Jake Wang tripled, singled, scored twice and drove in three runs for the Bears (3-2, 1-0), who host the previously undefeated Cougars in a PAL contest Thursday at 4 p.m.
Jake Albro also drove in a run for M-A, which won its third straight. Anthony Waller added two hits.
The Bears are looking to take another step forward under David Klein this season, who took over in 2017, a year after M-A finished 5-22, 2-12.
The Bears were 12-15, 6-6 in Klein's first year and finished 14-12, 8-6 last year, which included a 10-1 mark at home.
Half Moon Bay and M-A split their season series last year, each winning at home.
M-A threw its first shutout since Tommy Eisenstat and Waller combined on a 1-hitter in a 1-0 win over Terra Nova last April 11. Albro scored the only run of the game.
Discher allowed all four hits during his five-inning stint. He struck out six and walked one. Zeien threw two hitless innings to finish the game.
