In the 1903 English cricket season Middlesex won their first County Championship title, winning eight and losing one of their 18 games in the season. Yorkshire, the defending champions and the only team to have won the Championship thus far in the 20th century, finished third after losing five games, including to Middlesex at Lord's and to Somerset for the third season running. They were, however, the only team to beat Middlesex; at Headingley in August, Yorkshire bowled Middlesex out for 79 in the first innings, and recorded a 230-run win.
The final County Championship table is shown below. One point was awarded for a win, none for a draw, and minus one for a loss. Positions were decided on percentage of points over completed games.
Points system:
Percy Clark and Bart King headed the wickets for the Philadelphians, who played 14 first-class matches in England, in addition to an abandoned fixture with Sussex. The American tourists won as many matches as they lost, with six of each, and drew two. Clark upstaged King, passing him on the wicket-taking tally with a pair of five wicket hauls in the final 110-run win over Surrey where King got six wickets. King averaged four runs less per wicket, however, and also contributed with 614 runs, the third-most in the team. In the batting, they were headed by captain John Lester, who made 786 runs in 13 matches.
