Katie Guenin scored twice Menlo-Atherton clinched its first PAL Bay Division girls' soccer title in 19 years, beating visiting Aragon, 3-0, on Saturday.
The Bears (13-4-1, 12-0) host Capuchino at 4 p.m. Tuesday and finish the regular season at Woodside on Thursday at 4 p.m.
The Vikings (11-0-4, 7-0-4) have one match remaining, against visiting Fremont (5-12-2, 0-10) on Tuesday at 3:30 p.m. Mountain View (14-1-3, 7-1-2) is the only other school who can ascend ahead of Paly and has two games.
If Palo Alto wins Tuesday, the Spartans, who lost to and tied the Vikings during the regular season, would need to win both of their remaining games, against Santa Clara (9-2-6, 5-1-4) on Tuesday and at Los Gatos (10-5-3, 4-3-3) Thursday.
The Central Coast Section seeding meeting is Saturday and could be interesting depending on this week's results. Playoffs begin Feb. 21. Palo Alto could enter the playoffs with a streak of 17 consecutive shutouts (or roughly 1,280 minutes).
M-A has little worries, other than holding onto its undefeated league season and staying healthy. The Bears, who were 0-3-1 to start the season, will compete in the Open Division this year after winning the CCS Division I title last year.
Palo Alto beat M-A, 5-0, early in the season but the Bears played Mountain View to a tie. M-A's other losses are 1-0 to Mitty (13-1-2, 5-1-2) and 2-1 to Presentation (8-4-6, 3-3-3).
Menlo-Atherton grabbed the early lead against the Dons. Junior Diana Morales provided a perfect assist to junior Josephine Cotto, who drilled it into the net for a 1-0 score at the half.
The Dons thwarted several scoring attempts by the Bears until the second half, when Morales produced another great assist that Guenin transformed into a goal, sending a long ball over the keeper's head.
M-A's midfield prevented an offensive attack by Aragon, with stellar play by seniors Alissa McNerney, Nicole Salz, Margaret Child, and sophomore Yara Gomez along with Cotto.
Guenin added an insurance goal, rewarding the precision passing of Cotto to Child, whose assist allowed Guenin to fire a rocket high into the left corner of the net.
The Dons had no room to roam against the Bears defense, which also included seniors Ali Sivilotti and Allison Galbraith, juniors Olivia Shane and Grace Brieger and dependable keeper junior Breanna Sandoval.
