During another year of catcher volatility, Realmuto was a rock, chipping in across the board while setting career highs in games played, home runs, RBI, runs scored and OPS. Realmuto's 28 stolen bases over the past three seasons lead backstops, significantly boosting him in a landscape with diminishing speed. Though his HR/FB has climbed in each of the last two seasons, he'll likely struggle to top last year's power production given his career 47.8 percent groundball rate. The backstop remains a safe bet to at least stay afloat in batting average, however. Despite less than desirable walk rates, he rarely strikes out (81 percent career contact rate) and has improved his BB/K in each full season. The team was stripped down this offseason, but Realmuto may also be on the move, so it's too early to say what the context ramifications will be. He turns 27 in March and does enough overall to comfortably profile as a top-five option at the position.

The stats haven't been flashy, but Realmuto's inspiring performance from 2016 was right in line with his offensive numbers in the minors. He gets extra fantasy pub for the dozen steals he accumulated last season, an asset that gets highlighted given the dearth of steals available at the catcher position. Still, the crux of Realmuto's future value is with the stick, not his legs. Counting on that speed from a player that has to get in a crouch 150 times a game sets buyers up for disappointment, particularly for one whose propensity for triples in 2015 dried up completely last season. Still, his pull-heavy tendencies could morph some doubles into home runs as he matures. As promising as last season was, however, Realmuto's lack of walks could very well come back to bite him as his unsustainable BABIP (.357 in 2016) comes back to earth, with the downside for a sub-.300 on-base percentage if the walks don't materialize. Be careful.

After an 11-game stint last year, Realmuto earned his first significant major league playing time with the Marlins and hit .259/.290/.406 in 126 plate appearances. Realmuto has posted a professional OBP above .350 just once and shouldn’t be expected to be an on-base machine — he walked just 4.1 percent of the time. But he makes contact at about a league average rate (15 percent strikeout rate) and showed plus power even with the cavernous walls of Marlins Park keeping him down. Realmuto managed 10 home runs and a shocking seven triples. The last catcher to muster seven triples was Darrell Porter in 1979, and it has happened just five times since 1970. Realmuto also stole eight bases and has attained double-digit stolen base totals in the minors, making him the rare speedster to play the catcher position. With full-time duty next year, he could put up a 10-10 season.

Since being drafted in the third round of the 2010 draft, Realmuto has progressed steadily through the Marlins' system. He struggled in his first taste of Double-A in 2013, batting .239/.310/.353 over 106 games before improving to a .299/.369/.461 line last season over 97 minor league contests. The strong season earned Realmuto a brief stretch in the majors in mid-June and a handful of September games as well, highlighted by a 3-for-5 effort with a double and a triple during the final week of the season. The 23-year-old backstop stands 6-foot-1 and offers a steady line-drive stroke with a strong contact rate (13.9 K% in the 2014 at Double-A) and patient approach at the dish. Realmuto also offers plus defense behind the plate, gunning down 22-of-58 would-be base stealers last season between the majors and the minors. Jarrod Saltalamacchia remains the Marlins’ primary option behind the dish, so Realmuto is most likely headed to Triple-A to further develop his craft and play every day. He could, however, push veteran Jeff Mathis for at-bats down the line and remains locked in among the team’s top prospects as the heir apparent behind the dish.

While Kyle Skipworth's prospect status is fading fast, Realmuto, a converted shortstop, did enough last season to inherit the Marlins' Catcher of the Future tag. He's still raw behind the plate, but the arm that could have made him a highly recruited quarterback is already gunning down basestealers at a nice clip, and his bat showed signs of progress as well at Low-A (12 homers and 13 steals from a kid spending most of his free time doing catching drills isn't bad at all). While Buster Posey comps are inevitable and misguided given the position switch, he is smart and athletic enough to develop into a solid major league backstop down the road if Miami is patient with him, or maybe switch the misguided comps from Posey to Craig Biggio if his new position doesn't take. He's still a few years from the majors, but Realmuto's athleticism and skill set make him an intriguing prospect at fantasy's thinnest spot.
