The 66ers and Quakes had been mired in third and/or fourth place in the California League’s South Division for much of the season, but on Wednesday, both teams knocked off the top two in the division.

The Sixers, behind Alberto Bastardo’s six inning, one earned run effort, knocked off the first-place Mavericks 6-2 to take three out of four in the four-game series at Stater Bros. Stadium.

The Quakes, meanwhile, outlasted second-place Lake Elsinore 1-0 in Brian Walker’s single with the bases loaded in the bottom of the 10th at the Epicenter.

The Quakes start a four-game series at Lancaster on Thursday, while the Sixers are off before beginning a four-game series at Lake Elsinore on Friday.
