Walker has hit four-half centuries in eight county games this season
Essex batsman Matt Walker says they are eager to get over the disappointment of defeat on FP t20 finals day by making the CB 40 final at Lord's.
The 36-year-old was part of the side that lost to Hampshire at the Rose Bowl on Saturday but has not given up on one-day success this season.
He told BBC Essex: "There is a lovely carrot at the end of that with a Lord's final to get to.
"Having lost a one-day final the guys are really pumped to get there."
Essex sit third in Group B of the competition, five points adrift of top side Yorkshire, but with two games in hand.
The winner of each of the three groups goes through to the semi-finals with the best runner-up taking the fourth slot.
Paul Grayson's men also have the distraction of trying to avoid relegation from the top tier of the County Championship, with just three games remaining to haul themselves out of the drop zone.
We know now with 12 days of Championship cricket left we've got to play brilliant cricket all the time

"They're all massive games, I know that's a cliche but that's the way the structure is now in the cricket we play," added Walker.
"We've got three Championship games and we probably need to win all of them.
"And we've got five 40-over games left and we probably need to win all of them as well.
"We know now with 12 days of Championship cricket left we've got to play brilliant cricket all the time and we've got the players, it's just a case of producing it."
Essex can go some way to securing survival by getting off to a good start against Somerset on Wednesday.
