This was the Royals’ 13th win in a row since they last tasted defeat on September 9 at Sherborne Town.
Victory never looked in doubt in this game after the visitors got their noses in front after only three minutes, although they had to wait until the second half before they added further to their goal tally.
The sequence of play which brought the opening goal started with a corner on the right. After it was partially cleared by the home side it was crossed back into the danger area several more times before one of the crosses picked out Ryan Woodford and he headed the ball home from six yards out.
The visitors didn’t find the home side to be quite the push overs other sides had when they ran up big scorelines against them in previous weeks.
On ten minutes a quick break forwards by Lymington from midfield saw a low ball from the right find Toby Colmer but his attempt to fire off a shot was blocked before he could get it out of his feet.
On 23 minutes Jesse Rabin took a free kick from 25 yards out and forced keeper Steven Mowthorpe to dive to his right to push the shot around the post.
The home defence were able to block several Portchester chances before they troubled keeper Dale Hind. Lee Wort knocked the ball down to Harrison Brook, who tried to steer his shot home but a defender blocked it, and Wort and Jake Raine were denied in the same way.
Woodford went closer to finding the target on 33 minutes from a corner from the right but his effort from eight yards out hit the crossbar.
Richard Bakery tried his luck from wide on the right after spotting Mowthorpe off his line but the keeper gathered the shot comfortably.
At the other end in the closing moments of the first half Wort had a shot from the edge of the box tipped on to the crossbar by Hind, the keeper then made an acrobatic stop to block Brook’s shot with his legs while diving the wrong way and Archie Wilcox put his effort narrowly wide after driving forwards with the ball from midfield.
Lymington tried to force their way back into the game with a couple of early chances in the second half. Matt Grzybowski put his shot from the left side of the penalty area into the side netting and Mowthorpe had to block Harry Yates’ goal-bound effort.
However, any home hopes of a surprise result vanished on 53 minutes when the visitors doubled their advantage. Conor Bailey’s corner from the right was glanced into the net by Woodford from four yards out.
On 58 minutes another ball into the box from Bailey almost produced a goal when substitute Josh Benfield chested it down but couldn’t connect with the ball and Wort missed it as well as he tried to hook it towards goal.
Portchester’s third goal arrived on 65 minutes when Benfield’s low cross was deflected past the far post by a defender. The resulting corner was cleared as far as Jake Raine 25 yards out and he hit a low shot through the crowd of players in front of goal and into the back of the net.
The visitors went close to adding to their lead in the final ten minutes of the game. On 83 minutes Bailey had a shot charged down which rolled to Benfield, whose shot then hit a defender and rolled wide.
On 88 minutes a corner from the right appeared to be knocked several yards over the line twice but the linesman did not confirm that the ball had crossed the line and play continued.
The final chance came in injury time when Charlie Williamson pulled the ball back from the right to Benfield on the edge of the box but he put his shot over the bar.
