Fulmer was recalled from Triple-A Toledo on Friday and will start in Friday's game against the Twins.
Fulmer will pitch in place of Shane Greene who was placed on the 15-day DL with a right middle finger blister. The 23-year-old has a mediocre 4.11 ERA through three games at Triple-A but has a tremendous 11.92 K/9 and will have a great matchup against the Twins, who rank 25th in runs scored and fourth in strikeouts on the season.
