Maldonado scribbled the names of his dad, brother, family and close friends on the tie, along with "Happy Father's Day'' at the bottom.
"Just wanted to do something different for the fathers out there, family members, friends,'' Maldonado said. "Something to wear for them.''
Pittsburgh Pirates backstop Elias Diaz wore a similar tie in Sunday's game against the Marlins. He entered the Pirates' 5-4 victory against Miami as a defensive replacement in the bottom of the eighth inning.
The ties were supplied by equipment manufacturer All-Star.
Maldonado drove in two runs, one with a single during a three-run second inning and another with a double in the eighth.
