premise: David Thomas Bush (born November 9, 1979) is an American former professional baseball pitcher. He played in Major League Baseball (MLB) for the Toronto Blue Jays, Milwaukee Brewers, Texas Rangers, and Philadelphia Phillies. Bush also played for the SK Wyverns of the KBO League.
hypothesis: David Thomas Bush played in the MLB before the KBO League.
reason: It says he played for both, but not which one was first. KBO comes second in the text so that might be what confuses the model.
