Nick Compton scored an unbeaten 139 to put his England problems to one side and help Somerset reach 336-5 at stumps on day one of their Division One fixture with Durham at Taunton.
Compton's place in the England side for the upcoming Ashes series is under threat after a series of underwhelming performances but he took advantage of the opportunity to impress the selectors.
The 29-year-old struggled for runs in the opening session of the day as he managed just 23 off 87 deliveries before lunch.
But Compton cut loose after the break and took advantage of a dropped catch from Paul Collingwood when he was on 53 as he took the advice of national coach Andy Flower to regain his touch on the county circuit.
Compton and Marcus Trescothick had put on 47 when the former England opener drove at a wide ball from Graham Onions (2-43) and was caught by Scott Borthwick at second slip after cruising to 36.
The home side went into lunch on 82-1 and put on another 50 runs before Arul Suppiah (36) was clean bowled by Onions as the seamer attempted to remind the England selectors of his abilities.
Dean Elgar also got a start only to lose his wicket in the 30s, Will Smith enticing him into a wild shot that saw him bowled for 33.
James Hildreth was at the crease to see Compton reach his century, with a misfield by Mark Stoneman at mid-off allowing the ball to go through to the boundary.
Hildreth progressed to 32 when he fell lbw to young off-spinner Ryan Buckley as he played across a full ball, with Somerset in danger of failing to capitalise on typically favourable batting conditions at Taunton.
Alex Barrow (25) appeared settled but he then fell victim to the second new ball as Mark Wood cleaned him out.
Instead it was left to Compton to show his team-mates the way, with Peter Trego (14 not out) offering support.
