Astros Spring Training

I live in the Tampa area and I’m wanting to check out the Astros Spring Training and would like to try to score some autographs, but really just pictures with the guys. Does anyone have any tips they can share? Should I just show up at the facility? Get tickets to one of the games? I know the WBC is happening and I would like to see Tuve with the team so I’ll be going mid March more than likely. Thanks in advance!
