Jered Weaver didn’t really want to be here. All of his teammates were back in Southern California on Wednesday, but the Angels’ longtime ace was stuck in Arizona because he needed to make one more start. It would come against eager, aggressive, impatient Minor League hitters. And it would begin with a 24-pitch first inning that featured a prodigious three-run homer. But then something weird happened. Weaver actually started to have fun.
