Greg Maddux is all done.
The four-time Cy Young winner will announce his retirement Monday at the baseball winter meetings in Las Vegas.
Maddux turns 43 in April. He is eighth on the career wins list with 355, and went 8-13 last season with the San Diego Padres and Los Angeles Dodgers.
The announcement about his retirement came Friday from the office of his agent, Scott Boras.
