400 Runs in a Test Match

The correct answer to this question is Graham Gooch.

In a Test match against India at Lord's, in 1990, Gooch scored 333 runs in the first innings and 123 in the second. Total 456.

Brian Lara was the first man to score 400 runs in a Test Match innings. He was actually the third man to score 400 runs in a Test; the second was Michael Taylor, for Australia against Pakistan in 1994 (334 not out and 92; total 426).
