On Saturday, Nevada finally exploited a crack in the armor and hung a season-high eight runs on St. Joseph, handing them their first loss, 8-1.
Pitching around spurts of rain at Phil Welch Stadium, Dixon Marble (0-1) allowed a game-opening RBI single to Coday Farrell in the first. The Griffons plated three more runs in the third and chased the Mustangs' starter after five innings.
He allowed five runs on seven hits, while striking out four batters.
Sloppy defense was a regular sight again as each team committed three errors. The Mustangs (5-1, 1-1), however, couldn't capitalize on fielding miscues, plating their lone run in the fourth when Evan McDonald grounded into a fielder's choice to plate Joe Koerper.
Payton Walker recorded six strikeouts, allowing four hits and one run over five frames. St. Joseph stranded 10 batters overall.
Jayme Lovelace also allowed five hits and three runs through 2 1/3 innings in his first relief appearance of the season.
The Mustangs hit the road for the first time Sunday to face Nevada again.
