It's a stroke very reminiscent of the one played by Geoff Boycott to reach his 100th hundred against Australia in 1977.
Btw, Pennington didn't manage a hat-trick (see 11:27 entry) after dismissing Sam Northeast and Kiran Carlson with successive deliveries.
Kent 120-7 v Essex 573

Kent 105-6 v Essex 573
The good news for Kent was that Sam Billings was fit to bat after being off the field injured yesterday.
