What It Means:

Diaz caught on Tuesday, and would have given way to Francisco Cervelli (flu) who was scratched on Wednesday afternoon. Chris Stewart instead mans the backstop against the Milwaukee Brewers today.

The Pirates' 4.54 implied total is fairly middling on today's slate, but it comes in Miller Park (1.022 park factor) and against Junior Guerra who has the sixth-lowest strikeout rate, third-highest walk rate, and seventh-most fly-heavy ground-to-fly ratio on the slate. The Pirates have sneaky hitting upside here.
