Plum Warner's MCC team — the first official tour to Australia — arrived as underdogs after four straight Ashes losses. Warner had to reshape the team after Archie MacLaren publicly objected to his appointment, and the press ridiculed several selections. Among them was R.E. Foster, the Worcestershire amateur, batting at six on debut.
In the first Test at Sydney, beginning 11 December 1903, England won the toss and were 73 for 3 when Foster joined Len Braund. Foster would bat through that day, all of the next, and into the third for 287, an innings of nearly seven hours containing 37 fours. He shared a 130-run partnership with Braund, then 192 for the last wicket with Wilfred Rhodes (40 not out) — a tenth-wicket Test record that endured for over a century.
Foster's 287 was the highest score in Test cricket until Andy Sandham's 325 in 1930. It remains, more than 120 years on, the highest score by a Test debutant. Foster also held the record for the highest Test score at the SCG until Michael Clarke's 329 not out in 2012. England won the match by five wickets and went on to take the series 3-2, regaining the Ashes.
