The Runnin' Bulldogs (19-13-1) won their fourth in a row, scoring three runs in the fourth and sixth innings and two runs in the seventh and eighth.
Gardner-Webb got a sacrifice fly from John Harris to go up 1-0 in the first, and took a 2-0 lead in the third when Scott Coleman swiped home on a decoy play before the other base runner was tagged out by the Lions (10-28).
Benji Jackson parked a two-run home run to make the score 5-0 in the fourth and - after Mars Hill scored its first run in the top of the sixth – Gardner-Webb scored on a wild pitch, an RBI single from Coleman and an RBI double from Brad Collins to go up 8-1 after six complete.
Nick Triplett collected his first hit of the season with an RBI knock in the seventh to put Gardner-Webb up 10-1, sliding in safely to third base when the ball got past two Lions in the outfield. Even Hyett also collected his first hit of the season in that inning, part of a three-hit frame for the 'Dogs.
Mars Hill got a sacrifice line drive to right from Phillip Carroll to trim the lead to 10-2 in the top of the eighth, but Tyler Best roped a two-run single to left in the bottom half of the eighth to provide the final margin.
Hunter Smith (1-0) worked 3.0 predetermined innings to pick up the first win of his career in his first mound start. The Whiteville, N.C., freshman was efficient, using just 22 pitches and scattering two hits in his three scoreless frames.
Mars Hill starter Thomas Timmerman (1-3) took the loss, allowing two runs on three hits and five walks in 3.0 innings. The Lions used eight different pitchers Wednesday night.
Mars Hill had eight hits in the game, with Jacob Rand (2-for-3) the lone man with multiple safeties.
Gardner-Webb returns to action on Friday night, hosting North Carolina A&T at 6:00 in John Henry Moss Stadium / Bill Masters Field. The game will air live on the Big South Network (bigsouthsports.com).
