Bradley Bergesen makes his major league debut and first career start tonight against the White Sox. Normally, that info would have me sifting through his minor league stats and various online scouting reports to figure out what type of pitcher the Sox are facing. But I've delegated that type of work to Colin now.
Instead I decided to look at how the Sox have fared recently against pitchers making their major league debut (as a starting pitcher). The Ozzie Guillen-managed Sox have only seen 7 major league debuts, and managed just 2 wins in those 7 games (opponent's ERA: 5.89). Coincidentally, Bergesen will be the 4th Oriole in the last 6 seasons to make his debut against the Sox. Orioles (Daniel Cabrera, Jim Johnson, and Garrett Olson) comprise fully half of the debuts against the Sox.
I don't know entirely what to make of that other than Baltimore has probably had a bunch of major league debuts in the last 6 years.
Also, the last pitcher to make his major league debut as a starter against the White Sox prior to Ozzie taking the helm... Mike MacDougal. The circle of life.
