Lassodie duly entered the 1887–88 Scottish Cup and reached the third round, albeit without winning a match.

[4] However, the club recovered quickly, as it was drawn to meet Cowdenbeath in the second round of the national competition a fortnight later.

The 1888–89 final saw both sides reduced to ten men, as right-forward Jock Wilkie of Lassodie and Law of Cowdenbeath "deliberately squared at each other" and "got into grips", thus being ordered off.

[8] Wilkie had "come under the censure of the referee" in an East of Scotland Consolation Cup tie with Dunfermline Athletic, which ended 5–5, three months earlier;[9] he did at least have the consolation of getting his county cap, along with team-mates Murphy (half-back) and Masterson (left-forward), in the Fifeshire match against Linlithgowshire that season, and was named as Fife's best player.

[14] En route to the 1891–92 triumph, Lassodie got past Cowdenbeath for the only time competitive football, before beating Adventurers of Edinburgh 3–2 in the final.

[15] The effective end of the club came in August 1894, when it changed its name to Loch Rangers and moved four miles south to Kingseat.

The Rangers suffered two heavy defeats in major competition in that season; 11–0 at Broxburn Shamrock in the Scottish Cup[17] and 6–1 to Cowdenbeath in the first round of the East of Scotland Shield.
