Pittsburgh optioned Dotel to Triple-A Indianapolis on Wednesday.
Dotel made five appearances with the big-league club after being activated from the injured list July 18. In 14 games in the majors this year, the 23-year-old has a 5.06 ERA, 1.43 WHIP and 29:11 K:BB through 26.2 innings. Dotel is being sent to Triple-A in order to make room for Evan Sisk's (elbow) return from the injured list.
