This may or may not be correct, but I believe, that in 1972, Reggie Jackson was the first major leaguer to sport facial hair, and instead of fighting Reggie's rebelliousness, A's owner Charles Finley offered a $50 bonus to every player on the team to grow a mustache, and every player on the team took him up on it, including manager Dick Williams. That team went on to win 3 straight World Series, so I reckon Giambi could choose worse adornments.... In fact, according to the baseball library, facial hair was commonplace in the 1890's and early 20th century. John McGraw was one of many. The last player with a moustache for many years was Wally Schang of the Philadelphia Athletics in 1914. The first modern day players to wear moustaches were Dick Allen and Felipe Alou in 1970.
I think ballplayers should be required to have 'staches. Makes it seem like old time baseball all the time.
That picture is hilarious. Jeter looks a bit like Freddie Mercury.
Watching the Yankees/Royals game now, and Giambi started the game wearing his mustache, but he apparently had time to shave between innings 'cause it's gone now.
Shave those damn sideburns Mattingly!
