Via SoSH, I discovered Emmingu at Fenway, another Sox blog, but one with an artistic bent - check out the drawings of Tek and Schilling.
Of course, if you want an old-fashioned throwback to pre-blog days, here’s a regular fan site, The Ballplayer Next Door, dedicated to good ol’ Billy Mueller. Seems to have started from his Giants days (it’s hosted on orange-black.net), but hey, sometimes, you root for the players, not just the laundry. Or the players that once wore the laundry. Or something like that.
Other fan sites: Totally Excellent Katcher. No prizes for guessing whom it’s dedicated to.
