McGinley birdied his opening two holes for a second time in four days, and then moved to five under through 11 holes before dropping a first shot at 12.
He then birdied the 15th for a third day but then for a second day running bogeyed the last when his ball came to rest under the lip of a greenside bunker in a round of 67 and a share of eighth spot on one-under par tally.
Frenchman Gregory Bourdy birdied his closing three holes to end a four-year winless drought. A 67 brought him to eight under par and a two shots win.
Damien McGrane had his best finish in 18 months with a last day 71 to finish tied sixth on two under par.
McGinley’s last top-10 was in Munich in June 2012 and just a fortnight after he shared sixth place at Celtic Manor.
“Like a school report when I was at school, this week was very good at times but other times I fell asleep,” said McGinley smiling.
“But as I’ve said since being Ryder Cup captain it is an important part of my duty to show that I can stay competitive so that will give me more opportunity to can play with the potential team players.
“I played with Ross Fisher this last round and he’s a former Ryder Cup player and that’s the kind of experience I want to be able to pick up over the next 13 months.”
David Higgins posted a level par 71 to finish at two over par while Gareth Maybin birdied three of his closing five holes in a score of 72 for a seven over par total.

This week was the first time Montgomerie had played in a standard European Senior Tour event after spending most of his time on the Champions Tour in the United States but rounds of 68, 68 and 70 saw him ease to victory.
