Rodriguez went back to his old delivery for Wednesday night's game against the White Sox and had his most powerful fastball of the season, Jason Mastrodonato of the Boston Herald reports.
Rodriguez had been using a modified delivery after rehabbing a knee injury suffered during spring training, but was experiencing diminished velocity on his fastball. Going back to his old delivery Wednesday, the left-hander's heater was sitting consistently around 95-96 mph. While he gave up two more homers Wednesday -- that's seven homers allowed in 26.2 innings -- Rodriguez struck out a season-high seven.
