The Rockies signed reliever Luis Ayala and assigned him to Triple A, according to the transactions page for the Pacific Coast League. The right-hander has not pitched in the majors this year, though he did pitch 1.2 scoreless innings for Colorado Springs over the weekend.
Ayala, 32, last appeared in the majors last year when he posted a 5.63 ERA with 6.3 K/9 and 3.2 BB/9 for the Twins and Marlins. He posted similar numbers at Triple A in the Dodgers and D'Backs organizations this summer, before signing in Colorado. The Rockies continue to look for relievers, according to Jon Heyman of SI.com.
