The two-time Olympic champion set the previous 100-butterfly record of 51.93 in the 25-meter pool Wednesday at Imperia, Italy,

Saturday, Pankratov clocked 23.35 in the 50-meter butterfly.

Pankratov established a short-course 200-butterfly record of 1 minute, 52.64 seconds last Saturday at Gelsenkirchen, Germany.

Pankratov is the first person to hold three short-course and two long course world records.
