SAN DIEGO (Interstat) — Jayton Greer hit two home runs, including a go-ahead grand slam in the eighth inning, and drove in five runs to lead San Diego past Loyola Marymount 7-3 on Friday night at USD Sports Center.

Greer, the Toreros’ designated hitter, finished 3 for 4 with a double, two homers and five RBIs. He gave San Diego a 3-3 tie with a solo shot in the seventh inning and then broke the game open with a four-run blast in the eighth.

Drake Frize earned the win for San Diego (19-29) after pitching six innings, allowing one earned run on three hits while striking out nine. Aídan Gonzalez earned a hold with 1 2/3 scoreless innings, striking out one.

Zion Williams hit a two-run homer for Loyola Marymount (12-43) in the top of the eighth to briefly give the Lions a 3-2 lead. DJ Ghiorso walked and scored twice for the Lions.

Adam Behrens started for Loyola Marymount and pitched 6 1/3 innings, allowing three runs on two hits — both to Greer — with six strikeouts. Alec Johnson took the loss after surrendering four runs in 1 2/3 innings.

The game was tied 2-2 after the second inning. San Diego took a 2-0 lead in the bottom of the second when Connor Meidroth doubled down the right-field line, scoring Greer and Aídan Gonzalez. Loyola Marymount answered in the top of the sixth when Mhoon singled to right-center, scoring Ghiorso from second base.

The score remained 2-2 until the bottom of the seventh, when Greer led off with a solo homer to deep right field, his first of the season, putting San Diego ahead 3-2.

Loyola Marymount surged back in the top of the eighth. Ghiorso walked and advanced to second on a wild pitch. After a strikeout, Williams homered down the left-field line, his fourth of the season, scoring Ghiorso and giving the Lions a 3-2 lead.

San Diego answered immediately in the bottom half. Moran singled, advanced to second on a sacrifice bunt, then Gauna reached on a bunt single. After a mound visit, Lobliner walked to load the bases. Greer then launched his second homer of the game, a grand slam to center field, clearing the bases and putting San Diego ahead 7-3.

The Lions threatened in the top of the ninth after Friend reached on a fielding error by third baseman Meidroth, but a strikeout, a fielder’s choice and a flyout ended the game.

Loyola Marymount’s eight-game losing streak extended to nine. The Lions have lost 18 of their last 20 games. San Diego snapped a two-game skid and improved to 2-1 in the season series against Loyola Marymount, having won 17-8 the previous night.

The two teams meet again Saturday for the series finale.
