Betancourt (vertigo symptoms) threw a bullpen session Tuesday, the Associated Press reports. Betancourt, who was placed on the DL on June 8, seems to be making progress in his recovery from the condition, but is still facing an indefinite timetable for his return. He was enjoying a productive season before getting clobbered in his final few appearances prior to landing on the DL, which has inflated his ERA to 6.30 despite his tidy 20:3 K:BB ratio.
