Question: why are mlb players wearing the number 45 on their sleeves?
Answer: Most, such as Chicago White Sox pitcher Lucas Giolito, sported it throughout the game. The patches, which were not sewn on, fell off the jerseys of others. The Angels' Mike Trout (wearing No. 45 in honor of Tyler Skaggs) bats against the National League during the All-Star game Tuesday night in Cleveland.
