[UPDATE] BJ Upton sent us a note after seeing this post…
@RaysIndex I never expected my uniform choice to be broken down lol but as an FYI I will be wearing pants up and stirrups the rest of season

[EARLIER] It is no secret that we love the Rays’ stirrups that are typically worn by a few players on Sundays at home with the sky blue jersey.
But we have noticed something odd about BJ Upton this season. He occasionally wears the high socks with other jerseys, and can’t seem to make up his mind whether he wants to wear long (“pajama”) pants, short pants with navy sanitary socks (“sanis”), or short pants with stirrups.
Considering the Rays have four different jerseys (white, grey, navy, sky blue) that gives Upton 12 different uniform possibilities. And so far this season he has used eight of those, with the only true pattern being that Upton always wears stirrups with the sky blue jersey (click on image for a larger version; numbers represent number of games with that combination)…
Considering players often choose a pant style based on a comfort level, we decided to see if Upton performs differently with or without the long pants (ISO is Isolated Power, the number of extra bases per at bat)…
It is not a lot of at bats for either appearance, but a trend is emerging. Upton appears to be a better hitter when he is wearing high-cuffed pants. There is also little difference between wearing just the navy blue socks or the stirrups.
We should note that there appears to be a correlation here, but that doesn’t necessarily mean causation. Upton has only once worn the pajama pants during a day-game, with 21 of the 22 coming during night games. On the other hand, nine of the 14 times that he has worn high-cuffed pants with the navy sanis or stirrups have been during day-games. So this could just be a day/night split.
But since BJ can’t get the sun to shine at night, it wouldn’t hurt to at least try the high socks/stirrups at night more often and see how it goes.
Besides, it just looks better.
