Welington Castillo

Welington Castillo (elbow) not in Diamondbacks lineup Tuesday

Welington Castillo is not in the lineup tonight after getting hit in the elbow with a pitch yesterday. Oscar Hernandez will start at catcher and bat eighth against the Mariners.

What It Means:

Castillo is hovering just above average this year with a .312 wOBA and 0.07 nERD, but he has been hot in July with a .363 wOBA. In 18 plate appearances this year, Hernandez has a .246 wOBA and -0.11 nERD. Our algorithm ranks him last in terms of daily fantasy points among all catchers tonight.
