Hashim Amla continued to impress at Hampshire after his third fifty in as many matches, while Aiden Markram has yet to score.
Amla scored a fighting 69 off 122 balls (11 fours) in Hampshire’s 223 in reply to Notts’ first innings of 302.
He may need to redouble his efforts, though, if Hampshire are to get anything out of this as Notts moved on to 136 without loss to take a lead of 215.
At the opposite end of the spectrum, Markram has had a brutal introduction to County cricket, registering another duck in another appalling display by Durham.
He started his short-term stay with the northern team with a pair, and then spent four days watching the rain come down in Northamptonshire. In this round, he faced just four balls as Durham struggled to 14-4 in reply to Leicestershire’s 440.
Colin Ackermann contributed 36 to that total. Durham ended the day on 147-7, so Markram may get another go on Sunday.
Dane Vilas is another Saffa in form after he ended Saturday on 83 in Lancashire’s innings of 217-2, chasing Somerset’s first offering of 427.
Vilas, in his second year of a Kolpak deal, struck seven fours and two sixes in his partnership of 169 with England opener Keaton Jennings (91), the son of Ray Jennings.
Derbyshire are on the brink of defeat, despite the efforts of the two Saffas, Hardus Viljoen and Duanne Olivier.
Olivier hit an unbeaten 40, batting at 10 in Derbyshire’s first innings of 318, and then took four wickets, to go with Viljoen’s two, as Warwicks replied with 439. Viljoen then valiantly tried to build a target with a quickfire 44 off 54 balls, but his team collapsed to 209. Warwicks were left with 89 to win.
