How good is Rasmussen?

I admittedly know jack about the guy OSU is pitching tomorrow. I know he was the 31st pick, that he's coming off an injury, and he has a microscopic ERA of 0.79. That tells me the stuff is good and he is another elite arm that we will be facing.

So I did some digging and the first thing that stood out to me is the amount of time he's seen on the mound the last two seasons, only 59 innings pitched. To put that into perspective we have pitched Austin Bain 53 innings in that same timespan. Before this season, he had an ERA of 3.11 his two years at Oregon State. That's certainly not bad, but it's not 0.79 either. I also found that Rasmussen has only made two appearances for Oregon State all post season, so again, he hasn't seen much time on the mound and he's not going 7 or 8 innings.
