Glendora (14-2) opens the Baseline League tonight at Rancho Cucamonga (14-3) at 6:30 p.m., but each week in the Baseline is test. Every team has a winning non-league record. Etiwanda (9-2), Los Osos (11-4), Upland (10-5) and Alta Loma (8-6) easily make this one of the tougher leagues in the Southern Section top to bottom. Glendora probably still needs a healthy Nick Colletta, who averaged 19 points in just five games last year but sat out most of it with back issues. But in any case, Tartans coach Mike LeDuc always gets the most out of what he has, and this year should be no different.
