Prince Fielder connected for his first home run of the season today in what was his 54th at-bat of the season, ending yet another "home run drought" to start the season.  There's no reason to be concerned about Prince's slow start though.  Looking back at Prince's 4+ full seasons, the following trend emerges:

2006: Prince's first full season.  He wasn't exactly in a slump, as he was hitting .327 entering the game of his 54th AB, but he only had 1 HR.  He would hit his second in the game of his 54th AB.

2007: The year Prince hit 50 HR.  Coming into the game of his 54th AB, however, he was hitting .288 with only 1 HR.  Two games after the game of his 54th AB, he hit his second home run, and would his 48 more over the course of the season.

2008: Prince entered the game of his 54th AB hitting only .224 with 0 HR.  He hit a home run in his 54th AB (the exact same as today) and would finish the season with a .276 AVG and 33 more HR.

2009: Prince's best offensive season to date.  Entering the game of his 54th AB though, he was hitting a paltry .196 with only 1 HR.  In the game following the game of his 54th AB, he would hit 2 HR and finish the season with 43 more and on the cusp of batting .300. 

2010: Prince gets going by crushing his first HR of the season, again in his 54th AB.  Entering the game he was hitting .226, obviously with 0 HR.  He goes on to win NL MVP and lead the Brewers to the World Series?

*Edit* - I had originally miscounted and thought that he hit a HR in the game of his 54th AB every season.  Darn, I thought I was on to something!
