The Bucs move to 8-3 on the year with the split, while Holy Cross is 3-3 after Saturday's doubleheader.
Game 1 – CSU 1, Holy Cross 0 (15 inn.)
Schroff worked the opening seven innings and scattered five hits. Austin Weekley followed with four strikeouts in three innings, and Tyler Weekley (WP, 1-0) struck out five over the final five frames.
The scoreless start was the second scoreless start of over six innings from Schroff this season, while the Weekleys have combined to work 22 scoreless innings this season.
"Credit our pitchers and defense for not giving up anything for 15 innings," CSU head coach Stuart Lake said following the doubleheader. "I thought they went out and took game one for us. To not give up a run over 15 innings is pretty amazing. Our offense never really got going today and we need to get that fixed for tomorrow. We also need a good start out of Andrew Tomasovich."
Charleston Southern won the game in the 15th inning when Sam Remick scored on a sacrifice fly by Alex Tomasovich to end the marathon. Remick reached on an error by shortstop Nick Lovullo, then moved up on a single by Nate Blanchard and a wild pitch, setting the stage for Tomasovich.
Blanchard led the Bucs with a 3-for-5 day at the plate in win. Tomasovich added two hits and the game's lone RBI.
DH Jack St. Clair was 2-for-7 for Holy Cross.
Game 2 – Holy Cross 7, CSU 1
Holy Cross' Brandon Cipolla had a three-run double in the Crusaders' scored four runs in the fifth inning to break a 1-1 tie and take the nightcap.
Starter Phil Reese (WP, 1-1) worked six innings and surrendered only four hits.
Cipolla finished 1-for-4, but scored twice. Lovullo was 3-for-5 and also scored two runs.
The two teams play again on Sunday and Monday. Both games start at 2 p.m. at CSU Ballpark.
