Gilman moved up to No. 1 in this week's Maryland High School Football Media State Poll, taking all 12 votes for the top spot.
The Greyhounds, No. 2 last week, took over the top spot thanks to Quince Orchard's 52-27 upset of previous No. 1 and defending Class 4A state champion Northwest (8-1).
Gilman defeated Calvert Hall, 35-7, Friday and has won eight straight games since falling to St. Edward (Ohio) and Paramus Catholic (N.J.).
The Greyhounds have clinched a share of the Maryland Interscholastic Athletic Association A Conference title and can win it outright with a win over McDonogh on Saturday. Their second win of the season came 20-0 over Good Counsel, which is now ranked second in the state poll.
Broadneck (9-0) is the next Baltimore-area team in the poll, holding at No. 8 after a 28-25 win over Meade. Franklin (8-1) remained at No. 10 with McDonogh (6-3) moving up one to No. 12 and Mount Saint Joseph (8-2) moving up one to No. 13.
No. 19 Archbishop Curley, which is 9-0 heading to Saturday night's MIAA B Conference championship, moved up two spots as did No. 20 Arundel (8-1) and No. 21 Howard (9-0).
With their losses, St. Frances (4-5) fell from No. 11 to No. 23 and Calvert Hall (5-4) dropped from No. 18 to No. 24. Old Mill, Mervo, South Carroll and Oakland Mills also received votes but not enough to crack the Top 25.
