Young AL East arms be dealing

26-year-old master of the changeup Shaun Marcum struck out eight A's and allowed one run in the Jays' 12-inning loss. Marcum has 16 K's in 14 innings of work.

Tampa Bay's Edwin Jackson, a 24-year-old with 5 years of big league experience, improved his record to 2-0 and his ERA to 0.64 with eight shutout innings against the Mariners.

Meanwhile, Adam Loewen is not dealing. The 24-year-old lefty went five innings, walking four and allowing four runs on six hits. Looking at the ERA's of a few of the the Orioles' starters (Cabrera 9.00, Loewen 7.45, Guthrie 5.11) I was wondering how they're 6-3. Then I looked at the ERA's of several of their relievers: 0.00, 0.00, 0.00, 0.00, 0.00, 0.00. Not bad.

Tomorrow Clay faces the Yankees.
