The season has been a mixed bag for Jackie Bradley Jr. but the right-hander was 1-for-1 with a three-run home run in a 7-3 win over the Mariners. Bradley was not a starter, coming in for Christian Arroyo in the top of the seventh inning and making his major-league debut. His next at-bat came in the bottom of the eighth, and the home run was his first of the season. The Boston Red Sox have also been hit by a slump, with Bradley’s batting average tumbling from 14 home runs per season to a mere .386.
