The Braves are pursuing multiple options in center field, but B.J. Upton has emerged as their top choice.

Frank Wren said the Braves are still in on the biggest free agent names out there, including Michael Bourn, Josh Hamilton and Angel Pagan, but they are making a strong push for Upton.

"We like him," Wren said. "But this time of year you've got a lot of lines in the water. You're not sure which fish you're going to catch. So you have to make sure that you have enough lines out there that you catch a fish. And we're very much in that mode. We're checking. We're involved on just about everything, every center fielder that we like."
