I don't think it's as much a line against Griffin as it is a line for Pineda. Sabermetric gambler systems LOVE Pineda. He misses a lot of bats and when successful, doesn't walk guys. A lot of pitches usually, but theory is he gets his 6 and turns it over to the big three.
That being said, I hopped on Rangers +132 last night before the 9th inning collapse anticipating to ride the Rangers hot streak. If it gets too low may buy off as I'm also on the U9. I think that may be the best play.
