Earmarked for a long time as a star-in-waiting, Will Jacks first shot to mainstream attention with a 25-ball hundred in a T10 game in a pre-season game against Lancashire in Dubai. After a ton against India in an Under-19 Test in the 2017 summer, he went to the Under-19 World Cup in 2018 as vice-captain, where he hit 102 against Canada but largely struggled elsewhere.

Jacks was one of a clutch of Surrey young guns who advanced their reputation during their Championship-winning season in 2018. Jacks made his debut in all three formats, at 19, and made a significant impression with a maiden county century against Gloucestershire at The Oval in the One-Day Cup, including four sixes in his 121 off 100 balls.

A tall, clean-hitting batsman who also bowls useful offspin, Jacks was widely expected to have a breakout summer in 2019 but aside from a superb maiden first-class hundred at Beckenham, he flattered to deceive somewhat, averaging in the 20s in all formats; a strike rate above 150 in the Blast reflected his aggressive game, but he was not as prolific as hoped.
