[3] On November 24, 1919, he first met future champion Pete Herman, fighting him to an eight-round newspaper decision at the Grand Theater in Trenton, New Jersey.

[3] He first fought future champion Abe Goldstein on July 6, 1920, in New Jersey in a twelve-round, no-decision bout, where several newspapers gave him a decided edge.

In the second round, Buff shot a hard right that landed solidly on Goldstein's chin causing the knockout.

[10][11] On April 16, 1921, he defeated Young Zulu Kid, in an American Flyweight Championship bout in a fifteen-round points decision at the Broadway Arena in Brooklyn.

[12] On May 2, 1921, Buff defended his American Flyweight Championship against Eddie O'Dowd at Madison Square Garden in a twelve-round unanimous decision.

In the second round, fighting with both hands and greater speed, Buff put O'Dowd on the mat for the first time.

In the last six rounds, O'Dowd took considerable punishment, and appeared to have received a broken nose in the eighth, which greatly affected his chances.

Somehow in the eleventh round, O'Dowd landed three solid right hooks to Buff's jaw, but was unable to bring him to the mat.

[2][5] Buff had a noteworthy defense of the World Bantamweight Title at Madison Square Garden against Jackie Sharkey on November 10, 1921, in a fifteen-round points decision.

[3] On July 10, 1922, Buff lost the World Bantamweight Championship to Joe Lynch at the Velodrome in New York in a fourteenth-round TKO.

A few ringside felt that facing Lynch so soon after taking the bantamweight championship was poor matchmaking on the part of Buff's handlers.

[16][17] Buff officially lost the American Flyweight Championship on September 14, 1922, in an eleventh-round technical knockout against the great Filipino boxer Pancho Villa at Ebbets Field in New York City.

Lisky died after a long illness on January 14, 1955, at the Veterans Administration Hospital in East Orange, New Jersey.
