MMP doesn't look to full, but you could definitely hear the boo's. It was great, and it lasted about 10 - 15 secs.
Damn... I wish Astacio threw that splitter more when he has 2 strikes on a batter. It looks impossible to lay-off of when you're up against a possible K. He's got the tools... he's just got to put it all together (and this isn't like Redding... Redding's "stuff" was nonexistent once he got to the majors, and he never threw a single pitch that made me go "woah").
