Here are my four candidates that best fit that description: Tesoro, Valencia, Los Alamitos and Santa Ana.
Tesoro is dominating the South Coast, in first place at 4-0-2.
Valencia is in first in the Empire League, at 4-1, with victories over Sunny Hills and Fullerton in preseason.
Santa Ana is the only team to defeat Saddleback this season.
Los Alamitos is 4-2 in the Sunset and atop the standings.
