The Quakes came up short to San Jose, losing 9-4.
Meanwhile, the 66ers downed High Desert 2-1 in 12 innings.
High Desert clinched the second-half title on Thursday, after winning the first-half crown.
So, the last 2 playoff spots will be wild-cards.

For the Sixers, Taylor Lindsey singled with one out in the bottom of the 12th, his fourth hit of the game. Ryan Jones walked. Kaleb Cowart then hit a grounder.

Jett Bandy added three hits for the Sixers.
Eswarlin Jimenez, in his Cal League debut, allowed eight hits and one run in seven innings, while striking out three. Carmine Giardina, Daniel Tillman and Eric Cendejas (4-3) provided scoreless relief.
For the Quakes, they led 4-2 through five innings. But San Jose scored 1 in the sixth, 2 in the seventh, three in the eighth and one in the ninth to win going away.
The game was a matchup of big-league pitchers. San Francisco Giants reliever Brad Penny pitched one inning for San Jose, allowing one unearned run.
