Grinder Ball Rule #45

The White Sox and Chicago White Sox Charities announced a special initiative, Grinder Ball Rule #45, inviting fans to show support alongside 2005 World Series Champion Bobby Jenks in his fight against cancer, while also directing the proceeds to one of his favorite local charities, Ronald McDonald House Charities of Chicagoland & Northwest Indiana (RMHC-CNI).

The Jenks-inspired T-Shirt features a new addition to the memorable White Sox era of team rules, “Grinder Ball Rule #45: Fight like it’s the bottom of the 9th.” The T-Shirts are on-sale now for $30. Fans also have the option to purchase a T-Shirt with an additional donation to RMHC-CNI for $45 – a nod to Jenks' White Sox number.

Proceeds benefit RMHC-CNI and its mission to provide essential services that remove barriers, strengthen families, and promote healing when children need healthcare. A cause close to the heart for the two-time All-Star, fan-favorite pitcher and father of six throughout his big-league career, the funds raised will provide critical housing and support services for families with children undergoing treatment for cancer and other serious illnesses and injuries.

Shirt Details

Fans can purchase a T-Shirt online or at the Charities Corner in Section 154 at Rate Field (while supplies last).
