' bullpen after they released Jesse Orosco at the end of spring training. Nunez has a 13.50 ERA, after surrendering nine runs in 1 1-3 innings of mop-up duty during Saturday's 20-1 loss at Chicago. He allowed a home run in four of his seven appearances spanning 7 1-3 innings, and opponents are batting .389 against him.

The Dodgers selected Nunez from the New York Mets in the Rule 5 draft last year. By designating him for assignment, Los Angeles has 10 days to decide what to do with him. They were forced to keep him on the 25-man roster or offer him back to the Mets for $25,000.

If any other team claimed Nunez off waivers, they also would have to keep him on the 25-man roster or ship him back to the Mets for $25,000.

Orosco currently is back with the Dodgers organization after signing a minor league contract last month. He has pitched in four games without allowing an earned run or a walk.
