Middlesex County Cricket Club in 2005 played their cricket in Division One of the County Championship and Division Two of the totesport League. They started the season at 9–1 to win the County Championship title. In their first fixture of 2005 they beat Nottinghamshire comfortably in a rain-affected Sunday League game, and followed it up with a rain-affected draw in the County Championship against the same team. The second Sunday League game saw a thumping win against Lancashire at Lord's. They were then defeated in the Championship by Warwickshire County Cricket Club, before defeating Worcestershire in the Sunday League on 1 May to maintain their 100% record in the Sunday League. Then on 4 May they beat Northumberland to progress to the Second Round of the C&G Trophy. A defeat by Hampshire and a win against Gloucestershire then followed in the County Championship, before their unbeaten run in the National League was ended by hungry Hampshire Hawks. On 17 May they were eliminated from the C&G Trophy at the Second Round stage by Northamptonshire, and yet another one-day game without a win came at Gloucestershire, where rain ended the game prematurely. They then played a Championship game against Sussex, who just held on for a draw, leaving Middlesex seventh in Division One at the end of May. Middlesex then lost a friendly match against the students of Cambridge UCCE, and also lost their table lead in the National League with a loss to Essex. The next Championship game was a high-scoring draw with Surrey, before keeping up their one-day title challenge with a win over Northamptonshire, taking revenge for their loss in the C&G Trophy. In a high-scoring match at Southgate, they beat Glamorgan despite losing more wickets, and on the same pitch the following day they amassed 314 to beat Nottinghamshire in the National League. Middlesex also got good results in the Twenty20 Cup group stage, as they avoided the rain, but they lost twice to Surrey. They did have the fortune of meeting a dejected Kent side twice, beating them both times, and also beat Hampshire and Essex – enough to see them through to the quarter-finals on more wins. That was followed up by a seven-wicket win in the Championship over Hampshire, before their luck ran out, and they lost a high-scoring match to Gloucestershire in the National League before saying goodbye to the Twenty20 Cup with
