The Pirates optioned Jones to the Florida Complex League on Saturday.
Jones' season was already over after he made his final start of the season Friday, so the Pirates will simply send him to their complex in Florida to finish the season, opening up a roster spot for Mike Burrows in the process. The 23-year-old Jones will finish his rookie campaign with a 4.14 ERA and 1.19 WHIP alongside a 132:39 K:BB across 22 starts.
