Those around Zack Greinke are confident that the free agent will soon become the highest-paid right-hander in baseball history.

His camp believes it's even possible that he could receive more than Cole Hamels, a left-hander, did from Philadelphia earlier this year. Hamels agreed to a six-year, $144 million extension.

CC Sabathia received the largest contract ever for a pitcher when he signed a seven-year, $161 million deal with the Yankees in 2008.
