William Cosgrove (1855 – 1927) was a Scottish professional golfer who played in the late 19th century. Cosgrove had one top-10 finish in The Open Championship. His best performance was a third place tie in the 1877 Open Championship.
Cosgrove was born at Inveresk, Scotland, in 1855. He was the son of Alexander Cosgrove, a maker of golf clubs, and his wife Janet Nelson. The family resided in James Place, Millhill, Inveresk. He married Mary Jane Quin in 1878 and was employed as a maker of golf balls. His cousin, Ned Cosgrove, also became a professional golfer.[1]
The 1877 Open Championship was the 17th Open Championship, held 6 April at Musselburgh Links, Musselburgh, East Lothian, Scotland. Jamie Anderson won the Championship, by two strokes from runner-up Bob Pringle. Cosgrove scored rounds of 41-39-44-40=164, finishing tied for third, and won a useful £2 in prize money.[2]
Cosgrove teed it up again in the 1878 Open Championship held 4 October at Prestwick Golf Club in Prestwick, South Ayrshire, Scotland. Jamie Anderson won the Championship for the second successive year, by two strokes from runner-up Bob Kirk. Cosgrove had rounds of 55-56-55=166 and finished in a tie for sixth place with Willie Park, Sr.
Davie Strath and Bob Ferguson played together but Strath had a disappointing 45 in the first round which left him well behind the leaders. Ferguson began in disappointing fashion but managed to salvage a 40. William Brown led on 39 with Ferguson and Jamie Anderson on 40. After two rounds, three players were level on 80: Brown, Ferguson and Cosgrove with Anderson and Bob Pringle only two behind. Strath was five behind on 85.
Anderson carded a 37 in the third round while Ferguson could muster only a 40 and Davie Strath scored 38. Anderson now led on 119 with Ferguson on 120, Ferguson on 122 and Strath on 123. In the final round Strath took a horrendous 9 at the second to drop out of contention. Ferguson also had a disappointing last round and Anderson's 41 was enough to give him the Championship.
Cosgrove died in 1927 at Newington, Edinburgh, Scotland.
