Baseball fans noticed all MLB players were wearing blue decals and equipment today and wanted to know why.

Today (June 19) is Father’s Day in the US and, across MLB, teams and players are celebrating the occasion. A number of players have donned blue wristbands and blue decals as well as other apparel in honor of the holiday.

All MLB teams wearing grey-and-blue caps

For Father’s Day 2022, all MLB Teams are wearing special grey-and-blue caps. The caps are similar to the design used for Mother’s Day, and are graphite grey with a blue crest of each club’s logo on the front. The under-visor is also tie-dye powder blue.

Why are MLB teams and players wearing blue on Father’s Day?

The caps have been in circulation for the past three seasons and are part of a wider collective by the MLB on Father’s Day.

MLB and all 30 clubs continue their campaign to champion “Keep Dad In The Game” on Father’s Day, with specialty caps and other apparel worn during games. It is done to raise awareness of prostate cancer as well as supporting Prostate Cancer Foundation and Stand Up To Cancer in their attempts to fight the disease.

According to the Prostate Cancer Foundation (PCF): “Blue is the official color for prostate cancer awareness and MLB players, managers, coaches and on-field personnel will lend their support in solidarity by wearing New Era specially designed caps featuring blue Club logos.”

A matching pair of Stance socks is also available for every player and on-field personnel may also don blue wristbands and blue decals on Nike jerseys.

Last year, players wore light-blue compression sleeves, batting gloves, wrist/elbow/leg guards and catcher’s equipment. Per an MLB press release: “Players and all on-field personnel have worn blue ribbons and sported blue wristbands on Father’s Day since MLB first partnered with the Prostate Cancer Foundation in 1996.”

All donated money will go to supporting cancer research

As they have done every year for Father’s Day, MLB will again donate 100 per cent of royalties earned on Father’s Day cap sales to the Prostate Cancer Foundation and Stand Up To Cancer.

MLB and the PCF are also uniting for the 26th Annual Home Run Challenge & Tour, which invites baseball fans to “Keep Dad In The Game” and support cancer research by pledging a donation for every home run hit on Father’s Day at

Every dollar raised through the Home Run Challenge will be granted to PCF to fund critical research to defeat prostate cancer and improve early detection methods.
