If the Giants don’t achieve their ultimate dream — I’m assuming that dream has something to do with the World Series — it won’t be because they gagged under pressure. Sure, things got a bit tense Wednesday night in Kansas City, when the Giants bullpen blew up, Hunter Strickland went all Dirty Harry and Brandon Belt misread his GPS between bases. [...] the Giants spent half this season learning how to shrug off doom and disaster, and they seemed in full bounce-back mode at their informal workout Thursday on their home turf. The Giants are simply honoring the old baseball axiom: “Never get too high or too low, unless you’re Hunter Pence.” Crawford, being a Bay Area boy, is hip to that reference, but said no, he simply couldn’t pass up a golden opportunity to mess with Belt. When things start getting a little bit stale in the dugout and the locker room, he’s a guy that always seems to bring that energy, and helps bring a smile to your face. If you do try to follow in Pence’s lead, bring a thermos of truck-stop coffee. A year ago in New York, Mets fans, in that subtle New York way, started bringing Pence signs to the ballpark, signs that basically paint the man as a cornball dork.
