The Reds are going with a six-man rotation out of the All-Star break through the trade deadline, meaning that Castillo's start Wednesday against the Marlins could be his final one with the team, Charlie Goldsmith of The Cincinnati Enquirer reports.

EDGE Analysis

Castillo is the most prominent starter likely on the pre-deadline trade market, and given the Reds' non-contending status and the fact it's unlikely they will contend in the near future, he is a good bet to get dealt sometime in the next week. The team will go back to a five-man rotation following the deadline.
