Senior guard Lamarr Mitchell was fouled and went to the line with seven seconds to play and the score tied between No. 12 City and No. 6 Lake Clifton.
He swished both free throws and the visiting Knights defense held firm to seal a 43-41 win over their Baltimore City rivals.
Fellow senior DeJuan Johnson scored a game-high 15 points, and Mitchell scored 10 of his 14 points in the second half as City (9-1) improves to 3-1 in league play. Lake Clifton (8-3, 2-2) dropped its second straight league game.
"It was tough coming out [down] 7-0, and I thought we stayed poise," City coach Daryl Wade said. "I didn't like the way we were playing offense early, [but] we found a little rhythm — DeJuan found fire and hit some big shots, and Lamarr found some rhythm and, defensively, Nick [Tates] defended the ball, so it was a good team effort."
The Lakers, who were without senior guard Shauntaze Drake because of a sore ankle, got a team-high 14 points from Rasheed Brown.
The Lakers' biggest lead was their 7-0 run to open the game and they took a 30-24 advantage at the half. But the second half was played at a slower pace — the Lakers held the ball the first three minutes of the third quarter with the Knights staying in their zone defense. The visitors won the quarter by a 9-2 count as Mitchell's jumper with 20 seconds left gave them their first lead at 33-32.
With the game tight through the fourth quarter, the Lakers got a three-point play from Alphonso Barney (10 points) with 2:16 to play for a 40-37 advantage. The Knights answered with a driving layup by Tates, a follow from Diego Thompson and consecutive defensive stops to take a 41-40 lead with 22 seconds left to play. Barney, fouled trying to put back a rebound on the Lakers next possession, hit one of two free throws to tie it with 12 seconds left before Mitchell was fouled going to the basket. After his two makes, the Knights had a successful final stand on defense with Barney's 3-point try from long range hitting the back rim.
"We're learning how to play through adversity and it starts on defense," Johnson said. "We had a slow start and Coach Wade said just play 'D,' play 'D.'"

The Patriots (8-5) led 27-25 at the half, but used an 8-0 run to open the second half to push the lead to double digits. A 7-2 run to begin the final quarter was too much for the Mustangs to overcome.
