The Orioles cleared the way for Sisco to be the primary catcher in 2018, yet in some ways, he is less exciting than ever from a fantasy perspective. He has been one of Baltimore's top prospects ever since he was drafted in 2013, but what was once seen as a potentially plus hit tool, may only be average or above average. What was once seen as potentially fringe-average power, may not even be that, although in today's game anything is possible. He was uncharacteristically pull-happy (54.5 percent) in a brief 10-game stint in the majors, cranking out two home runs while striking out seven times in 22 plate appearances. It's possible he forgets everything he learned in the minors and shows up this year looking to pull everything out of the park, in which case his batting average will suffer. He is still not a great defender, so if he's not hitting, Caleb Joseph will play over him. A lot of outcomes are in play for his age-23 season, and most of them involve him not finishing as a top-15 fantasy catcher.

One of the top pure hitters in the minors for a couple years now, Sisco seems to finally be solid enough defensively that most evaluators think he can stick behind the plate. The power has never projected to be a plus tool, and at this point it is hard to even throw a future 50 grade on it. However, as a catcher with a plus hit tool, he packs enough offensive punch to make him an eventual top-10 fantasy option at the position. He posted a 135 wRC+ and 83:59 K:BB in 112 games as a 21-year-old at Double-A Bowie, and he even earned a four-game run with Triple-A Norfolk to close out the season. Sisco lacks Jonathan Lucroy's defensive chops, but in a few years he could offer that kind of offensive output. He should start the year at Triple-A and may take over as Baltimore's starting catcher sometime this summer.

Sisco was slowed by a pair of injuries last season, but when healthy he showed why his bat figures to play well for the Orioles. At just 20 years old, Sisco displayed advanced plate discipline and contact skills with an 11.0% walk rate and 13.7% strikeout rate at High-A before earning a promotion to Double-A. There may not be another catching prospect in the game that has a better hit tool than Sisco and it led the Orioles to hang on to him despite other teams inquiring at the trade deadline. His power is still a work in progress and that facet of his game may never evolve beyond a fringe tool. His eight steals were a bit of a surprise. Oblique and finger injuries kept Sisco out for over a month, but he got enough game action to prove he is ready to begin the 2016 season at Double-A. Matt Wieters accepted his qualifying offer and will return as the starter in 2016, but Sisco could be an option later in the year.

Sisco spent the entire 2014 season at Low-A Delmarva, playing 74 games at catcher and 40 games at DH. It is not uncommon for a minor league team to play catching prospects at DH once or twice a week, but in Sisco’s case, a lot of his value hinges on him sticking behind the dish. He only threw out 20 percent of would-be basestealers, so he will need to improve upon that as he moves up to High-A. Sisco’s second half at the plate really put him on the prospect radar, as he slashed .361/.424/.456 in 66 games. However, he slashed just .267/.362/.344 in 90 at-bats against southpaws on the season, and if he’s not adding value on defense, and doesn’t improve upon those splits, he will need to make the big leagues as the strong side of a DH platoon, which means he really has to hit.
