The road was less kind as they faced Nevada for the second straight night Sunday, suffering their first loss by a 5-4 final.
Stanten Jones got the start for the Mustangs (2-1), tossing 4 1/3 innings, surrendering every run on five hits while striking out six.
St. Joe got on the board first in the top of the third with Michael Schulze plating Kyle Richards on a fielder's choice.
Nevada answered that same frame, scoring on a wild throw from Jones to Joe Koerper. Tanner Glore followed that with an RBI knock to left.
The Griffons handed the Mustangs a chance to tie it in the fifth as Schulze dashed home on a wild pitch, but prevented a lead change after St. Joe had loaded the bases.
Matt Johnson went to Jerad Hawkins in relief after David Chew put Nevada back on top with an RBI single in the fifth. The Griffons opened up for two more runs to jump up 5-2 before the end of the inning.
Hawkins pitched impressively through the final four frames as the Mustangs chipped away. Kyle Simpson cut the lead to two with an RBI in the seventh. Payton Scarbrough then came through with a home run for the second straight ninth, pulling them within one in the ninth.
Simpson came up again with Schulze representing the tying run, but struck out before Schulze was doubled up at second to end it.
The Mustangs travel to face the Ozark Generals with a 5 p.m. first pitch on Tuesday.
