Dayton (1-1) struck first with a pair of runs in the top of the fourth inning to jump out to the early lead. Robby Sunderman drew a walk and later advanced to third on a single through the right side from A.J. Ryan. After a wild pitch moved Ryan into scoring position at second base, Aaron Huesman singled to left to plate both Sunderman and Ryan.
Upstate (1-2) answered with two runs in the bottom half of the fourth on a towering home run from Krider. Spartan catcher Luke Weber drew a two-out walk and came around to score when Krider followed with his first home run of his career.
The Spartans erupted for five runs in the bottom of the sixth inning to open up a 7-2 edge. Samples started the inning by reaching base on a fielding error by Ryan. Back-to-back singles from Tyler Lesch and Weber loaded the bases, paving the way for Krider to drive home two more runs with a single to right field. Drew Fisher, Stephen Dowling and Daniel Fickas each drove in a run in the inning.
Weber tacked on two more runs for Upstate in the seventh inning when he smacked a double down the left field line that drove in Lesch and Samples. Upstate loaded the bases in the bottom of the eighth inning on hits from Dowling and Fickas and a fielding error by the Flyers. Samples followed at the plate and crushed a home run over the left field wall to put the Spartans ahead 13-2 on the grand slam.
Zac Manuppelli (1-0) picked up the win for Upstate after pitching a scoreless sixth inning. Starter Richie Lacell, who took a no decision, pitched five innings and allowed two runs on three hits while striking out six. Daniel Seeba and Samples also saw action in relief for Upstate.
Dayton starter Joe Wahl (0-1) allowed seven runs on eight hits in 5.1 innings of work and suffered the loss.
Upstate returns to action Monday at 1 p.m. when the Spartans host SEC foe Kentucky from Harley Park.
