David has slain Goliath.

OK, that's a little extreme ... but Lower Merion knocked off previously unbeaten Conestoga Monday night, 46-44, to force the first-ever Central League playoff tournament.

Greg Robbins and Harley Williamson scored 14 and 13 points, respectively, for the Aces (17-4, 14-2), who have won 12 in a row after losing uncharacteristically three of their first four games of the season. Jake Cohen was held to nine points as the Pioneers (20-1, 14-1) lost for the first time all year.

What does this mean?

Well, now the Central League will hold a four-team playoff tournament to determine its league champion. The first-round games will be held Thursday night at the sites of the higher seeds and the title game will be held Saturday night at Ridley High School.

At this moment, this is how the semifinal matchups shake out:

• No. 3 Penncrest (17-4, 12-4) at No. 2 Lower Merion (17-4, 14-2)
• No. 4 Upper Darby (13-6, 11-4) at No. 1 Conestoga (20-1, 14-1)
