A second-half double from Jed Wallace helped Portsmouth cruise to a 3-1 win over League One Yeovil at Huish Park.The 20-year-old broke the deadlock with a fine left-footed finish and then found the bottom corner with his right. Seconds later Craig Westcarr lifted in the third only for Yeovil's Nathan Ralph to grab the goal of the night. It took until the 34th minute for either goalkeeper to be tested, the recalled Kieffer Moore working Paul Jones and then heading wide when unmarked just before the break. Moore's guilt-edged miss would prove costly when Wallace scored with Portsmouth's first real chance of note in the 55th minute. The midfielder played a one-two with Westcarr on the edge of the box and then fired across goal and into the bottom corner. Sam Foley almost found an instant response but Pompey's place in the next round was sealed with 18 minutes left when Wallace composed himself and arrowed an effort across goal. Two minutes later Westcarr got in on the act, cutely lobbing Chris Weale, before Ralph thundered home a consolation via the underside of the crossbar in the 83rd minute.
