Honestly I think Thom Brennaman just has me seriously confused as anything not a FB is a breaking ball to him I think.
Technically, all pitches 'break' downward. Gravity makes that happen unless you are throwing submariner. A secondary pitch is anything not a fastball.

Change ups aren't straight, though they generally don't move much more than one's fastball, they sink an extra 2-3 inches and have 2-3 inches of extra run, on average.

A breaking ball is a curve or slider (or slurve).
