Petty didn't pitch in Saturday's 4-1 win over the Guardians after being expected to operate as the primary pitcher.
EDGE Analysis
The right-hander was initially listed as Cincinnati's probable starter for Saturday, but Brent Suter delivered three scoreless frames as the opener. Manager Terry Francona then elected to shift to a bullpen game rather than call upon Petty, who has surrendered 13 earned runs with a 7:8 K:BB in his first 5.1 big-league innings. It remains to be seen if Petty will receive another turn through the rotation before returning to the minors.
