The Yankees are reportedly nearing a deal with left-hander Andy Pettitte. Entering the offseason, New York was reportedly focused on re-signing Pettitte and Rivera before addressing other areas of need.

Rivera was weighing retirement after the 2012 season, but it was cut short after he tore his ACL in May. After appearing in only nine games for the Yankees last year, the veteran was once again considering calling it a career.

However, Rivera seems to want to go out on his terms, not due to an injury. The 42-year-old remains at the top of his game, as he posted sub-2.00 ERAs from 2008-2011. In 2011 he was named to his 12^th All-Star Game and garnered Cy Young consideration after maintaining an ERA of 1.91 with 44 saves over 64 appearances.
