As Father's Day approaches, Major League Baseball today announced details surrounding league-wide efforts to raise awareness about prostate cancer and raise funds for research to fight the disease. 
During Father's Day weekend, players and on-field personnel will wear the symbolic blue ribbon on their uniforms along with blue wristbands. Also, for the second consecutive year, players will wear specially-designed uniforms and caps to raise awareness and funds for the fight against prostate cancer. The uniforms incorporate blue into the Clubs' regular logos while the caps are highlighted by a blue shadow tech heather crown and graphite visor. Players also have options from two different pairs of blue-infused socks. MLB will again donate all royalty payments from the sales of specialty caps and jerseys to the Prostate Cancer Foundation and Stand Up To Cancer. For the first time, players and on-field personnel will wear the blue-infused attire and equipment throughout Father's Day Weekend.
Commemorative base jewels and dugout lineup cards also will be blue. In addition, the following game equipment can be used for prostate cancer awareness throughout Father's Day Weekend: blue compression sleeves, blue batting gloves, blue footwear, blue wrist/elbow/leg guards and catcher's equipment. For the first time, Father's Day games will feature a blue-stitched Rawlings baseball, the official ball of MLB, as the official game ball. 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.
This year's efforts also includes the annual Prostate Cancer Foundation "Home Run Challenge," which has given fans the chance to make a one-time monetary donation or pledge for every home run hit by their favorite MLB Clubs during the time period of Thursday, June 1st through Father's Day, Sunday, June 18th, all the while tracking where their team stacks up in a "Team vs. Team" competition. Every dollar donated through the Home Run Challenge goes to PCF to fund critical research to defeat prostate cancer. As of June 15th, more than $3 million has been pledged via the Home Run Challenge in 2017. Additionally, several Clubs, including the Minnesota Twins, Milwaukee Brewers and Seattle Mariners, have pledged a dollar amount for every home run their teams have hit during the Home Run Challenge time period. Since inception, the Home Run Challenge has raised more than $45 million for PCF, the world's leading philanthropic organization funding and accelerating prostate cancer research. 
Several MLB Clubs will host special pregame ceremonies, including ceremonial first pitches and representatives from the Prostate Cancer Foundation attending games.
On Father's Day, MLB.com, all 30 Clubs and broadcast partners will express their gratitude by sharing their favorite baseball moments of Dad on social media using #MLBDads, and fans are encouraged to do the same.
Overall, PCF has raised more than $700 million for prostate cancer research to date, which has resulted in helping bring six prostate cancer medicines to patients.  Every 20 minutes, a man in the U.S. dies from prostate cancer.  For more information about PCF, please visit PCF.org.
