The top four seeds all cruised to quarterfinal wins in the IAAM C-Conference soccer playoffs on Tuesday.

Top seeds Garrison Forest and Key both posted 4-0 wins, while St. Timothy's ousted Oldfields, 4-1, and Annapolis Area Christian eliminated Mount Carmel, 5-1.

That means the semi-final round is set for Thursday, with a pair on intriguing match-ups. AACS will visit Key and St. Tim's will visit Garrison, with those two winners going on to a spot in Sunday's championship game at Glenelg Country at 10:30.

Here is a quick look at Tuesday's quarter-finals.

THURSDAY SEMI-FINALS

#2R AACS @ #1G Key
The Battle of Annapolis pits last year's championship game teams. In 2006, these two met for the C title at Friends, with the Eagles edging the Obezags, 1-0. During the regular season this year, the Eagles once again had the upper hand, with a 2-0 win at Key back in mid-October. Coach Chris Rixham thinks his Key team has improved since then, and says they are ready for the challenge. Eagle Coach Paul Brophy wants to return to the finals for a shot at a repeat. Only one Annapolis area team will make this year's finals - which one?

#2G St. Tmothy's @ #1R Garrison Forest
The other semi-final makes for another intriguing match. Coach Casey Scoeberlein brings in a Garrison Forest team that is competing in outdoor soccer for the first time. Most brand new teams would be happy to get a few wins, but the Grizzlies put up the league's best record and have a shot at winning it all. On the St. Tim's side, it is the third year of competition, and the team had gone winless in both the first two seasons. Coach Glenn Quinn has turned the program around, with an impressive 8-2-2 record. Garrison won the lone season meeting, 2-1 at STS, and the Grizzlies have the home field today. Which of these "new programs" will advance to the finals?
