The Pirates announced Sunday that Bolton will be included as one of 19 players on the team's taxi squad for the 2020 season, Adam Berry of MLB.com reports.

Bolton's inclusion on the taxi squad and the Pirates' 60-man roster pool will make him eligible to see big-league action in 2020, but his lack of high-level minor-league experience makes it unlikely he'll be much of a factor for Pittsburgh. He finished the 2019 campaign with Double-A Altoona, posting a 5.85 ERA and 1.33 WHIP over nine starts with the affiliate.
