Martin Guptill's batting has again been superb this season, but his fielding in any position is brilliant. Fielding at slip while Wes Durston was bowling at Chelmsford, he frequently did the work of 2 fielders as this sequence of photographs shows - starting at slip as the ball is bowled, but by anticipating the flight and the shot is able to field the ball in the fly slip position

Wayne Madsen pictured in the field at Chelmsford on Friday. In a calm, unflustered and determined manner, Madsen has led his side from the front this season including a superb win inside 3 days over one of the pre-season fancied sides, Essex. With two batsmen averaging over 50 (Guptill and Durston) and four bowlers averaging under 23 (Clare, Groenewald, Palladino and Wainwright) it's no suprise that Derbyshire have 4 wins and 3 draws from their opening 7 games. As Derbyshire sit well clear of the field at the top of the 2nd division tonight, Madsen, his team, and the whole of Derbyshire should be proud of their efforts so far
