Power numbers are up in major league baseball.

Uh oh.

What does this mean? Have players found another performance enhancing drug that is undetectable to the Bud Selig Steriod Police?

Probably not. The power surge is most likely a simple case of bad pitching, plus young, developing power hitters, plus small ballparks equaling a longball spike.

Not everyone is part of the surge. Several former boppers are hitting more like bloopers this season.

Here’s a breakdown of the winners and losers in this year’s Power Parade.

Shopping in the “this is not a steroid, honest” aisle at GNC:

-- Joe Mauer. His career high for home runs in a season is 13. The Twins’ catcher has already smacked 11 in 81 at-bats while batting a robust .444. That’s scary good. That's $30 million a year good when he becomes a free agent.

-- Mark Teixeira. The Yanks’ first baseman shattered his bat and still hit a home run in that bandbox called Yankees Stadium. No, really, it’s a bandbox. George Steinbrenner uses it to store his hat, clerical collars, or other articles of apparel.

-- Adrian Gonzalez. So much for Petco Park being a dog of a place to hit home runs. The Pads’ first baseman has 17 to lead the majors.

Stricken with Nyjer Morgan-Jason Kendall syndrome:

-- David Wright. Has hit only three home runs this season. His power usually spikes as the weather warms, so the verdict is still out on the face of the Mets.

-- David Ortiz. Tito Ortiz could probably hit more home runs this season than Big Papi. The Red Sox dropped Ortiz to sixth in the order, resisting the urge to drop him all the way down to 10th.

-- Jhonny Peralta. After leading all American League shortstops in homers last season, Peralta has just one for the Tribe in 2009. He also struggled at the Spelling Bee this weekend when he spelled johannes, a gold coin used as currency in Portugal, j-h-o-a-n-n-e-s.
