Nottinghamshire held on for a draw against Somerset on the final day at Trent Bridge.
The home side resumed on the fourth morning on 47-0 in their second innings needing another 236 to make the Somerset bat again.
Despite being without pace spearhead Steve Kirby due to a hamstring strain, Somerset were on course for victory when Nottinghamshire were reduced to 85-3 before lunch.
Seam bowler Peter Trego (2-62) struck twice, including the scalp of England all-rounder Samit Patel lbw for 11.
But a rain delay wiped out the afternoon session and, after spinner George Dockrell (1-25) bowled Michael Lumb (23) through the gate, fifth-wicket pair James Taylor (38no) and Chris Read (33no) saw Nottinghamshire to safety with an stand of 60. They had reached 169-4 when a draw was agreed just after 5pm.
Nick Compton completed his third double-century inside a calendar year and Arul Suppiah and James Hildreth also hit hundreds as Somerset dominated Nottinghamshire on day three at Trent Bridge.
After rain had severely limited play on the first two days, the visitors racked up a commanding 445-2 declared after resuming on 78-1 in reply to Notts' below par 162.
Compton was the driving force behind that mammoth total with an unbeaten 204 from 323 balls - his second ton coming in just 81 balls - and contained 15 fours and three sixes.
Compton - grandson of former England legend Denis - put on 216 for the second wicket with Suppiah (124) and then joined forces with Hildreth (102 not out) to add another unbeaten 217 for the third.
The right-hander continued the remarkable run of form that has already seen him score 133 against Warwickshire, 99 against Middlesex and 236 against Cardiff MCCU this season.
And even though Notts survived the final 12 overs to reach 47 without loss, Somerset will still hope to close out their second victory of the campaign on the final day.
Nottinghamshire captain Chris Read played a lone hand to save his side from total collapse in their County Championship fixture with Somerset at Trent Bridge.
Read, on 52 overnight, advanced to his 21st first-class century and finished 104 not out from a Nottinghamshire first-innings score of 162 all out.
The former England wicketkeeper hit 15 fours and two sixes in his 135-ball knock and dominated a last-wicket stand of 56 with Harry Gurney (6) after Somerset seamer Peter Trego (5-53) reduced the home side to 106-9 from a starting position of 93-6.
Somerset skipper Marcus Trescothick hobbled off after hurting his right ankle in the field during the morning and went for a scan, leaving Lewis Gregory to open in his place.
Trescothick missed the final three Championship games of last season after damaging the same joint.
Gregory (6) was bowled in the sixth over by Notts seamer Ben Phillips (1-21), playing against his former county, before second-wicket pair Arul Suppiah and Nick Compton forged a half-century stand.
Suppiah unfurled some elegant strokes to reach 50 from 95 deliveries, including eight fours, while the in-form Compton took a more sedate approach with 19 off 88 balls.
Somerset had reached 78-1 in the afternoon when rain arrived at Trent Bridge to wipe out the remainder of the day.
An unbeaten half-century from Nottinghamshire skipper Chris Read could not stop Somerset taking control of a rain-affected first day at Trent Bridge.
The visitors won the toss and took advantage of seamer friendly conditions to reduce the LV= County Championship Division One leaders to 93-6 in the 34.3 overs of play that was possible between frequent showers.
Nottinghamshire were 20-4 at lunch as Peter Trego skittled Neil Edwards (3), Michael Lumb (0) and Samit Patel (4) on his way to figures of 3-24.
James Taylor was also lost early in the afternoon session as he tried to whip Steve Kirby away through the leg side yet succeeded only in finding the hands of wicketkeeper Craig Kieswetter.
Read decided that attack was the best form of defence played some eye-catching strokes as he raced to 52 from just 60 balls by the end of play.
He will resume the second day with Paul Franks still to get off the mark at the other end, with Steven Mullaney being the sixth wicket down when he was bowled for 10 by Lewis Gregory.
