Two days shy of his 30th birthday, the 2010 and 2011 America East Pitcher of the Year winner appeared in an MLB game for the first time in 13 months. Tropeano pitched four scoreless innings against the Chicago White Sox in his season debut.

Excluding the press reporters and scouts sitting behind home plate, the Orioles played what would become a 8-2 victory against the White Sox in front of empty stadium seats.
