Harris' development has continued apace since then, and he was rewarded by a call-up to the England Lions team which took on Australia last summer.
And in January, he spent 10 days in India at Dennis Lillee's bowling academy as one of four England development players under the wing of the Australia Test legend.
"One of the goals I set this season was to get 100 before was 20 which happens on 16 May so I've done that with some time to spare," said Harris.
"More importantly, I'm very pleased for the lads as it was a very good win and a very good performance in the end.
"I think we only won a couple of games last season and to win two already in April is a very good achievement.
"We're playing some exciting cricket at the moment."
