Dave Chisnall was a losing finalist for the second week in a row at the 19th Players Championship event of the year in Coventry on Saturday.
Chisnall, who was defeated in the Grand Slam of Darts final by Phil Taylor six days earlier, lost out 6-2 to Ian White at the Ricoh Arena.
The Morecambe darts ace comfortably saw off Adam Hunt (6-3), Mick Todd (6-2) and Dean Winstanley (6-0) in his opening rounds to breeze into the last 16.
A narrow 6-4 win over Michael Smith came next for Chizzy before he turned on the style to dump Adrian Lewis out of the tournament, winning 6-2 with a 102.92 average.
After battling his way to the final in Wolverhampton the week before, Chisnall showed more of his fighting spirit as he came back from 5-3 down to beat Brendan Dolan 6-5 in the semi-finals and set up the final showdown with White.
Chizzy would again start slowly in the final as White raced into a 3-0 lead, but despite pulling the game back to 4-2, White was not in any mood to let his grasp on a first PDC title in just over a year slip.
Diamond just held on to his throw in the seventh leg, taking out 18 to move 5-2 in front, before saving his best checkout of the afternoon for the final leg of the day as he took out 146 to seal an impressive win in spectacular fashion.
The following day in the 20th Players Championship event, also at the Ricoh Arena, Chisnall exited at the second round stage.
After a 6-1 victory over Joe Lacey in round one the Morecambe ace was knocked out 6-3 by Daryl Gurney.
Chisnall’s performance in the final two Players’ Championship events has set up a first round tie with Adrian Lewis at the Cash Converters Players Championship Finals on Friday.
The Morecambe ace goes into the event as the 19th seed at the Butlins Minehead Resort and will take on the number 14 seed in Lewis who won March’s UK Open on the Minehead stage.
Michael van Gerwen will begin his defence of the title against Raymond van Barneveld, while top seed Gary Anderson takes on another Dutchman, Christian Kist.
The first round will be played across two sessions on Friday, November 28.
The second round will take place the following day with the quarter-finals taking place in Sunday’s afternoon session and the semi-finals and final held in the evening session.
