Buchanan said he has been working on refining his curveball this offseason, the Philadelphia Inquirer reports. "It started coming along there toward the end [of last season]. But it's definitely something that has a lot of work still to go," Buchanan said. "It's definitely something I'm working on. It's getting better, which is all I can ask for."

Analysis:

Buchanan is looking for another pitch to help put hitters away. Last season, batters hit .321 when down 0-2 in the count against him. Buchanan will compete for a rotation spot with the Phillies this spring.
