Paul Piatelli delivered a game-winning single in the bottom of the seventh inning to give St. Lawrence University's baseball team a 5-4 win in game one of a Liberty League doubleheader with Union College and Khifer O'Connor went 4-4 and drove in three runs with Kyle Donaldson pitching the Saints out of trouble in the eighth to complete the sweep with a 7-5 win in game two.

The Saints improved to 14-4 overall and 7-2 in Liberty League play while Union is now 10-9 overall and 5-5 in league play. The two teams will play another doubleheader starting at noon Sunday.

In game one, the winning rally started when Bryan Palermo led off the bottom of the seventh by being hit by a pitch from Union's Chris Pignatello. Carter Franz sacrificed him to second and Khifer O'Connor was intentionally walked to set up a possible double play. Jeff Kott was then hit by a pitch to load the bases and Piatelli lashed a single to right center to score Palermo with the winning run.

Union took a 1-0 lead off Saint starter Jason Conde in the top of the third when Vince Esposito lofted a high fly ball which rode the wind over the left field wall at the 370 mark for a home run, but the Saints came right back to score four in the bottom of the inning.

Matt D'Auteuil started the rally with a one-out single to left for the Saints' first hit off Union starter Dane O'Neil. Ethan Braddock then singled to center with D'Auteuil moving to third. Palermo drew a walk to load the bases and Franz hit a hard grounder which was misplayed at second, scoring D'Auteiul and Braddock. O'Connor then delivered a single to center to score Franz and Palermo giving the Saints a 4-1 lead.

Union tied it with a trio of unearned runs off Conde in the top of the fifth. Tyler Heck's two-out bases loaded triple produced the runs. Conde improved to 3-2 on the season with the complete game win, allowing four hits, walking three and striking out five in seven innings.

Matt Skelly improved to 3-0, pitching into the eighth in game two, but Union scored twice and had the bases loaded with none out before Donaldson came on and got the Saints out of trouble with a pair of strikeouts and a tapper back to the mound to prevent further scoring and earn his second save of the year.

Union opened the scoring in the top of the third as Sam Caruso singled and John Moore doubled him home, but the Saints came right back to take a 4-1 lead with a big bottom of the inning. Palermo walked with one out and Franz singled to right. O'Connor then doubled to score Palermo and Jeff Kott hit a three run homer off Union starter Phil Kemp.

The Saints picked up a single run in the fifth as Brian Magoveney tripled in the run and after Union got two back in the top of the sixth on a double by Heck and a sacrifice fly by David Peretti, the Saints came right back with two of their own in the bottom of the inning as Mark Syron singled, Franz walked and O'Connor delivered a two-run double for a 7-3 lead.

A single by Jason Cohen and a double by Vince Esposito started the Union eighth with Andrew Weitzel coming on for Skelly. Dylan Katz-Wicks singled home Cohen and Heck doubled, scoring Esposito to cut the lead to 7-5. Donaldson came in and gave up a walk to load the bases, but then struck out two straight Union batters and enticed an easy grounder back to the mound for the final out of the inning to save the game.
