Robinson Cano was up to bat with two outs and two aboard in the fifth, when the lights went blank.
Tropicana Field did not go dark, but the dimness created prompted Ed Rapuano's umpiring crew to clear the field while they awaited the bank of lights to re-boot to full strength.
According to the information the Rays received from Progress Energy, lightning struck a bank line that goes to a substation that feeds Tropicana Field.
Progress Energy said the strike affected the service of approximately 400 customers.
Prior to resuming play, Rays starter Alex Cobb was afforded enough pitches to again get loose. Cano grounded out on the first pitch following the delay to end the inning.
