Lurking behind the opener to come in and dominate in the early to middle innings seems to be working for Pivetta in away you almost never see. From a disaster of a season in the traditional rotation role, Pivetta has risen into a unique self-made role, and he isn't really eating less innings as a result, he's just starting later in the game with less pressure on him to come storming out the gate.
I think the key here is the reduced pressure. Pivetta is often coming in with an early lead in a way that starters don't normally have the luxury of. As long as the bats keep creating early runs for him Pivetta can relax on the mound and focus on just being the pitcher he can be. And Pivetta's stuff has always been excellent, so a situation that places him in a good headspace has been key to unlocking the potential he's always had.
It's such a unique and effective solution that I wonder if other teams aren't studying it. It's not really a new notion, but seeing it succeed this dramatically to turn a pitcher's career around makes me think other teams may start experimenting with it if they have a guy with starter stuff who's just not in a good headspace.
