Kevonte Mitchell blasted a grand slam over the LF fence and onto the south bank of the Loop 202 Red Mountain Freeway to cap a nine-run explosion in the bottom of the 5th inning as the Myrtle Beach Pelicans (Cubs Hi-affiliate) turned a 5-0 deficit into a 9-5 lead and then hung-on for dear life to edge the Inland Empire 66ers (Los Angeles Angels Hi-A affiliate) 9-8 on Field #6, and RHSP Erich Uelmen (Cubs 2017 4th round draft pick - Cal Poly SLO) hurled four innings of one-run ball with five strikeouts, no walks (72% strikes), and 6/0 GO/AO, and Cam Balego (RBI triple), Alexander Guerra (RBI double), and Luis Hidalgo (RBI single) contributed run-scoring hits to stake the Cubs Lo-A South Bend affiliate to a 4-1 lead, but the Burlington Bees (Angels Lo-A affiliate) came-back in the late innings to tie the game at four and then the potential winning run was picked-off 2nd base with no outs in the bottom of the 9th to thwart a Cub plan to plate the winning run with a sac bunt and maybe a sac fly, as Burlington and South Bend played to a 4-4 tie on Field #5, in Cactus League Minor League Camp doubleheader game action Tuesday afternoon on John Arguello Way at the Riverview Baseball Complex in Mesa, AZ.
