Ben Richard took the loss for Alpines while Ryan Nason and Ryan Evans each went 1-for-2 for the host Alpines.
In Game 2, the Islanders broke open a 2-2 game with three runs in the fifth en route to an 8-3 win.
Brett Hicken threw five solid innings, allowing two hits striking out eight. Porter Smith struck out four more during the last two innings.
Gallant and Matt Barlow each had two hits while J.J. Oram scored three times and stole five bases to pace the offence.
Dawson Griffin took the loss and had three hits.
The Islanders are back in action next weekend with a pair of doubleheaders. They host Chatham on Saturday in Charlottetown and Saint John Sunday in Summerside. Game 1 on both days begins at noon.
