I disagree that Whitlock is an average starter. He’s been treated with kid gloves because of his injury history and career IP numbers, but his only bad start was against Seattle, where he gave up 5 of the 14 ER he’s allowed in that role.
Houck on the other hand, is just being used in a way I will never understand. His role should be expanded into more games and higher leverage situations. If the Sale injury bumped Whitlock to the rotation, that’s fine. But the continuous use of Houck in this fashion while Diekman, Robles and Barnes flummox through high leverage situations seems inexcusable to me…
