The Pirates have announced that they've claimed righty reliever Guido Knudson off waivers from the Tigers.
You might think they made that up, but they didn't -- "Guido" is Knudson's given name. The 26-year-old pitched briefly in the big leagues last season and struggled, but got better results with Triple-A Toledo, posting a 2.55 ERA and 9.4 K/9, albeit with 4.5 BB/9. In the big leagues, his average fastball was a bit above 93 MPH, and he also threw a slider around 83. He demonstrated pretty extreme fly-ball tendencies with Toledo, for whatever that's worth. Essentially, he looks like a somewhat generic righty relief prospect, although the strikeout numbers are somewhat promising, and perhaps the Pirates see something they can work with from a scouting perspective.
The Tigers only added Knudson to their 40-man roster late last season, so he has options; the Pirates can therefore afford to keep him around as a bit more of a long-term project, or move him back and forth between the minors and the big leagues as they so choose. Knudson has also demonstrated the ability to work multi-inning stretches, a valuable trait in a reliever who's optionable.
Knudson, incidentally, was a 28th-round pick out of the University of California, San Diego in 2011. I was teaching gigantic lectures to non-music majors there from 2007 through 2010, so it's entirely possible he was in one of my classes.
