Gonzalez got off to a strong start with four goals during the first quarter to put the Lady Wildcats up by a point. She scored nine points during the next two frames, but Slater couldn't pull away from the Lady Tigers because sophomore Kerrigan Wessing buried four three-pointers and sophomore Melissa Schlotzhauer hit five shots during the same stretch.
The Lady 'Cats went into the final stanza with a six-point lead, which senior Olivia Knox helped extend with a pair of bombs. Slater sank six of 10 free throws down the stretch.
Although Pilot Grove shot a respectable 41.5 percent from the field, the Lady 'Cats' 51-17 dominance of the boards gave them an advantage of 71 to 53 in total attempts and 23-8 in free-throw opportunities.
Schlotzhauer wound up with a game-high 21 points and Wessing had 17, but the rest of the Lady Tigers (3-5) contributed only seven points while Slater got twice that many from its bench -- led from freshman Krysta Cramer.
Gonzalez finished with 18 points and 20 rebounds and Boston added 12 points and 17 boards for the Lady 'Cats (6-5).
A 46-28 roll through the second and third periods led the Pilot Grove boys to an 82-51 victory over the Purple.
During that span, senior Dylan Twenter and junior Colton Glenn combined for half of the Tigers' points.
Twenter led all scorers with 21 points and sophomore Jake Leverton knocked down five treys on his way to 19 points for Pilot Grove (8-1), which will return to Slater next month for the Wildcat Classic.
The 'Cats (3-7) got 17 points from junior Caleb Pemberton and 12 from junior sixth man Tyler Buglovsky.
Both Slater teams will take part in the Otterville Holiday Classic, the fifth-seeded boys facing Tuscumbia on Dec. 29 and the No. 3 girls going up against Lincoln on New Year's Eve.
