2018 National Spelling Bee (8:30 p.m., ESPN) — We get the final round of the 91st Annual Scripps National Spelling Bee from Washington, D.C. Part 1 airs 10 a.m.-2 p.m. on ESPN2, but the second part airs in prime time, starting at 8:30 p.m. on ESPN's main channel. This is always surprisingly riveting — and once again we have had some local kids to root for, including Rahul Sachdev, a seventh-grader at Carnage Middle School in Raleigh, and Hanna Closs, a ninth-grader at Northern High School in Durham. There are lots more, and they've been competing all week. In all, there have been 20 spellers representing North Carolina this year, up from 14 last year. Other area students among the 519 who competed in the National Bee this year include Akshar Yeccherla of Cary and Cameron Glogower of Clayton.
