The annual Uni Watch World Series Preview

The Fall Classic, featuring the Los Angeles Dodgers and the Boston Red Sox, begins on Tuesday night, which means it's time for the annual Uni Watch World Series Preview. While others obsess about meaningless stats like WAR, exit velocity and launch angle, we know what you really want -- 10 intriguing factoids about the World Series teams' uniforms. And here they are:

1. Old-school. If you're a fan of classic uniform styling, this year's Series should be to your liking. Both teams have kept their basic look intact for decades, the Sox don't have player names on their home jerseys, the Dodgers don't have a solid-colored alternate jersey in their wardrobe, and neither team has an alternate cap. Heck, even the two stadiums are old-school! If the Sox can stay away from their red and navy alternate jerseys, this Fall Classic should be a traditionalist's delight.

2. Déjà blue. For the third straight year, the National League team's colors include royal blue and the American League team's colors include a darker blue. In 2016, it was the Cubs (royal) against the Indians (navy); in 2017, the Dodgers (royal) and the Astros (navy); and this year it's the Dodgers (royal) and the Red Sox (navy).

This also marks the 13th consecutive World Series in which at least one team's colors include a shade of blue. The last blue-free Series was in 2005, when the Astros (who hadn't yet added navy to their color scheme) faced the White Sox.

3. October surprise. If you watched the Dodgers during the NLDS and NLCS, you may have noticed shortstop Manny Machado's undershirt showing through his jersey. The base-layer design appeared to feature a very Orioles-esque script "O," leading many fans to surmise that Machado was wearing one of his old Baltimore undershirts. That would certainly make for an interesting subplot, but he was actually wearing one of the several October-themed shirts that MLB produced for the postseason.

4. Capping it off. Red Sox pitcher David Price doesn't like wearing a squatchee -- the little button on the top of a baseball cap. He calls it the "ouch button," because he's 6-foot-5 and sometimes hits his head on the top of the dugout, so the button and the rivet that holds it in place can be annoying. For the past several years, he's had the squatchee removed from his caps, but seasoned uni-watchers were surprised to see him going squatchee-clad for his two starts in the ALCS -- which happened to be the best two postseason starts of his career. That creates an interesting situation for the World Series: Will squatchee superstition win out over "ouch button" phobia? Stay tuned. (For more on the term "squatchee," look here.)

5. Red letter number day. Many fans over the years have wondered why the Dodgers' jerseys feature those red numbers on the front, which they've been wearing since 1952. After all, red doesn't appear anywhere else on their uniforms, so why have the red numbers?

The answer to that question was uncovered a year ago by uniform designer and historian Todd Radom, who found an old article indicating that the Dodgers had actually planned to add the red numbers as a special addition for the 1951 World Series. As it turned out, the Dodgers didn't make it to the '51 Fall Classic (that was the year they were knocked out by the Giants, courtesy of Bobby Thomson's famous "Shot Heard 'Round the World"), but the red-numbered uniforms had already been ordered, so team ownership decided to use them for the 1952 season, and the numbers have been part of the Dodgers' look ever since. Additional details here.

6. Numbers game. Fans often refer to Boston's familiar number font as "the Red Sox font," but it actually has a name: McAuliffe. It was created by and named after the Tim McAuliffe sporting goods company, which supplied uniforms for many MLB teams back in the day -- and most of those teams wore the McAuliffe number font. Today the Sox are the only team to wear it on their jerseys (although the Cubs, oddly, wear it on their batting helmets). For more info on McAuliffe, look here.

7. To "B" or not to "B." The Dodgers and Red Sox have an unusual bit of shared uni-related history. Back when the Dodgers played in Brooklyn, their caps had a "B" logo -- which happened to be very similar to Boston's iconic "B" logo. There was much less standardization back in those days, so logos often changed a bit from year to year as new manufacturers and vendors took over. Still, even while accounting for some of the variations, the Dodgers and Sox definitely have some shared visual DNA. (For additional info, check out this Twitter thread.)

8. The high and the low of it. The Dodgers' pitching roster includes two players with atypical uni numbers: Hyun-Jin Ryu, who wears No. 99, and Julio Urias, who wears No. 7 -- a rare single-digit number for a pitcher. If Ryu were to be relieved by Urías -- which actually happened during Game 6 of the NLCS -- that would produce a uni number differential of 92, which would be a presumptive World Series record for one pitcher relieving another, at least until someone can demonstrate otherwise!

9. Name game. When J.D. Martinez joined the Tigers in 2014, Victor Martinez was also on the roster, so J.D. wore his full name on the back of his jersey. He kept doing that when he joined the Diamondbacks in 2017 and again when he joined the Red Sox this season, even though the D-backs and Bosox had no other Martinezes on their rosters.

10. Letter imperfect. Boston's home jersey has a gorgeous symmetry -- three letters on one side, three on the other side, and a space in between. But their road jersey has the "T" positioned in the center, with three letters on one side of it (B-O-S) and only two letters on the other side (O-N), creating a lopsided effect that makes it look like the whole jersey is leaning to one side. Once you see it, you can't un-see it. (For more on this jersey phenomenon, which afflicts several other teams, look here.)

Honorable Mention. Dodgers utility man Enrique Hernandez has his jersey sewn shut, and he and teammate Chris Taylor have both been wearing excellent stirrups. But you already knew that if you watched last year's World Series!
