County Championship: Kellaway’s best puts Glamorgan on top v Kent
Resuming on 389-7 with Kellaway on 91 and the battle for bonus points the other immediate concern, the Chepstow youngster was happy to take his time over reaching three figures, achieved with a stylish cover drive for three off Kashif Ali.
Partner Andy Gorvin was dropped behind on 14 off Kashif but put together a quietly efficient stand of 108 with Kellaway as Kent suffered in the sun, collecting just two bowling points to the visitors’ four with the bat.
Gorvin eventually holed out to deep square off perspiring leg-spinner Matt Parkinson for a solid 47 off 99 balls.
Parkinson bowled James Harris for 12 as he looked to add quick runs after lunch, but Kellaway struck him for three successive sixes and a four in a spectacular burst of hitting before Sam Northeast called them in.
Kellaway faced 228 balls, striking 18 fours in addition to those maximums over mid-wicket, having hit a maiden first-class 50 only two matches ago.
Kent, under scoreboard pressure, then lost five wickets for just 23 inside 15 overs, after the returning Harris struck with his second ball of the season, having Harry Finch lbw before forcing Ben Compton to lob a catch to gully.
Van der Gugten had Kent captain Daniel Bell-Drummond, off the back of a double hundred, in all sorts of trouble before he edged to slip.
In a hostile nine-over spell, the Netherlands international then had Tawanda Muyeye and debutant Ekansh Singh caught at short-leg as both lobbed up catches, before Jack Leaning and Benjamin steadied the ship in a stand of 81.
Leaning had problems against Asitha Fernando, reaching 37 before the Sri Lankan won an lbw verdict, and Harris quickly forced Grant Stewart to play on.
Benjamin, the wicketkeeper recruited from Warwickshire, was lucky to survive a few moments against the seam of Zain Ul Hassan on his way to 50 off 83 balls.
Andy Gorvin had Matt Parkinson well caught behind off the inside edge for 13 though George Garrett survived the closing overs alongside Benjamin.
