Rangers manager Ron Washington said Wednesday morning that he plans to use Joe Nathan only in save situations moving forward. Nathan closed out Tuesday's win over the Red Sox, but Washington said he would have used Alexi Ogando if the Rangers had a four-run lead. "I changed my thinking," said Washington. "If we happen to get a bigger lead, with the workload Joe has had, I'm going to try and stay away from him. I'm going to try to save every bullet we can for him for as long as we hope we will be going." Nathan is feeling much better after receiving a cortisone shot in his shoulder over the weekend, but the Rangers are going to monitor his workload the rest of the way.
