Linfield 5-0 Donegal Celtic
Philip Lowry hit four goals in this Windsor Park rout to make the champions the early Carling Premiership leaders.
The midfielder headed in the opener from Nathan Hanley's free-kick before doubling the lead with a volley.
Hanley was red-carded just before the break after a challenge on Paul McVeigh but the Blues remained in control.
Lowry clinched his treble with a back-post finish and his close-range header made it four before David Armstrong blasted in with eight minutes left.
