Colorado Rockies rookie left-hander Ryan Rolison will serve as the team's "opener" for Friday's series opener at Coors Field against the visiting New York Mets, according to MLB.com's Thomas Harding. Rolison has been converted to a relief role this year, but he has been used as an opener and scheduled multi-inning pitcher. Right-hander Antonio Senzatela is expected to be the bulk reliever in this game against the Mets after Rolison leaves early. The 27-year-old Rolison will be making the first start of his MLB career after appearing all seven times in relief in his rookie season this year. In 10 innings out of the 'pen, Rolison has allowed five earned runs on 10 hits (one homer) while walking six and fanning eight. Fantasy managers should avoid both Rolison and Senzatela on Friday against the first-place Mets at hitter-friendly Coors Field.

The Colorado Rockies will consider using left-hander Ryan Rolison, their top pitching prospect, as a long-relief option in their bullpen to start the 2022 season. Rolison would be making his major league debut. Chad Kuhl, who the Rockies signed on Monday, is in line for the fifth spot in the starting rotation. Rolison was the team's first-round pick back in 2018, and he struggled with a 5.27 ERA and 1.37 WHIP in 16 starts (71 2/3 frames) for the Rookie League Rockies, High-A Spokane, Double-A Hartford and Triple-A Albuquerque in 2021. The 24-year-old has a nice four-pitch mix and has the ability to fill up the strike zone with regularity. Rolison won't be a fantasy commodity in the bullpen, but he'll be worth a look later on if he eventually wins a rotation job in Colorado.
