TYSONS, Va. – Richmond hit five home runs, including two each by Jordan Jaffe and Jack Arcamone, to defeat top-seeded Saint Louis 13-10 Wednesday afternoon in the second round of the Atlantic 10 Championship at Capital One Park.

The top-seeded Billikens hit four round-trippers themselves, scoring eight runs in the final four innings in an effort to rally, but Richmond’s bats stayed hot. The Spiders (26-31) advance to Friday’s semifinals, while Saint Louis falls into the consolation bracket.

Jaffe was 3-for-4, hitting two-run homers in the first and fifth innings, and added an RBI single in the seventh to collect five RBI. Arcamone’s dingers came in the third and seventh innings. Both shots were of the three-run variety, giving him a game-high six RBI. Fourth-seeded Richmond’s other home run came off the bat of Connor Larson, who had a sixth inning solo shot.

The four Billiken (37-15) long balls were courtesy of just two players, Tyler Fogarty and Easton Richter, who each had two. Richter’s first, a two-run blast, came in the fourth right after Fogarty broke up a budding no-hitter with a single to left.  Fogarty hit a leadoff solo shot in the sixth before Richter struck again in the seventh with a three-run round tripper as SLU tried to rally, down 13-5 entering the inning. Fogarty had a two-run homer in the eighth that pulled the Billikens within three, but those were their final runs of the game.

The teams combined for 24 hits as Esteban Rodriguez (5-2) earned the victory with 5.0 innings pitched, allowing two runs on five hits with six strikeouts. Jackson Holmes took the loss for Saint Louis, with four runs on three hits.
