* In 2006 the Braves signed Wayne Franklin. Remember his cup of coffee with the Yankees in 2005? George Steinbrenner ordered him banished - aka, Columbus, here I come - after he gave up a home run to Hank Blalock.
* In 1997 the Expos signed Hensley Meulens.
* Also in '97 the A's signed Todd Van Poppel, perhaps the most hyped pitcher ever.
* In 1991 the Astros signed Calvin Schiraldi. If the Red Sox brought him back to throw out the first pitch, I bet he'd still get booed.
* In 1981 the Astros signed David Clyde. There's great details about his debut at age 18 in this highly entertaining book.
