Stewart was the fourth overall pick of the 2013 First-Year Player Draft, and he is pitching well in his first full professional season. Stewart has made six starts this season and has a 2.35 ERA in 30 2/3 innings. He has struck out 23 batters and walked eight. Stewart's 0.88 WHIP is the best in the Midwest League.
Jorge impressed in the Appalachian League last year, but he has struggled in his introduction to full-season ball. In 26 1/3 innings this season, Jorge has an 8.89 ERA and a 1.71 WHIP.
Stewart and Jorge will face a Peoria lineup that is led by catcher Carson Kelly and shortstop Juan Herrera, the Cardinals' Nos. 8 and 15 prospects. Kelly is batting .252 with a .720 OPS in 27 games this season as he works to make the conversion from third base to catching. Herrera, whom the Cardinals acquired from the Indians last July in exchange for relief pitcher Marc Rzepczynski, is batting .283 with a .743 OPS in 29 games.
In addition to Stewart, several other pitchers ranked in the Top 100 are scheduled to start Wednesday, including Henry Owens (No. 28), Eddie Butler (No. 37), Allen Webster (No. 42), Jesse Biddle (No. 49) and Justin Nicolino (No. 74). Fans can watch all but Biddle on MiLB.TV, beginning at 1:05 p.m., when Butler and Double-A Tulsa host Springfield.
