Interesting trivia fact; who is the only player in baseball history to appear in the World Series against the team that traded him that same year?   If you guessed Bengie Molina because his name is in the title, you are correct.

The Giants had Molina as a catcher from 2007 until they discovered rookie Buster Posey was an offensive force and should be playing every day, so Molina was traded to the Texas Rangers, where he helped them get to the World Series as well.   That was a good move because Posey is much better on offense and much younger but Molina was a valuable guy to San Francisco in developing their young pitchers to where they are today.

So valuable, he will even get a World Series ring if his current team loses, for his contributions to San Francisco during the first half of the season - heck, they might even vote him a share of the prize money even though he is going to use his knowledge of the Giants to do everything he can to beat them.
 
It shouldn't be any other way.

If you have been following the math since our Science Of Baseball Playoffs: Giants To Win LDS, But Don't Bet The House article, you know Bayesian statistical analysis has been pretty accurate so what do you think of the recent math that says the Rangers have a 65 % chance of winning the World Series?    On paper, the Giants were inferior to the Phillies in baserunning, hitting and fielding also.   That's why they have to play the games, as the saying goes.
