Do Deadline Deals = World Series Titles?

I personally believe that the Angels should do everything in their power to make a trade this season. They really are one good hitter away from being a serious contender. As it stands, their pitching staff could almost contend on it's own.

That being said, I wanted to take a look back at the past five World Series winners and what they did at the deadline to ensure winning the title.

2006 Cardinals vs Tigers 4-1
The Cardinals acquired Ronnie Belliard from Cleveland for Hector Luna and also acquired Jorge Sosa from Atlanta for minor leaguer Rich Scalamandre . Belliard hit .237 for the Cardinals and Sosa had an era of 5.28 in 19 relief appearances. Sosa didn't even pitch in the series and Belliard went 0-for-12.
Verdict - Deals were worthless.

2005 White Sox vs Astros 4-0
The Whtie Sox acquired Geoff Blum from the Padres for minor leaguer Ryan Meaux. Blum hit .200 for Chicago. Blum had one at-bat in the World Series and made it count. He hit a solo shot in the top of the 14th inning in the Sox 7-5 Game 3 win at Houston.
Verdict - Though Blum had a big hit, the White Sox would have easily taken care of the Astros without him. Deal was worthless.

2004 Red Sox vs Cardinals 4-0
As part of a four-team deal, the Red Sox received Doug Mientkiewicz from the Minnesota Twins and Orlando Cabrera from the Montreal Expos and sent Nomar Garciaparra and minor leaguer Matt Murton to the Chicago Cubs. They also received Dave Roberts from the Dodgers for minor leaguer Henri Stanley. Garciaparra had become a clubhouse distraction and the Boston defense was much improved with Cabrera and Mientkiewicz. Cabrera thrived, hitting .294 while Mientkiewicz hit just .215. Cabrera was 4-for-17 in the World Series and Mientkiewicz was 0-for-1.
Verdict - Deals were good.

2003 Marlins vs Yankees 4-2
The Marlins made no deadline deals, but did acquire Ugueth Urbina on July 11th from Texas for Adrian Gonzales, Ryan Snare and Will Smith. In 31 appearances, Urbina was 3-0 with 6 saves and a sparkling 1.41 era. In the World Series, Urbina saved two games.
Verdict - No deadline deals.

I don't feel a need to look at 2002, as everything went perfectly - Sal Fasano and Alex Ochoa were the best signings ever.

Looking at the last few years, it turns out that World Series winners are not helped by deals made at the deadline. That's not to say that deadline deals are not important. But in recent history they are no guarantee of post season success.
