The Cincinnati Reds announced a surprising move this afternoon in that Jon Moscot will be promoted from Triple-A Louisville and start tonight over Raisel Iglesias.
RHP Jon Moscot (#46) will start for the Reds tonight instead of RHP Raisel Iglesias. Moscot will be making his Major League debut.

What you see in the tweet is the only news reported so far. It’s currently unknown why Iglesias won’t be starting or what the corresponding roster move is.
