Three Giants are on the East Team - Gary Brown, Heath Hembree and Rickie Oropesa. Gary Brown is currently shown as being the starting CF for the East (who are the home team) and batting in the 2nd spot in the lineup. I doubt that Oropesa will get more than 1 AB later in the game, and we might not see him in the field at all. OTPH, Hembree should pitch an inning as he's working on his normal 1 day's rest.
The game is being live-streamed over the internet at this link:http://mlb.mlb.com/video/play.jsp?topic_id=7617858&content_id=25466845
