Who will be the odd-man out when the Reds finalize their 40-man roster?

The clock is ticking and the Cincinnati Reds have yet to finalize their Opening Day roster. While many positions are spoken for, there's still a little business left to take care of.

The Reds reassigned Henry Ramos to minor league spring camp and optioned Bennett Sousa on Monday which essentially solidifed the team's bullpen.

But, with two pitchers (Tejay Antone and Justin Dunn) headed to the 60-day IL and three non-roster invitees (Jason Vosler, Alex Young, and Derek Law) yet to be added, there's at least one more player in line to lose his spot on the 40-man roster.

Which Reds player will lose his 40-man roster spot before Opening Day?

We all know the Cincinnati Reds starting rotation is set. With Bennett Sousa having been optioned on Monday, the Reds bullpen will likely consist of Alexis Diaz, Fernando Cruz, Alex Young, Derek Law, Ian Gibaut, Reiver Sanmartin, Buck Farmer, and Joel Kuhnel.

But with Joey Votto and Nick Senzel beginning the year on the Injured List and Cincinnati having released Chad Pinder a few days ago, there are still questions when it comes to the position players.

If the Reds intend to name infielder Jason Vosler part of the Opening Day roster, he'll first need to have his contract selected and be added to Cincinnati's 40-man roster. Placing Justin Dunn and Tejay Antone on the 60-day IL opens up just two of three necessary. So what happens?

First, C. Trent Rosecrans of The Athletic (subscription required) is suggesting that Stuart Fairchild would receive one of the last two remaining spots on the Opening Day roster despite the fact the outfielder has already been optioned. That's certainly a possibility.

There could be some off-the-wall, out-of-left-field injury to a player that may require placement on the 60-day IL, but that has yet to come to light. The most likely scenario would be designating someone from the 40-man roster for assignment. So who gets dumped?

Ricky Karcher, Casey Legumina, Brandon Williamson, Levi Stoudt, and Lyon Richardson aren't going anywhere. The list of players slated to begin on the 10-day/ 15-day IL includes Joey Votto, Nick Senzel, Lucas Sims, Tony Santillan, and Luke Weaver.

There's no way in the world the Reds plan to DFA their top two prospects (Elly De La Cruz and Noelvi Marte) on the 40-man roster, so we're left with Nick Solak, Michael Siani, and the aforementioned duo of Stuart Fairchild and Bennett Sousa.

After hitting just .100 during spring training, the smart money is on Solak being DFA'd. The fact that Nick Senzel is getting reps on the infield and Jose Barrero is seeing time in the outfield, only increases the likelihood that it's Solak who's shown the door before Thursday's deadline.

Nick Solak, if he passes through waivers, could always accept an assignment to Triple-A and remain in the Cincinnati Reds organization to begin the season. Keep in mind that all this hinges on the idea that no one from outside the organization is brought in between now and Thursday.
