premise: A left-handed pitcher wearing the number 40 is throwing a ball to a catcher.
hypothesis: he throws a strike
explanation_1: Just because the pitcher is throwing a ball that does not mean he threw a strike.
explanation_2: There is no mention of a batter in sentence one. For the pitcher to throw a strike, a batter has to swing and miss an oncoming ball. Sentence one states that the ball is being thrown to the catcher, which would indicate that there is no batter on the mound.
explanation_3: Just because a left-handed pitcher wearing the number 40 is throwing a ball to a catcher doesn't mean he throws a strike.
