For three of the past four seasons the National League has owned Major League Baseball. But after collectively opening its wallet this past winter, the American League could see a return to dominance in 2012.

The American League bought two of the National League’s biggest stars this offseason when the Angels signed Albert Pujols and the Tigers added slugger Prince Fielder. The Halos also kept C.J. Wilson (the top pitcher on the market) in the AL West while the Yankees beefed up their starting rotation by acquiring promising young right-hander Michael Pineda (now injured) from the Mariners and signing the underrated Hiroki Kuroda (formerly of the Dodgers).

Granted, there are still plenty of quality teams in the National League. The Phillies, Giants, Brewers and Braves all have solid starting rotations and the Marlins bolstered their roster with the additions of Jose Reyes, Heath Bell and Mark Buehrle. The Reds and Diamondbacks have plenty going for themselves as well.

But all of the teams listed above have significant question marks heading into the season, which includes the defending World Series champion Cardinals. Ace Chris Carpenter, outfielder Allen Craig, and second baseman Skip Schumaker will all miss significant time this offseason and there’s added pressure for guys like Matt Holliday, Lance Berkman and David Freese to produce without No. 5 in the lineup.

When you factor in Pujols and Fielder have jumped leagues, it’s no wonder the odds currently favor AL teams like the Tigers, Yankees, Angels and Rangers when it comes to winning this year’s World Series. The American League rosters are simply more talented right now than their National League counterparts.

Now, I’m certainly not suggesting that the American League is a shoe-in to win the Fall Classic. Get into a seven-game series when pitchers reign supreme and you cannot count teams like the Phillies, Braves and Giants out of contention. If you think offense overpowers pitching when it comes to the postseason, then you haven’t been paying attention the last two years.

But as of April 1, there’s no question that the balance of power has tilted in the American League’s favor. There’s a lot of baseball to be played but it’s hard not to look up and down the Tigers’ roster and not think, “Wow, this is a potential World Series winner right here.”
