Pirates signed RHP Ron Chiavacci to a minor league contract and invited him to spring training.
Chiavacci, 27, sort of resembled a prospect when he struck out 161 batters in 25 starts for Montreal’s Double-A affiliate in 2001, but he’s always had poor command. He had a 5.11 ERA in eight starts and 17 relief appearances for Triple-A Edmonton last season. There’s little chance that he’ll ever help a major league team.
