The game's in question are our goalless draw with Dundee United at the start of the season, a similar game against Motherwell a few weeks ago and a 2-0 defeat to them at Fir Park in January. The only bright spot is a League Cup win over Kilmarnock back in September, where we scored twice.
Last season, Mr McDonald did just one Saints game - and it was away at Falkirk. Despite being in terrible form, we won 2-1 and the Bairns had Jackie McNamara sent off for a shocking challenge on Jim Hamilton.
This official's other Falkirk games last season had mixed results for the Bairns. They won a Scottish Cup semi-final against Dunfermline and an earlier game against Hearts, in which each side finished with 10 men. However, they also lost to Dundee United and Rangers.
As Mr McDonald has a fairly lengthy track record with both Saints and Falkirk, there's no point going over old ground again so here's a link to the article from last season's game between the two sides: http://www.stmirren-mad.co.uk/roll/ed16/know_the_ref__falkirk_away_420261/index.shtml
This season, Mr McDonald is averaging less than a red card every five games - and he hasn't sent anyone off since the controversial Old Firm game at the end of February.
