|LV= County Championship Division One, Trent Bridge|
|Close, day two: Sussex 391 v Nottinghamshire 310-3|
|Notts 6pts; Sussex 5pts|
Centuries from James Taylor and Championship debutant Jake Libby helped Nottinghamshire make a solid first-innings reply against Sussex.
Libby (108) and Taylor (101no) put on 181 for the third wicket as Notts reached 310-3 at the close of day two.
Opener Alex Hales also contributed with 57 at the top of the order.
Earlier, last-wicket pair Ashar Zaidi and Lewis Hatchett added a further 33 runs for the final wicket as Sussex posted 391 all out at Trent Bridge.
Notts still have hopes of finishing second in Division One, but a wonderful 178 from Sussex opener Chris Nash on day one put them on the back foot.
Resuming on 358-9, Sussex held up Notts for nearly eight overs of the morning session before Harry Gurney was able to take the final wicket, bowling Zaidi for 37.
Hales and 21-year-old Libby added 97 for the first wicket, but when both Hales and Michael Lumb departed in quick succession, Taylor was a more than able partner for the Plymouth-born youngster.
Libby fell to Hatchett shortly after reaching his century from a sedate 247 balls, while Taylor got to three figures for the first time in the Championship this season with a single off Steve Magoffin in the penultimate over of the day's play.
Notts batsman Jake Libby:
"The whole day has been crazy, it's just been surreal. I was very nervous in the 90s and obviously to get it away past point for the hundred was a great moment.
"Both parents were in the crowd and it's obviously a great moment for them. I'm just chuffed with how it has gone."
Sussex opener Chris Nash:
"I always enjoy coming here, but it's been a very tough day.
"You really have to work hard for your wickets out there - it's a very good pitch to bat on."
VIEW FROM THE COMMENTARY BOX
BBC Radio Nottingham's Dave Bracegirdle:
"Many congratulations to Nottinghamshire's two centurions, with Jake Libby deserving of special praise.
"The youngster became only the 11th man to score a ton on his county debut and it was somehow fitting that the last to do it, James Taylor, was at the other end and able to share the moment."
