Let's not forget the virtually unknown feat of BoBo Holloman of the 1953 St. Louis Browns. He pitched a no-hitter in his first major league star against the Philadelphia A's.

Here is the Wikipedia entry, but I remembered it from "Veeck As In Wreck", one of the absolutlely great baseball autobiographies.

"Alva Lee "Bobo" Holloman (March 7, 1925 - May 1, 1987) was an American right-handed pitcher in Major League Baseball for the St. Louis Browns in 1953. Holloman pitched in just 22 games in his lone year, with three wins against seven losses. However, he pitched a no-hitter in his first major league start against the Philadelphia Athletics on May 6, 1953 and remains the only pitcher in MLB history to ever have thown a no-hitter in his first major league start."

Clay Buchholz was drafted by the Red Sox with the pick they received in compensation for the Mets signing Pedro. Thank you.
