Third-ranked McKinley squandered most of its 26-point lead but choked off surging Springard, 91-83, in an Interhigh League battle for first place yesterday at McKinley.

The Trainers raised their league mark to 8-0, and 16-1 overall. The 12th-ranked Green Wave fell to 8-2 in the lague and 13-5 overall.

McKinley jumped on a Green Wave zone defense for baskets in bunches, streaking ahead 41-25 at the half.

The Trainers took a commanding 64-42 advantage after three periods, connecting on nine of 12 attempts from the floor in a productive third quarter.

With a seemingly insurmountable advantage, McKinly coach Walter Kennedy filled the floor with substitutes. Spingarn, usually strong in the final quarter, took advantage of Kennedy's generosity and began to peck away.

"I knew I'd lose something when I subbed," said Kennedy. "But these guys have sat on the bench all year and this was a good time for them to gain game experience without pressure."

With Joe Brawner scoring from the outside and teammates Diego McCoy and Reggie Nance scrapping for garbage baskets underneath, Springarn sliced McKinley's advantage to 15, 12, eight, and finally six points wiht 30 seconds remaining.

By the time Kennedy has rushed his starters back to stem the Green Wave comeback, Brawner's steal and subsequent layup had narrowed the deficit to, 87-83 with 20 seconds remaining.

McKinley's Jarvis Smith then sank two free throws for a six point edge with 12 seconds left, assuring McKinley's 16th straight victory.

"The guys don't quit," said Green Wave coach John Wood. "But when you get behind to a good club by that much, it's hard to come back."
