The Colorado Rockies announced on Saturday afternoon a series of pitching-focused roster moves
prior to their Independence Day fireworks game against the San Francisco Giants.Right-handed pitcher Tomoyuki Sugano (菅野 智之) has been placed on the 15-day injured list with back spasms.
Sugano, 36, was scheduled to start on Saturday night. He has been one of the Rockies’ most reliable starting pitchers this season with a 4.80 ERA in 16 starts with 48 strikeouts over 84.1 innings. Although he has been prone
to giving up home runs both during his career and with the Rockies, the damage has generally been limited to solo home runs. He has pounded the strike zone and given up very few walks.
Left-handed rookie pitcher Sean Sullivan (no. 8 PuRP) has been recalled from the Triple-A Albuquerque Isotopes to start in place of the injured Sugano.
Sullivan, 23, made his debut in June and made four starts for the Rockies before being optioned back to Triple-A Albuquerque. The deceptive lefty has an arsenal of breaking pitchers but a four-seam fastball that has averaged just 87.9 MPH against Major League hitters. He has struggled to find length in his big league outings—making it through five innings just once—and has given up a lot of contact with 16 earned runs over 16.2 innings. However, in his last start against the Miami Marlins he had appeared to have started finding his strikeout stuff. He struck out an early career-high five batters.
The Rockies have also selected the contract of right-handed reliever Jordan Romano from Triple-A Albuquerque, adding him to the 40-man roster.
Romano, 33, signed a minor league contract with the Rockies in May after he was designated for assignment by the Los Angeles Angels.
A former two-time All-Star with the Toronto Blue Jays, Romano has struggled to find his form after needing shoulder surgery in 2024. After signing with the Rockies, he spent roughly a month with the team’s pitching and performance lab at their Arizona Complex before being assigned to the Isotopes. In nine appearances and 8.2 innings with Albuquerque he has posted a 4.15 ERA with ten strikeouts and no walks.
In a corresponding roster move, right-handed reliever Seth Halvorsen has been placed on the 15-day injured list with right shoulder inflammation.
Halvorsen, 26, has spent time bouncing back and forth between the big league roster and Triple-A Albuquerque this year after recovering from an elbow injury he suffered last season. In 21 appearances with the Rockies he has posted a 4.74 ERA with 17 strikeouts. He has struggled to command his pitches, issuing 15 walks over 19 innings of work.
The Rockies’ 40-man roster is currently full. Both injured list moves are retroactive to July 1st.
