William Mortlock (18 July 1832 at Kennington, London – 23 January 1884 at Lambeth, London) was an English professional cricketer who played first-class cricket from 1851 to 1870. His brother Thomas was a first-class umpire.
A right-handed batsman and slow underarm bowler who played for Surrey County Cricket Club, Mortlock made 191 known appearances in first-class matches.[1] He represented the Players in the Gentlemen v Players series.
Mortlock sometimes opened the innings and he scored a total of 5528 runs at an average of 18.73 with a highest score of 106. He made three career centuries. A versatile fielder, renowned as a longstop who seldom allowed a bye, he took 85 catches.[2] [3] He took 147 wickets with underarm bowling at 18.02 with a best analysis of 7/42 and he twice claimed ten wickets in a match. Haygarth considered his lob bowling 'rubbish'. Mortlock participated in the first cricket tour of Australia in 1861-2. The team travelled to Australia on the SS Great Britain.[4] It was on this tour that Mortlock gained the nickname 'Old Stonewall' for his stubborn defensive batting and longstopping.[3]
Mortlock died at his home in Acre Lane, Brixton, on 23 January 1884, after an illness that had incapacitated him for two years. He was buried at West Norwood Cemetery.[3]
