Lefthander Cliff Lee's arrival from Cleveland before the July trade deadline served as a concrete declaration that the Phillies had changed - that they would not sit idly and hope for the best, that they would not be content with the memories of one glorious season. They needed to get better, and that's exactly what they did, adding the 2008 American League Cy Young Award winner at the trade deadline for a modest package of prospects.

Lee pitched in just 17 games for the Phillies, but played a major role as the franchise made its first back-to-back trips to the World Series. After going 7-4 with a 3.39 ERA in 12 regular-season starts, Lee turned in one of the most dominant pitching performances in postseason history, going 4-0 with a 1.56 ERA.

Of the Phillies' nine victories in the postseason, Lee started five. He averaged more than eight innings per start. And while he left town just as quickly as he arrived, dispatched to Seattle to make room for another top-of-the-line ace, there is no question that he left his mark.

It is impossible to tell how history will judge the Phillies career of Clifton Phifer Lee, but one thing is for sure: It will be impossible to forget.
