LONDON -- Chicago Cubs right-hander Marcus Stroman left Sunday's game against the St. Louis Cardinals in the fourth inning with a blister on his right index finger.
Stroman entered the game with an NL-best 2.28 ERA and was 7-0 in his last seven starts going into the series finale in London.
Stroman was pulled with one out in the fourth after Paul Goldschmidt put the Cardinals ahead 5-4 on a sharp single that scored Tommy Edman.
He allowed nine hits and six runs, all earned, to go with two strikeouts and a walk.
