Well, the Herndon family was at Kauffman Stadium yesterday, as reported by Megan Stock of MLBlogs:
...Sweeney invited the whole Herndon family out to Kauffman Stadium as his special guests. Along with his parents and sisters, Emily and Katie, Matt took in some batting practice before the Royals game against the Twins on Tuesday, met a few Royals players and coaches and, this time, got face-to-face greetings and hugs from Sweeney and DeJesus. Just more than three months since his surgery, Matt is almost fully recovered, playing summer ball, getting ready for school to start (next week – yikes!) and gearing up for his fall league baseball to begin.
