Today, Jackie Robinson Day is in Major League Baseball, an annual celebration of the anniversary when Jackie Robinson broke the color barrier when he debuted on April 15, 1947, with the Brooklyn Dodgers.
Since the 2009 season, every player, coach and trainer in the entire league wears # 42 Robinson jersey with no name on the back of the jersey on April 15 (or on April 16 when his squad is not scheduled). Number 42 retired nationwide on April 15, 1997, the 50th anniversary of its debut. To this day Robinson is the only player who has received this honor in Major League Baseball.
As in 2018, all players will wear a special # 42 patch on the jersey sleeves and the right side of the caps. The patch contains 42 Dodgers-style fonts, on a cream-colored circle bordered with a blue diamond in gold. Two crossed bats behind the diamond.
Players are also given the opportunity to wear special socks for the day. The socks are similar to those from 2018, mostly black and gray with the Jackie Robinson Day logo on some thin blue and white stripes. The Jackie Robinson Day logo was repainted on the socks in 2019 and topped with an additional gray stripe:
The Los Angeles Dodgers, the franchise Robinson has spent his entire career with, will go one step further this year by wearing the white uniforms of the 1947 Brooklyn Dodgers.
While the uniform is largely similar to today's Dodgers, there are some notable differences.
The first is obviously the cap showing Brooklyn's B instead of the interlocking "LA" of Los Angeles.
On the jersey, the font for the player numbers on the back of the uniform is much thicker than 1947. A comparison of the Jackie Robinson Day jerseys worn by the Dodgers in 2018 and worn tonight shows the difference:
Also seen in the photo above, and this is real attention to detail, the Dodgers back jersey today is provided with an older jersey cut at the shoulders and arms. Note the position of the seams here from the back collar and sleeves, the fallback 2019 on the right, and what the Dodgers wore on the left for Jackie Robinson Day 2018.
The "Dodgers" log on the front of the jersey is also different, but that's much less noticeable. You can see it in the space between a few letters, I can really capture it between "r" and "s".
The "LA" logo patch, usually worn on the Dodgers jersey sleeve, is missing for today's game. The number on the front of the jersey (which was not worn by the Dodgers in '47) will still be there. However, I can imagine that it always stays that way to show everyone who wears 42.
Throwing back the 1947 design is an excellent Dodgers decision. I hope they do this for all future Jackie Robinson Day games.
Finally, some players celebrate Jackie with their own additions to their uniforms, such as Miami's Curtis Granderson, who wears these studs and was born with a new Robinson 100th Birthday logo:
As mentioned above, some teams that are not present today celebrate Jackie Robinson Day on April 16th. Some will even celebrate on the 15th and the 16th of April.
Baltimore is in Boston this morning to attend the annual Patriot Day game, which also features Jackie Robinson Day. They will then fly to St. Petersburg tomorrow, where they will again carry 42, while the rays (which go out today) celebrate their celebration.
