Uni Watch is back, featuring more Mets tidbits:How hard can it be to get everyone on a team to wear the same undershirt color? Plenty hard, apparently, if you're the Mets, who are supposed to wear blue sleeves when donning their blue caps and black sleeves the rest of the time. But nobody bothers to enforce those rules, so you end up with games like last Saturday, in which the team's sleeves were, depending on who you looked at, [url=http://espn-i.starwave.com/media/apphoto/NYJJ10707232251.jpeg]blue[/url], [url=http://espn.go.com/i/magazine/new/050728_looper.jpg]black[/url], or [url=http://espn-i.starwave.com/media/apphoto/NYJJ10307232124.jpeg]orange[/url] (the latter of which isn't even one of the team's authorized undershirt colors but gained unofficial currency over the past dozen years because of John Franco).(Side note: the "orange" photo, above, is definitely one of the best Pedro photos out there, so Uni Watch gets bonus points for the link. I believe Edgy posted it here somewhere last week when it was taken.)edit: Also interesting:Matt Schudel points out that the question of whether the Nationals will honor the Expos' retired numbers has been answered, in the negative: Newly acquired Mike Stanton is wearing No. 30, which the 'Spos retired last year for Tim Raines.
