When has this ever happened? By my count, (whatever that’s worth) we have eleven potential aces and four of the best pitchers in baseball heading the four different teams.
Texas Rangers
1. Cliff Lee

-Twenty-one strikeouts without a single walk in Rookie ball is impressive much less the playoffs.
2. Christopher John Wilson

-Now he may not be the most obvious ace but out of his thirty three 2010 starts,  TWELVE were of seven innings or more and two or fewer runs allowed, EIGHTEEN were of six innings and two runs or less.
 
New York Yankees
1. Carsten Charles Sabathia- I watched this guy throw what should have been a no-hitter two years ago in Pittsburgh.

As fast as he throws, is how he throws balls that move in every direction that sets him apart.
2. Andy Pettitte

 -For a good part of the year, this was the best pitcher on the best team in the Majors.

Philadelphia Phillies
1. Roy Halladay

-One Postseason start, One postseason no-hitter. It is scary to think what would have happened had he been with the Phillies for the last five years. His sinker, cutter scissor effect rules supreme.
2. Roy Oswalt

-Is one of the most accurate fastballs in the game supported with an absolutely hittable curve (opponents are hitting just .125 off of it) makes him an ace wherever he is if not the number one pitcher.
3. Cole Hamels-Remember, he was the star of the playoffs just two years ago

and with the same nasty change and a rejuvenated fastball he is ready to regain that spotlight.

San Francisco Giants
1. Tim Lincecum- Scouts were impressed with the fact a 5’11″ kid could hit 100 mph.

Lincecum showed a curve that was even better. The MLB hitters couldn’t hit him, he then added a change up that could dive to either side of the plate. He won a Cy Young in his first full year in the MLB.

Everyone thought he couldn’t get better, he added a slider and won his second Cy Young.
2. Matt Cain- Is something like 48-0 in games where he is given four runs or more of run support. Of course, the Giant’s offense is not know for that.

3. Jonathan Snachez- Like Wilson, he won’t pitch a shutout every game but who could forget he pitched a No-Hitter last year

and could any day with an amazing slider.
4. Madison Bumgarner 

-He is the reason I pick the Giants for the World Series this year. He had some difficulty in adjusting to the Majors but in his last seven starts he has an ERA of 1.78. If he stays healthy, I predict another Matt Cain waiting in the wings.

Well, I just love this because I prefer pitchers above hitters by a sizable margin. However, this is just my opinion. If anybody has started reading, first thank you, but secondly give your opinion of who is an ace or not and why.

P. S. just to preview I will most likely be going to Yankee Stadium for Game 4 of the ALCS
