There are two Orioles games today in two different places, against two different teams. This is one of the "fun" things of spring training: The split-squad day. Pretty much everybody will play between one or the other of these games.
The first of the two games, on the road against the Twins, will be on the TV on your computer, assuming you are an MLB.tv subscriber. That gets underway at the typical spring game time of 1:05. So you're totally in luck if you're just dying to lay your eyes on one of these guys:
1. Xavier Avery CF
2. Steve Tolleson 3B
3. Hyun Soo Kim LF
4. Christian Walker 1B
5. Henry Urrutia DH
6. Caleb Joseph C
7. Ryan Flaherty 2B
8. Dariel Alvarez RF
9. Paul Janish SS
SP - Tyler Wilson - RHP
Other pitchers who have made the trip, according to MASN's Roch Kubatko, are: Odrisamer Despaigne, Jason Garcia, Chris Lee, Parker Bridwell, Andy Oliver, Nick Additon, Donnie Hart, David Hess and Tanner Scott.
Not all of those guys will get into the game. After seeing their appearances on this offseason's Orioles prospect lists, I'd certainly be curious to see Lee, Hess, and Scott. The latter two are probably there as "just in case" guys and not really expected to get into the game.
The second game comes around at 7:05. Lineup currently unknown. It'll be at the O's spring home in Sarasota and feature a completely different set of Orioles, probably a more regular season-y looking O's lineup. That one will not be on television, I guess because MASN has such quality Saturday night programming in March that they can't possibly displace. It will be on the radio in Baltimore on 105.7 FM, so at least there's that.
