Tip-off for Tuesday's showdown between the top two boys' basketball teams in Division I, city rivals Manchester Central and visiting Trinity, has been moved back a half-hour, from 6:30 to 7 p.m.

Both teams enter the night with 15-1 records in NHIAA play and one more regular-season game to play after Tuesday.

The Little Green and the Pioneers have met once this season, Central prevailing in the opening round of the Queen City Invitational, 64-50, on the day after Christmas. Junior point guard had a game-high 18 points to lead the Green.

Central is coming off its first loss of the season, 70-62 to Nashua South last Tuesday. The Little Green wrap up the regular season Friday at Bedford, which is a relatively modest 10-6 but has won its last four games and seven of its last eight.

Trinity has won five straight since its only NHIAA defeat, a 60-56 loss at Merrimack on Feb. 12. The Pioneers play their last regular-season game Friday at Timberlane Regional in Plaistow.
