Wyatt Short, the former Ole Miss standout from Southaven, has been promoted to Triple-A Iowa in the Chicago Cubs’ system and pitched 1 2/3 scoreless innings in his debut on Sunday. Short, a 5-foot-8 left-hander, posted a 1.63 ERA and nine saves at Double-A Tennessee, where he was a Southern League All-Star this summer. He has a career 2.37 ERA with 16 wins and 38 saves in 136 relief appearances. Short was a 13th-round pick by the Cubs in 2016 and is one of six Mississippi products now in that organization. Ex-Mississippi State star and veteran big league pitcher Kendall Graveman signed as a free agent in the off-season but is on the injured list recovering from Tommy John surgery in July 2018. George County High alum Justin Steele is also on the Cubs’ 40-man roster, but the injury-hampered top 20 prospect, a 2014 draft pick, is on the IL at Double-A Tennessee. With Short at Iowa is Delta State product Trent Giambrone, the Cubs’ No. 28 prospect (per MLB Pipeline); the versatile Giambrone, a 2016 draftee, is batting .242 with 23 home runs. Playing the infield at Class A Myrtle Beach are former Southern Miss star Luke Reynolds and Itawamba Community College product Delvin Zinn. Zinn, a 2016 draftee, is hitting .233 with 12 RBIs and eight steals in 35 games since he moved up from low-A ball in early July. Reynolds, C-USA player of the year in 2018 and a 10th-round pick that year, was demoted from Myrtle Beach to low-A South Bend when Zinn moved up. He returned to the Carolina League on Aug. 2 and is 10-for-33 with a homer and five RBIs since.
