It's hard to get a good read on pitchers when there is no live fielding, not to mention it's hard to get an idea of anything while four games are going at once. =)
After some major-leaguers put in some work, Chris Mason pitched four innings on the Triple-A field today and looked good. He also hit two batters and said he's working on pitching inside more. Chuck Tiffany, who hasn't pitched in a game since 2006, also went out there, so he could be getting close to a return. I saw Brian Henderson and Jino Gonzalez throw, too.
James Houser went at Double-A hitters for a while and seemed to be using his curveball more. Chris Fessler also saw some time and there's no telling how many pitchers I missed.
Sporadically looked at the high-Class A guys, at least enough to remember seeing Jeremy Hellickson and Josh Butler. Hellickson has such a slow and easy motion.
