Triolo was optioned to Triple-A Indianapolis by the Pirates on Tuesday.
Triolo was 0-for-18 with four walks through 11 games this spring in Grapefruit League play, but he at least proved that the hyperextended left knee which plagued him down the stretch last year is no longer an issue. The 25-year-old might be able to climb to the MLB level at some point in 2023.
