Nothing has changed. Aardsma was always meant to be a closer. He has been blessed with an unbelievable amount of talent. With the White Sox, he only pitched in 25 games (32.1 innings). You can't really judge a player, especially someone who is only in their second year and who has just went from the N.L. to the A.L. (to an across town team, on top of that), based on a small amount of playing time. The season before that, in his first full season, he progressed greatly as the season went on. In 2008, with the Red Sox, he was mismanaged. In 2009, with the Mariners, he was finally given the chance to pitch in the manner that best suits him, his perceived mentality and his skill set. The results of this were exactly what I always expected to see from him as a closer.
