Robertson remained unbeaten in the 2015 baseball season, sweeping Capital on Tuesday at Memorial Middle School’s Whorton Field.
The Cardinals won 5-1 in game one after getting off to a 3-0 head start in the first inning.
Eleazar Allen, who started at pitcher, helped himself by hitting a two-run double in that opening frame, scoring Colin Pedro and Nate Archuleta.
Pedro finished 2 for 4. Keanu Baca went 2 for 3. Archuleta was 1 for 1 with a walk and a hit by pitch.
