Gonzalez enjoyed a five-game cup of coffee with the White Sox in 2013 but has been stuck at the Triple-A level ever since. He hit just .243/.298/.327 with Triple-A Toledo in 2016 and will likely play out his entire age-26 season as minor league depth, barring several injuries behind the plate in Detroit.
Zarraga spent the last two years in the Dodgers organization, most recently posting a measly .434 OPS with Triple-A Oklahoma City. Due to this and the general logjam at catcher in the Reds organization, the 27-year-old will likely just be an organizational depth piece from here on out.
The 27-year-old catcher has made a few appearances in the big leagues, although he hasn't been able to translate his bat to the majors for the most part. Pair this with the plethora of other catchers in the Reds system, and it seems like Brantly will spend another year as organizational depth.
The 30-year-old backstop has bounced around the minor leagues in his career, although he's never been able to stick at the major league level. Monell will look to boost his stock with some time in the hitter-friendly KBO for the next season, likely with the hopes of creating some intrigue for next year's offseason.
The 25-year-old backstop slashed .227/.252/.361 with three homers and 15 RBI over 126 plate appearances at the big league level in 2016. Those numbers represented a notable improvement over his 2015 cup of coffee, which consisted of a scant 35 plate appearances and saw Maile generate a .171/.171/.257 line. With Ramos not expected back until late May at the earliest, Maile figures to see a decent amount of playing time while platooning with Casali to open the season, with his exact role after Ramos' return likely to be largely predicated on how he acquits himself during that period.
Despite slashing .186/.273/.336 over 256 plate appearances last season at the big league level, Casali displayed a knack for making it count when he did make contact, rapping out 18 extra-base hits (10 homers) and tallying 25 RBI. His bloated 32 percent strikeout rate certainly needs improvement, but Casali's solid work behind the plate and occasional pop is likely to keep him involved even after Ramos is healthy enough to play, which is likely to be in late May or early June. In the interim, he figures to platoon with Luke Maile to begin the 2017 campaign.
Iannetta's agent also represents Jose Bautista, and the conversation reportedly took place as part of a larger meeting that covered both free agents. Given the departures of Dioner Navarro and Josh Thole from the 2016 roster, Toronto's backup catching job remains up in the air. While Iannetta has graded out negatively in Defensive Runs Saved (DRS) over the past several seasons and is not known as a strong pitch framer, the 33-year-old did manage to throw out 20 of 65 attempted base stealers in 2016 for a 31% success rate (league average rests around 25%). His offensive upside also offers potential, and his production at the plate would likely get a boost playing in Toronto's hitter-friendly Rogers Centre.
Turner will essentially provide the Reds with a warm body capable of setting up behind the dish in case Devin Mesoraco were to suffer an injury during spring training. He has not played above Double-A and offers limited upside. Look for him to be subjected to waivers and offered back to the Twins at the end of spring training.
The Reds will receive cash and a player to be named later in the deal. Torrens, a 20-year-old catching prospect, missed all of the 2015 season following surgery to repair a torn labrum and played in just 52 games in 2016. He has some on-base skills, posting a 13.4 percent walk rate at Low-A last season, but he won't be fantasy relevant anytime soon. The Padres will have to keep Torrens on the active roster all season, otherwise he will be exposed to waivers and offered back to the Yankees. He will probably simply be stashed on the bench if he breaks camp with the club, as he is unlikely to be ready to handle the offensive or defensive side of the game at the big league level.
Torrens will officially be a Cincinnati Red for now, though it seems he could land in the Padres uniform in the near future. The 20-year-old back stop spent the 2016 season with the Yankees organization, posting a .687 OPS across multiple Class A levels. Regardless of his landing spot, Torrens would ultimately be returned to New York if he gets removed from the major league roster from whichever team he ends up with and clears waivers.
