|LV= County Championship - Division One, Trent Bridge|
|Close of play, day two: Somerset 386, Nottinghamshire 303-5|
|Notts 6pts, Somerset 5pts|
Alex Hales scored the second century of his career and Stuart Broad starred with the ball as Nottinghamshire had the better of day two against Somerset.
England prospect Hales scored 130 not out and shared a stand of 101 with Adam Voges (57), while Steven Mullaney made 49 as Notts closed 83 behind on 303-5.
Somerset had earlier resumed day two on 341-5 but lost their last five wickets for 45 runs as Stuart Broad took 5-95.
Craig Kieswetter added 14 to his overnight total for a career-best 164.
Watching England selector Geoff Miller will have been impresed with the performances of Kieswetter, Hales and Broad but it was the latter who did the damage in an overcast morning session.
Broad, who was dropped for England's final one-day international with Sri Lanka last Saturday, toiled on day one with just the reward of two wickets.
But that all changed in the space of an hour as Broad got rid of Steve Kirby, Murali Kartik and Adam Dibble.
Andre Adams (4-93) took his Championship tally to 31 wickets this season , removing Kieswetter and Peter Trego, as Somerset fell 14 runs short of maximum batting points.
Notts stumbled to 36-2 at tea as Kirby (2-65) dismissed openers Riki Wessels and Neil Edwards and when Trego got rid of Samit Patel for 13, another first-innings collapse seemed on the cards.
But Hales and Voges put on 101 in 23 overs with the Australian scoring at a rapid pace.
Voges hit 11 boundaries in his 57 off 66 balls, before becoming a first Championship wicket for debutant Adam Dibble, who had began his spell with a wide.
Mullaney and Hales then added 87 for the fifth wicket but, just when another century partnership seemed on the cards, Mullaney was caught behind by Kieswetter off Kartik one shy of a half-century.
Hales, who was dropped twice before reaching three figures with difficult chances on 59 and 68, moved to his first Championship ton of the season with a four.
The 22-year-old was still there at the close unbeaten on 130, six short of his previous best of 136 against Hampshire last season.
POST MATCH REACTION
BBC Radio Nottingham's Dave Bracegirdle:
"Alex Hales' second championship century was worth the wait.
"Since reaching three figures for the first time against Hampshire last season he has been dismissed three times in the 90s and three times in the 80s, so to convert his sixth half-century of the summer was understandably a proud moment for the 22-year-old.
"Chairman of Selectors Geoff Miller was on the ground, ostensibly watching Stuart Broad collect a five-wicket haul but he, along with everyone else, will have left mightily impressed with the stylish Hales for whom a Lions call comes ever closer."
