The projected MLB arrival time (per MLB Pipeline) for Petal’s Demarcus Evans is 2020. The big right-hander, pitching at Double-A Frisco in the Texas system, appears to be running on schedule. Evans, 22, has not allowed an earned run in nine straight appearances and has a 1.40 ERA over 15 games since being promoted from Class A Down East in late May. He posted an 0.81 and six saves for Down East. On Thursday night, Evans worked a clean ninth inning in a 4-2 win over Tulsa to notch his first Double-A save. He has 33 strikeouts and 13 walks in 19 1/3 innings. The 6-foot-4, 270-pound Evans, a 25th-round draft pick out of Petal High in 2015, throws what is described as an exploding fastball and a quality curve. He has averaged 13.7 K’s per nine innings in his five-year pro career. It wouldn’t be a surprise to see him move up to Triple-A before this season ends. P.S. Playing shortstop for Tulsa in that Texas League game was Errol Robinson, the former Ole Miss star. He had two hits, including a homer, and boosted his average to .318 for the Los Angeles Dodgers’ affiliate. (He did not face Evans.) Robinson started this season in Triple-A but struggled (.220) and was sent down in late June to Tulsa, where he has begun to perk up.
