The Last 300 game winner?

Tonight Randy Johnson goes for win #300 against the worst team in baseball, The Washington Nationals. Lets hope he gets it done and becomes the 24th and most likely last 300 game winner in baseball history. He is a mortal lock for the Hall of Fame with 5 Cy Young's and 2 no-hitters. He is also second on the all-time strikeout list with 4,843 so this win won't put him over the top. The question is, will there be a 25th member of the 300 win club? I say no. This is it people. The last one will be The Big Unit. Cherish it and understand its significance. With today's constant watching of pitch counts and innings limits, pitchers don't stay in the game long enough to get high win totals. Who do you think will be the next 300 game winner? I say no one. Here are the active win leaders and their ages:

250 - Jamie Moyer (46)
220 - Andy Pettite (37)
214 - Pedro Martinez (37)
210 - John Smoltz (42)
184 - Tim Wakefield (42)
153 - Bartolo Colon (36)
151 - Livan Hernandez (34)

So that exercise doesn't bring us any closer to a 300 game winner. Let's look at the top pitchers in the game:

140 - Roy Halladay (32)
122 - C.C. Sabathia (28)
116 - Johan Santana (30)
99 - Carlos Zambrano (28)
94 - Josh Beckett (28)

Not one pitcher under 25 has 54 career wins. Its looking like Randy Johnson is the last one. Let me know who you think will be next.
