Albert Pujols entered the 400-HR club Thursday night against the Washington Nationals. Pujols led off the fourth inning by pounding a Jordan Zimmermann pitch over the wall in right center. "The Machine" is now the 47th player on the all-time list, breaking a three-way tie with Al Kaline and Andres Galarraga. He is the first player in MLB history to hit at least 400 HRs in his first 10 MLB seasons. The Cardinals' slugger is also the 3rd youngest player (30 years-222 days) to reach the milestone, behind only Alex Rodriguez and Ken Griffey Jr.
