The Saffa fireforce continued blazing away in the County Championship, with Duanne Olivier sending a reminder to the Proteas selectors by taking 10 wickets for Derbyshire.

After bowling Durham out for 96 in the first innings, with Olivier taking 5-20, the second was a much more testing affair as Durham ran up 376. Olivier grabbed 5-105 off a monumental 40 overs, at an economy rate of 2.62.

Derbys were undermined by the fact that they gave away 81 in extras: 34 byes, 23 leg byes, 22 off no-balls and two wides.

Hardus Viljoen provided some support for Olivier, with five wickets in the match. At the close, though, Derbys were 69-4, needing 199 to win.

In Manchester, the CSA Sunfoil Player of the Year, off-spinner Simon Harmer, was on a roll with his pace partner Jamie Porter as they took nine wickets between them to dismiss Lancashire for 105 and set up a victory target of the same.

Harmer, who plays for the Warriors, snapped up 4-34 to go with his first-innings 3-35. Porter took 5-30 in the second innings, along with his earlier 2-68.

Those two ended top of the bowling list last year, with Porter (75) pipping Harmer by three wickets.

Dale Steyn, who took 2-91 off 26 overs in Surrey’s first innings, was not called to bowl again after Hampshire were asked to follow on and fell short by 58 runs. Steyn has been called up by the Proteas for the two-Test tour of Sri Lanka in July.

Morne Morkel, who signed a Kolpak agreement with Surrey after retiring from international cricket, finished with 5-70 over the two innings.

Rory Kleinveldt made an impact for Northants against Leicestershire, taking 4-51 off 17 overs in the first innings. But the batting slipped and Leicestershire cruised home by six wickets, with Kleinveldt adding just one more wicket for a match total of 5-90.
