Triolo went 3-for-4 with a double, two runs scored and an RBI in Saturday's 9-7 loss to the Reds.
Triolo was involved in several rallies Saturday and tallied his second three-hit game of the season. He had been serving as Pittsburgh's primary shortstop while Konnor Griffin was on the shelf for nearly a month, but with Griffin returning to action Friday, Triolo is expected to shift back to a utility infield role and see a steady drop in playing time.
