NSW spinner Steve O’Keefe mopped up the tail as Tasmania made a first innings 354 in the Sheffield Shield match at Bellerive.

O’Keefe will begin the second innings on a hat-trick after finishing off the Tigers with consecutive balls, removing Ben Hilfenhaus and Sam Rainbird for ducks.

The left-arm orthodox tweaker finished with 4-74 after taking all four wickets to fall on Saturday morning, when the home side resumed at 6-299.

O’Keefe entered the match as the Shield’s third leading wicket-taker and his haul takes his tally to 20.

The 28-year-old trapped Evan Gulbis (23) in front at 7-340 after the Tigers allrounder had put on 57 with Luke Butterworth (41no).

O’Keefe then had Xavier Doherty (10) caught at cover chasing quick runs at 8-353 before knocking over Hilfenhaus and Rainbird.

Blues seamers Sean Abbott (2-71) and Gurinder Sandhu (2-82) each bagged doubles.

Tasmania’s total was largely thanks to a 143-run partnership between Ben Dunk (89) and Tim Paine (78) on Friday while Butterworth’s innings, with six boundaries, helped them beyond 350.
