Another uniform change made this year for the 2010 Giants is that they're wearing orange tops on home Friday games. The uni style and letter font remain the same as the standard uni, but the color is orange. I'm not used to this yet, and the uni's look a bit bold as can be seen by this Giants TV commercial. The Giants wore orange tops as part of a rotating uni (along with white and black tops) back in the '77-'82 time span.
Back in the early 2000's, the Giants wore black jerseys on Friday, both at home and on the road, but these were done away with because they weren't the traditional uni's. Bonds hit his 71st and record breaking home run in a black top. Last night's game between the Giants and Red Sox just didn't look like the Giants vs. Red Sox. The Giants wore their orange, while the Sox wore their blue tops and gray pants.
For several years now, the Giants have had Orange Friday, but it has been the fans who wore orange to the games, including some rad 70's style orange afros here and there. Now the Giants themselves have joined their own promo. The jury is still out.
