"We talk about it all the time -- being patient, using guys differently. Our options are the Minors or other teams."
When a team has a bullpen ERA of 7.09 and the wreckage has touched just about anyone who comes out of the bullpen, the front office will go through a myriad of options.
If the Chicago Cubs can put Carlos Zambrano in the bullpen, then just about anything is viable.
"On a list of 100 thoughts, it's not high on that list," Byrnes said of moving one of his starters, say the hard-throwing Edwin Jackson and his 7.32 ERA.
"Everything gets talked about," Byrnes said. "Some things you control, some things you don't. We've lost four in a row [entering Tuesday action against the Dodgers], but we should have been in a better spot four days ago. We let some get away from us."
Byrnes also indicated that one of the options in the Minors -- left-hander Clay Zavada -- might not be available much longer. Zavada has pitched three innings in five games for Triple-A Reno with an ERA of 30.00.
"We are dealing with some issues medically," Byrnes said. "We are trying to find out what is going on. We have a decent idea, but we are going to get a second opinion."
Zavada was solid in 2009 for the bullpen when he went 3-3 with a 3.35 ERA in 49 games and 51 innings, but he didn't make the team of Spring Training.
Carlos Rosa, who was recently acquired from Kansas City on May 1, is a possible option. He is 2-1 with a 3.65 ERA in 12 1/3 innings since coming to the organization.
"We want to get him situated with our organization and evaluate him against our own," Byrnes said. "There is no doubt. He has a little bit of big league experience and he has a good arm."
