Old rivalries, new rivalries and everything in between define this field hockey season as many of the best teams cross league boundaries to find additional challenging opponents. A lot of competition awaits them at home too. Here’s a look at some of the match-ups that stand out:

Archbishop Spalding at Broadneck, Sept. 10, 1:30 p.m.

In an early No. 1 vs. No. 2 showdown, top-ranked Archbishop Spalding will try to extend its seven-game win streak against one of their top public school rivals at the Broadneck Tournament. The Cavaliers won 3-1 last season and Broadneck hasn’t beaten them since 2011.

Glenelg at Broadneck, Sept. 13, 6:30 p.m.

Two strong contenders for state titles face-off in this meeting between the defending Class 2A champion Gladiators and Class 4A quarterfinalist Broadneck. The Bruins lead the series 2-1-1, winning the most recent contest 5-1 two years ago. Glenelg last won in 2016.

Hereford at Dulaney, Sept. 13, 5:15 p.m.

Baltimore County’s top two teams have played for the county title 11 times in 12 years with Hereford winning 10. Eight times, one goal has made the difference and the Bulls won last year in a shootout. Dulaney has won five of the past seven regular-season games, but the Bulls won last fall.

St. Paul’s School for Girls at McDonogh, Sept. 14, 5:45 p.m.

Last year’s Interscholastic Athletic Association of Maryland B Conference champion St. Paul’s begins its move to the A Conference with McDonogh. The Eagles managed a 3-2 victory in overtime last fall, but the Gators would like to avenge that and settle into the top conference.

St. Timothy’s at Annapolis Area Christian School, Sept. 28, 4:15 p.m.

St. Timothy’s nipped the Eagles 1-0 three times last season, including in the Interscholastic Athletic Association of Maryland C Conference final. Both regular-season games went to overtime. This is the first of two regular-season opportunities for Annapolis Area Christian to flip the outcome.

Century at Manchester Valley, Sept. 29, 4 p.m.

Last fall, the Carroll County champion Knights edged Manchester Valley 1-0 during the regular season. The Mavericks, however, avenged that in the regional final and went on to the Class 2A state semifinals. With both teams rebuilding, this game could be just as close.

North Harford at C. Milton Wright, Oct. 3, 6:45 p.m.

The Harford County foes split a pair of one-goal games last fall, but the Hawks beat C. Milton Wright, 1-0, in the regional semifinal en route to the Class 2A state quarterfinals. The Hawks aim to challenge the defending champion Mustangs for the Upper Chesapeake Bay Athletic Conference title.

Severna Park at Broadneck, Oct. 11, 6:30 p.m.

The Anna Arundel County rivals split their first two meetings last season before the Falcons edged Broadneck in the Class 4A state quarterfinal, 1-0, before going on to win their 25th state title. The Bruins will be hot for revenge after dominating the quarterfinal only to lose on a penalty stroke.

River Hill at Glenelg, Oct. 12, 6 p.m.

In a rematch of last year’s Howard County championship, most of the key players return, including all of the goal scorers from the 5-2 Glenelg victory. Glenelg has dominated the series recently, but while the Gladiators won the state Class 2A title a year ago, River Hill was the state finalist in Class 3A.

Archbishop Spalding at Garrison Forest, Oct. 25, 4 p.m.

A lot could happen between now and this IAAM A Conference regular-season finale, but the date likely will be circled in red on both teams’ calendars. Last year, Garrison Forest went unbeaten through the conference season, including a 3-1 win over the Cavaliers, but Spallding stormed past the Grizzlies, 3-0, in the title game.
