Randy Johnson and Tom Glavine were baseball’s last pitchers to reach 300 wins.

Johnson accomplished the feat in 2009 with the San Francisco Giants, while Glavine achieved the milestone in 2007 with the New York Mets. Glavine returned to the Atlanta Braves, his original team, the following year and retired following a brilliant 22-year career.

Who will join them next? There are plenty of worthy candidates.

Jamie Moyer currently leads active pitchers in career wins with 267, but he’s also 47 years old. Andy Pettitte is right behind at 240, but he still hasn’t decided whether to retire or return to the New York Yankees.

So who has the best shot? You can’t measure it just on career wins alone. Otherwise 43-year-old Tim Wakefield, who has 193 wins, would have a better shot than Roy Halladay (169).

Age also has to be somewhat of a factor. Other things can’t be measured or predicted, like whether a pitcher can remain injury-free, if the divisions they’re in get even tougher or if their skills simply diminish.

These 20 have the best chance, though, to reach the 300-win mark.
