Reliever Zach Miner, who was in Detroit's rotation at the start of the season, started in Galarraga's place and lasted 4 2/3 innings, allowing five runs on seven hits with two walks and three strikeouts in an 8-2 loss. He pitched two innings on Monday.
Galarraga has been dealing with a sore throat and fever, among other symptoms, since before the Tigers arrived in town. Head athletic trainer Kevin Rand said Wednesday that Galarraga hasn't been able to hold down solid food for two days, sapping his energy level. He had been sent back to the team hotel the past two days to get his rest and keep his illness from spreading around the team.
Galarraga arrived in the Tigers' clubhouse Wednesday afternoon, but clearly didn't look well. He saw a doctor and was sent back to the hotel again.
With rookie right-hander Rick Porcello serving a five-game suspension for Tuesday's altercation with Kevin Youkilis, the Tigers have tentatively scheduled Galarraga to return to action against the Royals on Sunday, which was supposed to be Porcello's turn in the rotation.
This was the second time in three years that Miner made a spot start at Fenway Park. He was called up from Triple-A Toledo to start the first game of a day-night doubleheader in 2007 after scheduled starter Mike Maroth was scratched with food poisoning.
