Both Blair and Sherwood overcame what may have been more physically talented opponents to win boys semifinal games last night in the sixth-annual IAABO tournament at Blair.

Behind crisp passing and aggressive defense, the host Blazers (6-0) built a 20-point second-half lead and continued to an 85-57 victory over McKinley (2-2).

Blair, enjoying its finest start in years, will meet Sherwood tonight at 7:30 in the championship.

Sherwood (4-2), playing with patience and shooting well from outside, surged back from an eight-point, fourth-quarter deficit to defeat Eastern, 81-77.

Blair showed its experience early, despite playing without injured starting center Teddy Romet.

McKinley used its fast break to move to a 15-8 lead, but Blair's Earl Boyd (17 points) scored off a fast break and converted a pair of free throws. Ray Fisher drove the lane to score and tie the game at 15.

But Blair built a 41-31 halftime lead and padded the margin to 56-36 with 4:36 left in the third period.

Blair's David Vanterpool had 20 points, 8 rebounds and 5 steals.

In the other semifinal, Eastern (2-3) squandered an eight-point lead in the fourth quarter.

Sherwood still trailed by 68-61 with less than five minutes left, but Mark Smith (game-high 29 points) and Matt Bradely (19 points) led a 20-9 charge.
