James Anderson's previous best match analysis was 10-81
James Anderson recorded the best match bowling analysis of his career, 11-109, to help Lancashire wrap up an eight-wicket win against Sussex at Hove.
The England fast bowler claimed three more scalps on the last morning to take 5-53 as Sussex were bowled out for 167.
Needing 158 to win, Lancashire openers Tom Smith and Paul Horton fell cheaply for the second time in the game.
But South Africans Ashwell Prince (91 no) and Francois du Plessis (58 no) saw Peter Moores' side home.
Anderson had already produced his first five-wicket haul for his county in five years in the first innings, taking 6-56.
He had only been given special permission to play as a warm-up for the forthcoming Test series with West Indies.
And, on the day when his county team-mate Andrew Flintoff came home from the IPL to face knee surgery, the England and Wales Cricket Board can at least feel pleased with one Lancastrian bowler's week's work.
Lancashire coach Peter Moores told BBC Radio Lancashire:
"We played really good cricket. We played good cricket all the way through and that resulted in us getting in a position at the end for what seemed like quite a comfortable victory.
"The side has character and are prepared to work really hard. They had to work very hard for the whole game. This was not an easy win.
"Anderson bowled beautifully and to watch him commit totally to a Lancashire fixture when he knows all the cricket he has coming up was testament to him. He put his heart and soul into the game. He's an example to everybody else at the club."
Sussex coach Mark Robinson told BBC Sussex:
"We had great windows to win the match but at one point it was a case of which team wants to throw it away most, and in the end it was us.
"We should have probably bowled them out for 150 in the first innings. If we'd caught our catches, we would have bowled them out for 200 and had a good lead.
"Every time we had a little partnership going and getting ourselves in a position, we presented the opposition with a wicket, which was disappointing. We've not been able to take the key moments and it's cost us."
