Glamorgan 229 (Kellaway 59, Pretorious 3-50) and 285 for 8 (Dickson 76, Tribe 52, Hadley 50*, Pretorius 4-74) beat Somerset 354 (Abell 86, Thomas 71, Norton 3-75) and 157 (Abell 71, Norton 4-61) by two wickets
An improbable century partnership from Sean Dickson and nightwatcher Ryan Hadley helped Glamorgan pull off a nail-biting two-wicket win despite Somerset's late comeback.
Glamorgan followed up their win against Hampshire, thereby bettering already their one victory the last time they were in Division One over two decades ago. Former Somerset batter Dickson scored 76 to take the sting out of the bowlers' onslaught, which had reduced Glamorgan from 81 for 0 to 134 for 5 late on day three.
Hadley's monumental effort spanned 231 balls for his maiden first-class half-century, brought up with a straight drive to win the game. He came into this game with an average of 5.77 and high score of 15 not out, but played a key role as Glamorgan started day four with 143 needed and five wickets in hand.
Somerset would be made to rue a number of events in the game which led to them squandering a 125-run first-innings lead despite a late fightback with the ball. James Rew's opening efforts combining for just four runs, three dropped catches on the final day and the use of Jack Leach, who bowled just one over of the fourth innings, all potentially points of blame in a second consecutive defeat.
Dickson and Hadley resumed on day four, fully aware of the difficulties ahead of them given the metronomic spells from the four-strong seam attack late on day three to swing the game in Somerset's favour.
Hadley's 2 from 26 gradually became a career-best for balls faced, which previously sat at just 54 when playing a nightwatcher role in the Sheffield Shield (he had faced 250 balls for his entire first-class career before this game), then by lunch had crept over his best score. Glamorgan's usual No. 11 had two reprieves in the form of dropped catches, one before lunch and one after, both by Craig Overton at second slip to ensure a wicketless first session.
Just 62 runs came from 30 overs before lunch, which was timely for Glamorgan. Leach's sole over, which started at 12.56pm (the 86th over of the innings), saw Hadley bamboozled but somehow survive.
Dickson recorded a third half-century in as many games by flicking a boundary through midwicket against his former side, relishing his newfound role at No. 6.
Hadley crept along watchfully only to show flashes of ability, as when on 22 from 157 balls he drove Jake Ball handsomely through the covers.
Overton found Hadley particularly frustrating, evidenced by frequent sightings of hands on his head, his hips and his knees hurled over in his follow through; the Glamorgan fast bowler escaped when fending a bouncer short of square leg, only for the following ball to ricochet off the ducking Hadley's back to the boundary for second occasion of four runs coming from evasive action.
A bizarre scenario also saw Somerset celebrating as umpire Paul Pollard looked to give Hadley out lbw, only for him to be adjusting his hat - Somerset therefore denied the breakthrough.
The eventual rays of hope came too little too late for Somerset. Dickson was trapped in front with 35 needed, and only seven had been added when Chris Cooke went the same way. Timm van der Gugten also fell lbw with 13 needed. But Mason Crane proved a reliable partner for the ever-present Hadley, whose increasing comfort was on display as he straight-drove Pretorius for four and went on to hit the winning runs.
