Ryan Perry Rolison (born July 11, 1997) is an American professional baseball pitcher in the Colorado Rockies organization.

[1] As a senior, he was 9-0 in nine starts, striking out 108 in 58 innings while allowing only three runs and ten hits, earning him the title of Tennessee's DII-A Mr.

In 19 games (ten starts), he compiled a 6-3 record and a 3.06 ERA, holding opposing batters to a .242 average, earning him a spot on the SEC All-Freshman team along with freshman All-American honors.

[13][14] He made his professional debut with the Grand Junction Rockies of the Rookie-level Pioneer League and spent the whole season there.

[27] Following the end of the season, Rolison began playing in the Dominican Professional Baseball League for the Tigres del Licey.

[33] After rehabbing with the Single-A Fresno Grizzlies, Rolison was activated from the injured list on May 29 and optioned to Triple-A Albuquerque.

[37] The same night that Rolison was selected by the Rockies in the draft, controversy emerged after a tweet by him from 2012 resurfaced in which he wrote “Well we have one hope left … if someone shoots him during his speech,” regarding the 2012 United States presidential election.
