Romano, who has a 3.06 ERA for Triple-A Louisville this season, will be recalled to start. It will be his second big league start and first since April 16 vs. the Brewers. In that game, he struggled with command, walking four over three innings.
In Chatwood's last start at Coors Field, he allowed two runs over six quality innings against the Giants on June 18. For the season, though, in seven home starts, the right-hander has a 6.39 ERA.
