Ryan Rolison did not make it to the big leagues this season, but it’s a safe bet the ex-Ole Miss star will get the call in 2021. The 6-foot-2 left-hander, a 2018 first-round pick and Colorado’s No. 2-rated prospect, was in the Rockies’ alternate camp during the 2020 season. In a recent milb.com assessment of the Rockies’ minor league system, Rolison was pegged as “the next big thing.” “So he took steps in the right direction toward a major league career here at some point over the next year-ish,” Colorado assistant GM Zach Wilson said in the story. “When that happens, I don’t know, but he’s got himself closer to that over the last year.” Rolison, projected as a big league starter, throws four pitches and has demonstrated good command in pro ball: 132 strikeouts and 40 walks in 131 innings. He is 8-8 with a 4.40 ERA after finishing the 2019 season in the high-A California League. The Tennessee native was 16-7, 3.50 during two standout years in Oxford. Rolison will likely go to spring training to compete for a spot in a rotation that needs help after Antonio Senzatela, German Marquez and Kyle Freeland. … Three Magnolia State products made their MLB debut in 2020: Mississippi State alum Brent Rooker, ex-Ocean Springs High star Garrett Crochet and Petal High’s Demarcus Evans. P.S. Washington has re-signed Ole Miss product Aaron Barrett to a minor league contract with an invite to spring training. Barrett, who has a career 4.01 ERA, pitched in two games this season.
