Siena’s Vincent Citro hit a walkoff single with the bases loaded in the 10th to give the Saints their first postseason win in program history with a 9-8 victory over Dallas Baptist on Saturday.After a pitcher-dominated first day in the NCAA Fort Worth Regional at Lupton Stadium on Friday, Siena eliminated Dallas Baptist in an offense-heavy game on Saturday.Citro’s game-winning hit came off one of the best relief pitchers in the nation in Brandon Koch, who lost his first game of the season.“It feels fantastic. I’m proud of our school and baseball alumni,” said Siena coach Tony Rossi, who has been with the school for 45 years. “We’ve been in a few [postseasons], but it’s our first win. It was a tough one, but I give credit to these guys. It’s a great win for our program, our school and the community.”It was also the first win in a regional by a Metro Atlantic Athletic Conference school since Manhattan beat Nebraska in 2006.After falling behind 7-0 after two innings, the Saints (27-32) scored two in the bottom of the second after Dave Hoffmann’s RBI single and Mike Allen’s RBI hit-by-pitch with the bases loaded.The Saints added three more runs in the third to cut the deficit to 7-5 after Citro’s sacrifice fly.Trailing by one in the seventh, Siena’s John Rooney drove in the go-ahead run with a two-RBI single to give the Saints an 8-7 lead.The Patriots (40-21) sent 10 players to the plate in the first inning, scoring five times.Saints starter Ed Lewicki returned for the second inning and allowed two runs before being replaced by Neil Fryer, who pitched the game’s final nine innings, a career high, on 129 pitches, allowing six hits and striking out five..Siena will play Sunday, awaiting the loser of Saturday night’s game between TCU and Sam Houston.
