No other name comes to mind in regards to a roller coaster career than Brad Lidge. He started his career being the prodigy of Billy Wagner. In 2004, Lidge took over the closing duties for the 'Stros, and saved 29 games and struck out 153 batters in only 94-and-two-thirds innings pitched!
In 2005, Lidge saved 42 games, and was named to his first All-Star game. But, as the team made it to the postseason that year, Lidge met Mr. Pujols and the St. Louis Cardinals. In Game Five of the series, Pujols came up to face Lidge with the score 4-2 Astros in the top of the ninth. All Pujols would do is take a 0-1 pitch over the left field fence for a three-run home run, that would eventually win the game for the Cardinals. Houston would go on to win that series, only to lose the World Series to the Chicago White Sox.
But the damage had been done. That blast from Pujols planted the seeds of doubt in Lidge and the Astro fans. The shot heard round the Lone Star state, and injuries, forced Lidge to have down years in '06 and '07, and was eventually traded to the Phillies before the 2008 season. Lidge couldn't have asked for anything more. He lead the Phils to a World Series championship that year, and finished fourth in the Cy Young award voting, saving 41 consecutive games for the Phils.
Lidge seems to have found his stuff again. And though he may get slowed from nagging injuries, his future seems to be as bright as his past.
