Santiago was used in relief in Sunday's extra-inning game and gave up two runs and two home runs over one inning. He took the loss and fell to 4-4.
Santiago was pressed into duty after the Twins had used all their relievers in a 15-inning game. It was Santiago's throw day as he'd thrown a bullpen session earlier in the day, but it's not clear if the timetable for his next start will be altered.
