The Under Armour Yard batting gloves worn by Bobby Witt Jr. are an updated version of the most popular Under Armour batting glove. Witt Jr.’s been wearing a clean white pair at home, and a similar pair is available for the very reasonable price of $31-$32 at Baseball Express.
It remains to be seen if Bobby Witt Jr. will be one of the select few chosen by UA to remain with the brand after he establishes himself in the MLB. Most UA superstar rookies (i.e. Vladdy Jr., Tatis Jr., Trea Turner, Judge) end up in a different brand not long after their debut.
