Ubaldo can be VERY wild at times; even last year when I used the Rockies in franchise, I'd have games with Jimenez where I couldn't find the strike zone. Eventually he'd settle down or work his way out of a jam. It is pretty realistic to how he pitches (I watch nearly every game), as he'll be sailing along and them bam: walk, walk, strikeout, walk, strikeout, groundout/flyout/strikeout (or this year it would be walk, walk, double, walk, strikeout, strikeout, groundout/flyout).
That is what I love about Classic pitching. With Analog (and meter) it's near-impossible to replicate that feeling of not having command of your pitches.
