Tolleson allowed a run on a walk and no hits but still picked up the save Tuesday against the Astros, his fourth of the season.

EDGE Analysis

Tolleson walked Colby Rasmus, who stole second and later scored on a groundout. Tolleson's ERA is ugly at 10.80, but five of the six runs he allowed came in the same outing, a five-run disaster on April 6. This is the first run he has allowed since, a meaningless manufactured run in a game where his Rangers had a three-run league. Tolleson has four strikeouts against just one walk thus far.
