Red Sox change bullpen again, designate reliever Seth Martinez for assignment

The Boston Red Sox have made another change to their bullpen ahead of a game against the Toronto Blue Jays on August 12. The team promoted left-handed reliever Alec Gamboa from Triple-A Worcester and designated righty Seth Martinez for assignment after his major league debut. Martinez pitched one inning, giving up a run in a 5-3 loss, while Gamboa brings a strong 2.08 ERA from previous outings this season. These moves come as the Red Sox manage an overworked bullpen and seek to maintain competitive depth. They currently have three open spots on the 40-man roster and nine players on the injured list.
