Brazil striker Luis Fabiano was overlooked once again but Alvaro Negredo gave Sevilla the lead from the penalty spot after only 13 minutes as the hosts dominated.
Racing levelled with a fizzing volley from Pablo Pinillos in the 54th and Sevilla laboured to react, prompting howls of protest from their fans when the referee blew for time.
"I'm sorry for Andres. He's a great professional and loves Sevilla. He's just anxious to see the team do well and win at home, as are all the players," coach Antonio Alvarez told Spanish radio.
Calls for Alvarez to resign surfaced again, as they did after Sevilla's surprise failure to qualify for the Champions League group stages last month, but he laughed them off.
"I have great enthusiasm to continue and have no problems at all with the president or the sports director," he added.
The King's Cup holders are fifth with eight points from four games, two points behind the leaders.
Jose Mourinho's Real saw off Espanyol 3-0 at the Bernabeu on Tuesday and climbed above Valencia on goal difference after Unai Emery's side drew 1-1 at home to Atletico Madrid on Wednesday.
