Clayton Kershaw is upset with his results this spring.After walking three Oakland A's batters and giving up a couple of RBI hits in the third inning of his second spring start, Kershaw told reporters in Arizona, "I'm searching for answers right now."This kind of accountability is refreshing, of course, since most pitchers after a bad Cactus League start will tell you they felt "great," and were unconcerned with the results. But is Kershaw's concern telling in any way?
