Maybe, but I'm partial to an .890 OPS and a .341 BA with RISP, especially after 140 games of Harold, Oscar, Zimmer, and Naylor.
I'm not an expert on the Reds, but...
Wade Miley, 12-6, 3.09
Tyler Mahle, 11-5, 3.73
Sonny Gray, 8-7, 3.80
Vladimir Gutierrez, 9-6, 4.25
Luis Castillo, 7-15, 4.24 (age 28, ERA's of 3.40 and 3.21 the last two years)
Zach Plesac, 10-5, 4.45
I'm not exactly sure who Plesac would kick out of their rotation and how much adding Zach would improve their rotation.
I still need a little convincing to believe the Reds would part with Winker for Plesac and Rosario. Their shortstop is Kyle Farmer.
Farmer .256/.713 0.7 WAR
Rosario .279/.721 1.6 WAR
It seems like that deal would create a huge hole in their offense while making a modest improvement at SS and possibly at one of their rotation spots, although that's not for sure.
