Hi Barry,
Yes, that's an electronic scoreboard and unfortunately it was never used for game statistics. Throughout the entire game it rotated MLB's advertisers.
I don't mean to clog up the thread with pics but even back in March I had hope for these guys. Here's a few I snapped in Scottsdale and one more where they ended up.
Rowand leading off against the Brewers with Zito totally unaware of his 2010 fate! Another of Will Clark tossing a baseball to a kid.
