The uncharacteristic career of Craig Biggio basically breaks down like this: four years as a catcher, 14 as a second baseman, and two as an outfielder. He was an All-Star as both a catcher and second baseman. As happens with middle infielders, Biggio hit the wall at age 34, posting three mediocre seasons before he was asked to play center field by the Astros. He wasn’t a particularly great outfielder, but he played every day and continued to churn out doubles and score runs.
How much should post-season success or lack of, affect a player’s ranking? The answer: it depends.
In Biggio’s case, he played in 40 post-season games, or 1/4 of a full season. His abysmal performance (.618 OPS) surely had something to do with Houston’s playoff failures. When he finally broke out, hitting .400 against Atlanta in the 2004 NLDS, the Astros finally defeated their playoff nemesis. Overall, the Astros were 15-25 in the postseason during the Biggio/Jeff Bagwell era, losing six of nine series.
