Former Northwestern State All-American Adam Oller is back in affiliated baseball.

Coming off a dominant run with the Frontier League’s Windy City Thunderbolts, Oller’s contract was purchased by the San Francisco Giants, who assigned the right-handed pitcher to their Class A affiliate, the Augusta Green Jackets.

Oller, named to All-American teams by the American Baseball Coaches Association and Collegiate Baseball Magazine In 2016, went 2-1 with an 0.67 ERA and 45 strikeouts in 27 innings for Windy City. He walked only two batters in that time and left the Frontier League as the league leader in wins, WHIP (0.63) and strikeouts.

He joins former Northwestern State teammate Kwan Adkins in the Giants organization. Adkins and Oller played two seasons together at NSU, helping the Demons reach the Southland Conference Tournament in 2015 and 2016.

A three-year letterman at Northwestern State, Oller was a 2014 Freshman All-American and the 2016 Southland Conference Pitcher of the Year. He was the 20th-round draft pick of the Pittsburgh Pirates and spent parts of three seasons in the Pirates organization.

Oller finished his Demons career in the top 10 in career starts (43, 4th), ERA (2.06, 4th), innings pitched (310 1-3, 4th), wins (20, 8th), strikeouts (188, 7th), and winning percentage (.741, 9th).

Oller joins Adkins and another former teammate, Nick Heath (Double-A Northwest Arkansas) as former Demons in affiliated baseball. Heath currently leads all of Minor League Baseball in stolen bases with 30.
