Petaluma High's T-Girls are both hosting and playing in the championship game of the first Sonoma County League Tournament. The tournament, like its league baseball counterpart, pits the top four teams in a single-elimination tournament that has no bearing on the league standings.
League champion Petaluma won its first-round game easily, defeating fourth-place Piner Wednesday afternoon, 13-0.
The T-Girls will face the winner of Thursday's Analy vs. Sonoma Valley game Friday at 4 p.m. for the league championship.
Dana Thomsen (three innings) and Katie Bisges (two innings) allowed Piner just one hit.
Every player on Petaluma's 13-person roster had a hit in the game, with the T-Girls totaling 18 in five innings.
Bisges, Barnacle and Thomsen each had two hits for the T-Girls.
