1 - First-class innings of 200-plus balls since 2008 coming at a strike rate lower than Hashim Amla's 13.30 during his unbeaten 37 off 278 balls against Hampshire on Wednesday. Amla himself was responsible for a better effort in this period when he scored 25 off 244 balls, striking at a mere 10.24 against India in 2015.

19.24 - Amla's strike rate against Hampshire, the second-lowest by any player in a first-class match after facing 300-plus balls, in the last 15 years. Naeem Islam jnr struck at 19.20 against Rajshahi Division in the National Cricket League 2015 match, where he aggregated 63 runs from 328 balls. Amla was Surrey's top contributor in the first innings as well, scoring 29 off 65 balls.

1.16 - Run rate of Surrey's second innings against Hampshire, scoring 122 for 8 in 104.5 overs. This is now the second-lowest run rate in a first-class team innings of 100-plus overs since 2000. South Africa's 0.99 against India in 2015 stands on top as they scored 143 in 143.1 overs during an unsuccessful attempt to save a Test match in Delhi.

0.72 - Run rate of the fourth-wicket partnership between Amla and Ryan Patel, the fourth-slowest partnership of 25-plus overs in first-class cricket since 2010. Amla and Patel added 21 runs in 28.5 overs, during which Amla scored only two runs. Amla's partnership with AB de Villiers against India in 2015 stands third in this list as they scored at 0.64 during their stand of 27 from 42.1 overs.

63 - Balls Amla took to score his first run on the fourth day. He got off the mark on the fourth ball (and the last) he faced on the third day, and his second run had not come until the 67th ball of his innings. Amla had three streaks of 35 and more consecutive dot balls on Wednesday.

0.40 - Economy rate of Keith Barker during his figures of 22-17-9-3 in Surrey's second innings, the most economical bowling effort in a first-class innings since 2000 (minimum 20 overs). Amla alone scored seven runs off 84 balls he faced from Barker who had conceded only two runs in 48 balls he bowled to the rest of the Surrey batters.
