their lack of domestic appearances. Trescothick was overshadowed by Michael Vaughan during the 2002–03 Ashes series, averaging only 26.10 with a top score of 72 in comparison to Vaughan's average of 63.30 and three centuries. Trescothick averaged 31.60 across 10 matches in the VB Series, but England were outplayed by Australia throughout the tour. Trescothick failed to excel in the 2003 World Cup as England failed to qualify for the knock-out stages. In his five matches, Trescothick's top score was 58 against Namibia, with a tournament average of 23.20. Continued success in 2003 and 2004 Trescothick played well against a weak Zimbabwe side in the two-Test series in May–June 2003, and scored an unbeaten century in the three ODIs against Pakistan averaging over 100. His form continued in the 2003 NatWest Series, with 114 not out against South Africa. The opening stand with Vikram Solanki of 200 runs was the highest first-wicket partnership for England and provided the first instance of both England openers scoring centuries in the same innings. Trescothick maintained his form in the South Africa Test matches; a career-best 219 at The Oval completed a successful series in which he averaged 60.87. In Bangladesh, scores in the nineties against both the President's XI and Bangladesh A were followed by a century in the first Test, and 60 in the second. He scored one half century in the three ODIs, although England only used five batsman in the comfortable victories. England played poorly against Sri Lanka, with Trescothick finding it hard to build a large innings. He attempted to take control of the match with 70 at Colombo, as England tried to get something from the series, but was also criticised for his poor catching. His form in the tour to the West Indies in March and April 2004 was mixed. After several low scores in the Test series—Trescothick started with only 20 runs from his first five innings—he reached two half-centuries, but failed to make a substantial match-winning contribution. This poor touring form may have been the start of the troubles that would rule him out of international cricket in the future. Trescothick said, "The hardest thing for me has been the pitches. So far nets and the matches have been on average surfaces and runs have been hard work...In England you get used to good practice surfaces so the rhythm of batting comes pretty easy [sic]."
