Lewis is a highly-rated young wicketkeeper and right-handed batsman.
A product of Hampshire's highly successful youth system, he first started attracted attention as part of the County's Under 17 ECB 50-Over Cup winning side in 2011.
The following season, he was awarded the Fielder of the Year Award at the Hampshire Cricket Board’s end of season presentation ceremony.
A number of impressive performances for the Hampshire Academy in 2013 - including an unbeaten 96 against a strong St Cross Symondians side in the Southern Electric Premier League - saw McManus gain a call-up to England Under 19s for a tri-series against Bangladesh and Pakistan's respective Under 19s.
He finished the summer having scored 216 runs at an average of 36 in the Second XI Championship (including a high-score of 105) and was once again selected for an England Under 19 tri-series against Pakistan and UAE in the UAE in December 2013 and the Under 19 World Cup in February 2014.
McManus impressed with both the bat and behind the stumps during his two first-team appearances for Hampshire in 2015. Under immense pressure from a rampant Durham bowling attack, the 20-year old showed experience and resilience beyond his years, to hit 53 not out to see Hants through to what proved to be a vital draw at the Ageas Bowl.
Awarded a new two-year contract at the end of the 2015 season, Lewis took over the gloves from Adam Wheater whilst contributing impressive performances with the bat.
McManus recorded his highest first-class score with an unbeaten 132 against Surrey at the Ageas Bowl in July and surpassed fifty on three other occasions during his breakthrough season as wicketkeeper.
McManus signed a three-year contract extension ahead of the 2017 season. Lewis' 2017 season however, was unfortunately cut short due to a broken finger. Although in the time that he was fit to play before his injury during that season, the wicketkeeper-batsman scored his maiden T20 half-century in July as Hampshire began their campaign with a comfortable win over Glamorgan in July.
