Irish Premiership: Glentoran 0-1 Linfield
A second-half Matthew Tipton penalty saw Linfield beat Belfast rivals Glentoran and move two points ahead of Cliftonville at the top of the table.
Tipton fired home from the spot in the 50th minute after Jordan Stewart had fouled Sean Ward inside the area.
Linfield created the better chances and Andy Waterworth, Philip Lowry and Ivan Sproule went close in the first half.
Jonny Tuffey saved well from Curtis Allen and Waterworth was twice denied by Elliott Morris after the break.
After the match Blues manager David Jeffrey, who last week announced that he would be leaving his position at the end of the season, said he was pleased to win on his last visit to the Oval to face Glentoran.
"I've taken a few insults here over the years so it was good to get the victory - it was more about the result than the performance tonight.
"Having said that, we should have won by three or four and made it easier for ourselves, but we showed great determination, concentration and mettle."
Glentoran made six changes from the side which started last week's 2-1 defeat by Ards and included teenage midfielder Kym Nelson for his debut.
In wet and windy conditions and playing with the wind in their favour in the first half, Linfield always looked in control as the Glens' poor home record this season continued.
Callum Birney headed over the bar for the home side but soon after, Morris was forced to tip away a Jamie Mulgrew cross as Tipton prepared to head into the net.
Waterworth shot into the sidenetting when a pass to Tipton looked to be the better option and then Morris was called into action again to deny Sproule's backpost header from a Billy Joe Burns right-wing cross.
Ex-Northern Ireland international Sproule forced Morris into another save with a well-struck effort and when the ball deflected off the winger, Jay Magee was on hand to clear off the line.
Lowry's right-foot drive clipped the bar, before Allen squandered the Glens' best goalscoring chance of the game against his former club.
The striker was denied by Tuffey, who then managed to claw the loose ball away as Allen was about to pounce and fire in the rebound.
Tipton's spot-kick nudged the visitors ahead, but the striker was perhaps fortunate to escape with just a yellow card for a bad challenge on Allen.
Morris stopped Waterworth's drive with his legs and also made a fine save from the former Glentoran forward's close-range effort.
