21. San Francisco Giants (Away Alternate)
The Giants used an interlocking NY on caps and jerseys during their time in New York, so it was natural that the club would use an interlocking SF when it moved across the country to San Francisco in 1958. The logo has been part of the on-field uniform every season since, only going through minor style changes along the way.
However, the interlocking SF did not appear on any of the team’s jerseys until 1983, when a black SF outlined in orange was placed on a gray jersey, replacing the orange and black tops the club used from 1978-82. The Giants wore the SF on the left breast of their road jerseys for a decade, and wore it in the 1989 World Series during that span (just the second World Series appearance for the club since the move four decades earlier), before it was replaced with “San Francisco” in 1999. While the look was sharp from the front, the bubbly number style was less than perfect.
In 2012, the style returned, and thanks to a better number style, the interlocking SF gave San Francisco one of the best away jerseys in Major League Baseball. Unfortunately, the Giants only wear it as an alternate, opting for the full city name on the front of their tops during the majority of road contests.
And, coincidentally, the Giants finally made it back to the World Series in 2012, and won the first World Championship for the franchise since moving in San Francisco. The SF alternate is still in the rotation, and the club has added two more World Series rings since.
