From the article:
we covered military opening day with the San Diego Padres and no other professional team goes as far as they do to support our men and women in uniform. While covering the Padres on this occasion and a few others, we became friends with their PR staff’s which include George Stieren and Warren Miller. They just had their colleague Erik Meyer send me the story and video of 11-year-old Brad Warnick, joined on the mound by mother Irene and 8-year-old sister Ashley, who thought they were just representing the USS Midway Museum in San Diego in honor of their fathers service in the Navy. BUT…..dressed in full Padres catching gear behind the plate was Petty Officer 1st Class Rick Warnick, their father & husband. Petty Officer Warnick is part of the crew currently deployed on the USS Nimitz, scheduled to return next month. Warnick was flown home early to surprise his family on the field through cooperative efforts of the USS Midway Museum and the Navy. This video is what it’s all about.
