Pitcher Jayson Aquino began his professional career in the Colorado Rockies system in 2010 at 17 years old. The signing scouts were Frank Roa, Jhonathan Leyba and Rolando Fernandez. He was 4-3 with a 1.02 ERA and 0.714 WHIP in 12 starts for the DSL Rockies his first year, then went 8-2, 1.30 with a 0.859 WHIP for the same club in 2011. Between the DSL Rockies and Grand Junction Rockies in 2012, Aquino was 10-1 with a 1.66 ERA and 0.895 WHIP in 16 starts. Through his first three seasons, Aquino was 22-6 with seven complete games, three shutouts and a 1.39 ERA in 42 starts. In 259 2/3 innings, he allowed just 40 earned runs, 167 hits and 51 walks (for a 0.840 WHIP) while striking out 249 batters. He was a Dominican Summer League Mid-Season All-Star in 2010. Going into 2013, he was ranked the #9 prospect in the Rockies chain by Baseball America.
His stateside career got off to a rocky start. Between the Tri-City Dust Devils and Asheville Tourists in 2013, he was 0-10 with a 4.34 mark. Then he went 5-10, 5.13 in 18 starts between the Modesto Nuts and Tulsa Drillers in 2014. Nevertheless, he earned a spot on the Salt River Rafters in the Arizona Fall League, going 2-0 with a 3.38 mark in four starts. On February 4, 2015, Aquino was traded to the Toronto Blue Jays for pitcher Tyler Ybarra. On May 10th, he was traded to the Pittsburgh Pirates for cash, then on July 29th, he was traded to the Cleveland Indians for cash. Between three systems that year, he was 5-10 with a 3.28 ERA in 24 starts. Contrast his first three campaigns (2010-2012) with his next three (2013-2015). In the latter grouping, he was just 10-31 with a 4.16 ERA in 57 games. He had just one complete game and no shutouts, while his WHIP was 1.32.

On December 9, 2015, he was claimed off waivers by the St. Louis Cardinals. He was traded to the Baltimore Orioles for cash on April 7, 2016. He began the year with the Bowie Baysox, but on July 4th, was promoted to the majors without ever playing at Triple A. He debuted that day, pitching two-thirds of an inning unscathed against the Los Angeles Dodgers, retiring both batters he faced: Chase Utley and Corey Seager. On July 7th, he was optioned back to the minors. He was an Eastern League Mid-Season All-Star in 2016. He finished 2016 with 3 big league appearances and tacked on 4 more for the O's in 2017, pitching to a total of a 6.32 ERA in 15 2/3 innings. He was released in June 2018 while pitching in the minors and bounced around the independent leagues since.
