MLB Pipeline will unveil its 2019 Top 100 Prospects list with a one-hour show on MLB Network and MLB.com on Saturday, Jan. 26, at 8 p.m. ET. Leading up to the release, we look at baseball's top 10 prospects at each position.

There's a good amount of turnover on this year's Top 10 Catching Prospects list compared to the 2018 version. That starts at the top, with a member of the 2018 Draft Class, Joey Bart, leading the way.

Francisco Mejia , now with the Padres, continues to be a mainstay, sitting in the top two for the third straight season. Keibert Ruiz of the Dodgers, the A's Sean Murphy and Danny Jansen from the Blue Jays are the other holdovers from last year's Top 10. Graduation caused some serious turnover, with Carson Kelly , now with the D-backs, Jorge Alfaro (Phillies), Chance Sisco (Orioles) and Victor Caratini (Cubs) all moving on to larger big league contributions.

Top tools

Hit: Mejia (60)

Mejia has hit at pretty much every stop in the Minors, starting with his 50-game hitting streak and .342 average in 2016. Following his trade to the Padres last year in the Brad Hand deal, he showed what the fuss was about by hitting .328 with Triple-A El Paso en route to making his San Diego debut. His ability to swing the bat from both sides of the plate is well ahead of his defense behind it.

Power: Bart (60)

The No. 2 overall pick in last June's Draft, Bart not only has a strong college power resume, with double-digit home runs as a sophomore and a junior, but he showed that it would translate immediately in the pro game when he hit 13 home runs in just 45 Northwest League games during his pro debut. He has the potential to hit at least 25 homers annually.

Run: Varsho (55)

There are some who feel Varsho is athletic enough to play second base if catching doesn't work out, and he certainly did nothing to dampen that evaluation during his first full year. Varsho stole 19 bases in 22 tries in just 80 California League games. He then went on to swipe eight more during his Arizona Fall League stint.

Arm: Mejia, Murphy (70)

Mejia has thrown out 33 percent of potential basestealers in his Minor League career. Last year, that was down to 28.9 percent, though he also spent less time behind the plate compared to other seasons. Murphy threw out 34.3 percent in 2018, which actually brought his career percentage down to 35.5 percent.

Field: Murphy (65)

Murphy would be the runner-up on the All-Defense Prospect Team thanks to his all-around work behind the plate. In addition to his arm detailed above, he's agile with excellent blocking, receiving and game-calling skills. He gets very high marks for his ability to work with a pitching staff.

Superlatives

Ceiling: Melendez

The 2017 second-round pick showed off all of his skills during his first full season. He finished fifth in the South Atlantic League in home runs and slugging percentage, and he should tap into his raw power even more as he refines his approach. Behind the plate, Melendez used his plus arm to throw out nearly 42 percent of those trying to steal last season.

Floor: Ruiz

Murphy could be a candidate if you wanted to focus solely on defense -- his glove will make him a big leaguer. But Ruiz's bat, with the ability to hit for average and power, provides a little more certainty that he'll be a big league regular at the position.

Rookie of the Year candidate: Jansen

There are several on this list ready to contribute in 2019, but Jansen appears to be the only one heading into the season as the No. 1 backstop on the depth chart. He had a solid big league debut in August and September last year to build a foundation for his first full year in the big leagues.

Highest riser: Hernandez

Hernandez began 2018 as the Rays' No. 20 prospect, but was up to No. 7 by the end of the season. Now he's jumping onto this Top 10 list for the first time after a year that saw him hit 21 home runs in his full-season debut while throwing out 36 percent of runners trying to steal.

Humblest beginnings: Knizner

The Cardinals have a knack for finding late-round talent and it looks like they've done it again with Knizner, a seventh-round pick in 2016. The North Carolina State product was a third baseman until he began his catching career as a sophomore and now he's ready to be a big leaguer, thanks to a .310/.373/.460 line and a 36.2 percent caught stealing rate.

Most to prove: Mejia

Yes, Mejia has hit pretty much everywhere he's been in the Minors, but he has a .583 OPS in 76 big league plate appearances, a small sample size for sure. That, combined with questions about his ability to catch full-time and showing he was worth trading for, makes the spotlight a little brighter on him in 2019.

Keep an eye on: William Contreras, Braves

The younger brother of Cubs catcher Willson Contreras , William had a very strong first taste of full-season ball, earning a promotion to the Class A Advanced Florida State League at age 20. He has a solid approach at the plate with some pop (11 homers in 2018) in addition to a strong arm and solid receiving skills behind it.
