PHILADELPHIA -- Ruben Amaro Jr. said Friday morning he will continue to look for ways to improve the Phillies' roster, but with pitchers and catchers holding their first workout at Carpenter Complex in six days, any significant additions seem unlikely.
"It's more likely we'll go in with what we've got," Amaro said.
The Phils have been talking with free-agent right-hander A.J. Burnett, but the Pirates and Orioles also are top suitors.
But Philadelphia will be one of the teams watching former closer Ryan Madson throw Friday in Arizona. Madson has not pitched since 2011 because of Tommy John surgery and complications following the surgery, but when he has been healthy, he has been one of the top relievers in baseball.
"There are several guys in that boat," Amaro said. "We'll have our eyes on these guys who are working on coming back from an injury or surgery."
It is unclear if Madson is looking for a guaranteed Major League contract, and if so, if that would scare away the Phillies.
The Phils also have been looking for a backup center fielder. Currently, John Mayberry Jr. and Tony Gwynn Jr. are the two top candidates for that job.
"There aren't a chock full of opportunities," Amaro said. "It's a possibility, but as I said, we'll probably go with what we've got and see what happens over the course of the spring."
