Didn't see this posted yet. Doesn't really tell you much but glad to hear Martin has been getting glowing reviews.

That's fair to be honest, he was pretty bad in all his starts. Rather him get a few strong innings out of the pen to build up some confidence and make sure his arm is good. Having another arm throwing gas out of the pen is a good thing.
They list Kirk as heavier than Vlad. Some of these guys man I don't get how they can have so many resources available to them and still not be able to get their conditioning under control.
Not sure if you heard the interview from Montoyo but he said Kirk is only on the taxi squad for developmental reasons. They don't see him getting on the active roster.
