After the game was postponed in the top of the second inning on Monday due to heavy showers, the two teams restarted the contest at the same point on Wednesday and were locked in a 2-2 tie at the end of the eighth frame.
Nichirin finally broke the stalemate in the bottom of the ninth when Cameron Isley drew a bases loaded walk to bring home the winning run.
"This win was absolutely huge for us. It's always important to win your first game, but to do it against an established team like Marshall Medical Center is big," said Nichirin coach Bradley Maddox. "Our pitchers looked great on the mound. David came in and threw strikes and Stuart pitched well too. I couldn't have asked for a better outing from them."
Lane Whitesell tallied a double and 2 RBI to pace Marshall Medical Center offensively, while starting hurler Ethan Poteete, relief pitcher Zach Gordon, and Payton Hood all singled.
Nichirin mustered only three hits against Poteete and Gordon, but were aided by five walks and five hit batsmen.
Hunter Bradford doubled and scored a run to account for Nichirin's lone extra base hit of the game, while Hunter Talley and Warner both singled.
Gordon suffered the loss for Marshall Medical Center after giving up one run over three and one-third innings on two hits and two walks.
Nichirin got on the board first when Talley scored on a Looney RBI groundout in the bottom of the fourth inning to make 1-0 after being hit by a pitch and advancing to third on an errant pickoff throw.
Marshall Medical Center mounted an immediate response and pushed across two runs in the top of the fifth inning to grab a 2-1 lead. After drawing a walk, Connor Bush advanced to second on a Nichirin error while Gordon reached first base on the play. Whitesell then plated both runners by lacing a two-run double into the left field.
Nichirin quickly counterpunched and tied the game at 2-2 in the bottom of the fifth when Conner Mealer raced home on a RBI groundout by Josh McKnight after drawing a one-out walk, stealing second, and advancing to third on a wild pitch.
Neither team was able to cross home plate over the next three innings, before Nichirin loaded the bases with one out in the bottom of the ninth thanks to a leadoff double by Bradford and two hit batsmen. Bradford then trotted home when Isley drew a five-pitch walk to give Nichirin the 3-2 victory.
