Carroll avenged an earlier loss to Mackin with an 87-78 victory last night to win the Shaughnessy Tournament at De Matha.
The Lions (24-5) will meet Inter-high runner-up McKinley Sunday at 1 p.m. in the preliminary to the Dunbar-De Matha city title game at Cole Field House.
The victory came in a tournament that Carroll Coach Jack Bruen feels is unnecessary and "like being sentenced to the salt mines in Siberia."
But Mackin gave the Lions a scare: briefly.
Mackin's mesh of agressive defense, deadly outside shooting and fast break offense -- the ingredients that carried the Trojans to 24-5 record -- lasted one quarter.
Those first eight minutes resembled a repeat of Mackin's 67-60 victory over Carroll, during which the Trojans turned on a 22-6 first-quarter blitz.
It seemed as if the Lions were looking back, as Mackin's Jonny Dawkins scored 10 points before five minutes had elapsed.
Bruen called a timeout. He told his team to be patient and look for an inside shot, and the Lions charged back. They trailed by only one at the end of the quarter.
Carroll's Chester Wood suddenly started making short jumpers and layups. Guard Jeff Baxter, held to just two points in the first quarter, ended up scoring 22 more in the game to match Wood for team-high honors.
The key to the victory for Carroll was Bruen's defensive change in the third quarter. He pulled Dwayne Hayes off Dawkins (16 first-half points) and placed Joe Howard, on the hot-shooting guard.
Howard's defensive play inspired the Lions, who held Mackin to just four points in the quarter. Dawkins could shake Howard for only one third-quarter basket as he and his teammates watched Carroll's four-point halftime lead increase to 16.
Dawkins did get away in the other three quarters. The 6-foot-2 guard finished with a game-high 31 points.
