@ossobuco,
I checked, foxfyre, and your pitchers weren't slated to play today. That's just the time of the game in line with their names on the yahoo site.. as their team is playing today.
Yahoo will give you a carat (^) by their names if they are pitching. Sometimes yahoo is slow at this, and sometimes it gives you the starters for the week. I never trust it, as things can change, but it is semi reliable.
According to the yahoo carat indicators, Vasquez is pitching on Wednesday, and Jurrgens on (not shown yet)
I also check CBS.com, and after yammering about it, I see they're filling out the week's pitchers now. That too can change, but mostly doesn't.
To be extra safe, see what yahoo shows right before gametime on the day of a game.
This is a link to Monday's games -

Once the games are on, you can follow the play by play by clicking on game center... (if you see this now, you can follow the game tonight.. although it's about over.)
There are some other websites that do this too.
OK, checking the cbs scoreboard link,
Jurrgens is pitching on Tuesday.
Now I want to go look for the site with a gamelog that I liked last year. I had thought it was cbs, may be misremembering, or, they have changed.
