Burrows was added to the Pirates' 40-man roster Tuesday, Justice delos Santos of MLB.com reports.
Burrows split time between Double-A and Triple-A in 2022, putting up a 4.01 ERA and 1.21 WHIP over 94.1 innings on the season. The 23-year-old righty struggled in Triple-A, however, so Burrows will likely need more seasoning in Indianapolis before the Pirates seriously consider bringing him to their big-league roster.
