Red Sox promote Jedixson Paez and activate Isiah Kiner-Falefa

The Boston Red Sox promoted rookie pitcher Jedixson Paez to start Tuesday’s game against the Seattle Mariners as part of a roster expansion. Paez joins the major league club after a stint with Triple-A Worcester, where he posted a 2.92 ERA across three starts. Boston also activated infielder Isiah Kiner-Falefa from the 60-day injured list following his recovery from a forearm injury. To accommodate these additions on the 40-man roster, the team placed pitcher Eduardo Rivera on the 60-day injured list with a lumbar strain and designated infielder Brett Harris for assignment. The changes come as Boston adjusts its rotation to provide rest for veteran Sonny Gray, who will start Saturday in Baltimore instead of Tuesday.
