The Blue Jays game was delayed primarily due to rain. Specifically, the start of the game was postponed because of inclement weather in the Tampa area around Steinbrenner Field. The first pitch was originally scheduled for 7:05 p.m. ET but was delayed and expected to start around 7:20-7:30 p.m. ET. Additionally, there was a subsequent delay during the game when the home-plate umpire, Brian O'Nora, left the game due to a stomach illness, which caused another pause as a replacement umpire took over behind the plate.
Thus, the main reasons for delay: rain at game start and an in-game delay due to an umpire illness.
