The section 5 girls lacrosse post-season tournament begins Saturday with four first-round games in class B. All first-round and quarterfinal games will be hosted by the higher-seeded team. All semifinal games will be played at neutral sites and, for the first time ever, the University of Rochester will host the final game for each of the four classes.

Class A

1. Penfield
2. Fairport
3. Rush-Henrietta
4. Greece Storm

Penfield looks to bounce back from a disappointing semifinal loss to Pittsford last season. The Patriots lost only three games all season, each of them by only one goal, and two of them in overtime. Fairport is the defending class A champion in section 5, and comes into the postseason riding a eight-game winning streak. Rush-Henrietta, which lost to Fairport each of the past two years in postseason play, hopes to flip the script this year.

 Class B

1. Victor
2. Pittsford
3. Mercy
4. Irondequoit
5. Spencerport
6. Brighton
7. Churchville-Chili
8. Eastridge/BK
9. Canandaigua
10. Hilton
11. Schroeder
12. Thomas

Victor has won the New York State class B championship in each of the past three years, and has fielded another strong squad this season. The Blue Devils face a potential quarterfinal matchup against Canandaigua, the last class B team to defeat them. Pittsford earned the number two seed in its first season in class B. The Panthers will take on the winner of the first-round game between Churchville-Chili and Hilton. Mercy, last season's class C champion in section 5, has a potential quarterfinal matchup against Brighton. The Bruins come into the playoffs on a roll, having recently recorded road wins against both Canandaigua and Honeoye Falls-Lima. Irondequoit, the number four seed, has a likely quarterfinal matchup against Spencerport, the team that bumped the Eagles from the playoffs last year. Eastridge/BK enjoyed a successful run in the regular season but faces a difficult first-round opponent in Canandaigua.

 Class C

1. Pal-Mac
2. Geneva
3. Honeoye Falls-Lima
4. Aquinas/WOIS
5. Livonia-Avon-Geneseo
6. Wayne
7. Brockport
8. Newark-Midlakes

Pal-Mac, last season's class D runner-up in section 5, moved up to class C this season and claimed the number one seed. Geneva enjoyed its most successful season in years but faces a potential semifinal roadblock in the form of Honeoye Falls-Lima, last season's class C runner-up in section 5. The number three-seeded Cougars, who defeated Pal-Mac 17-5 early this season who logged a recent victory over Pittsford, take on Wayne in the quarterfinals. Aquinas/WOIS and Livonia-Avon-Geneseo will match up for the third time this year; the visiting team won each of the previous games.

Class D

1. Penn Yan
2. Waterloo
3. Mynderse-Romulus
4. Marcus Whitman

Penn Yan is the number one seed, having recorded victories this season over Brighton, Canandaigua, Irondequoit, and Honeoye Falls-Lima. The Mustangs will face Marcus Whitman in the first semifinal game. In the second semifinal, Waterloo, the number two seed, looks to continue its winning ways against Mynderse-Romulus; the Tigers have defeated the Blue Devils seven consecutive times, including twice already this season.
