Right-hander Kelvim Escobar was activated from the 60-day disabled list before the Angels opened up a critical nine-game road trip at Boston. Escobar had been on the disabled list three times this season, including his most recent stint which involved elbow surgery on June 29. Escobar, who is 2-2 with a 3.54 ERA in seven starts this season, returns to Anaheim's staff at a crucial time.
