Blue Jays Rumors

Catching depth throughout baseball is thin. When I rolled out my Top 100 Prospects list at FanGraphs in March, I had only four catchers included in that ranking: Travis d'Arnaud of the Mets, Mike Zunino of the Mariners, Austin Hedges of the Padres, and Gary Sanchez of the Yankees. Baseball America's list featured the same four backstops. Baseball Prospectus also had that same quartet, followed by two more names in Jorge Alfaro of the Rangers and Christian Bethancourt of the Braves.

As witnessed by the lists, it's an accomplishment for any organization to have one good catching prospect in a minor league system, let alone two. The New York Yankees organization is enviable in that regard. Sanchez, 20, has been a mainstay on the top prospects lists since he signed out of Venezuela in 2009 as a 16-year-old amateur free agent. He showed up as high as 42nd overall on the three lists mentioned above, and no lower than 57th. The offensive-minded catcher has impressive offensive skills, including plus raw power. His ascent through the Yankees system can be best described as slow and steady.

Signed the same year as Sanchez, J.R. Murphy was selected out of the high school ranks in the second round of the amateur draft and he's just beginning to receive the attention he deserves. A front office contact who is familiar with the catching prospect told MLBTR that Murphy "was signed as a player [people] thought would hit and might be able to catch."

The 22-year-old prospect has flashed offensive potential in the past with good control of the strike zone, gap power and the ability to hit for a respectable average — but inconsistency has been his downfall at the plate. So far this year, the Florida native is hitting .308 with 12 extra base hits, as well as 16 walks and 17 strikeouts in 28 games.

During the early stages of his pro career, Murphy  struggled with receiving the ball and throwing out runners, while also dabbling with the idea of playing third base. He turned the corner in his development behind the plate in 2012 with his success rate at gunning down base runners jumping to more than 30 percent for the first time. So far in 2013, he's just shy of throwing out 50 percent of baserunners while playing at Double-A, one step ahead of his fellow catching prospect.

The talent evaluator who spoke with MLBTR said the Yankees organization thinks very highly of Murphy. "Due to his diligence, ability and the focused hard work of our coaches, he has become a defensive plus. He is on track to become a quality major league catcher," he said. "He receives the ball well and is an above-average thrower. He has the intelligence and game awareness to manage a game at the major league level."

Currently in his fifth pro season, Murphy will need to be added to the 40-man roster by the November deadline to be protected from the annual Rule 5 draft. If added, he'll be granted three option years that will allow him to be shuttled between the majors and the minors during that time frame.

Houston Astros

The 10th overall selection in the 2008 amateur draft, Jason Castro's career development has been slowed by trips to the disabled list. In fact, he lost the entire 2011 season to a serious knee injury. Perhaps hampered by the lost playing time, the Astros' starting catcher's offense has not developed as hoped. Still just 25, the Stanford alum has time to jump-start his bat, but Houston has accumulated some solid catching depth in the past year.

Acquired last year from Toronto in a 10-player deal that sent J.A. Happ and two other pitchers to Toronto, catching prospect Carlos Perez has enjoyed the change of scenery. After spending five years in Rookie ball and Low-A ball with the conservative Blue Jays player development program, the Astros loosened the reins on the young player and he responded favorably. In less than a year, the 22-year-old Venezuela native reached Triple-A and is hitting above .300 while playing steady defense. Houston will almost certainly want to protect him prior to this year's Rule 5 draft at the Baseball Winter Meetings.

Tyler Heineman flew under the radar a bit as an eighth round draft pick out of the University of California, Los Angeles in 2012. Since signing, though, he's done nothing but hit. The switch-hitter posted a .352 batting average with 26 walks and 12 strikeouts in 55 games during his short-season debut last year. Jumped all the way to High-A to open 2013, Heineman has hit .329 with just eight strikeouts in 23 games.

Not flashy and with below-average power, the catching prospect shares a similar profile to that of seven-year big leaguer Ryan Hanigan of the Reds. The big challenge for the backstop is to continue polishing his defensive skills to meet the high standards set at the big league level. Time is on Heineman's side as he doesn't have to be added to the 40-man roster until after the 2015 season, which would then buy him three option years.

Toronto Blue Jays

The Blue Jays opened the 2012 season with the most impressive collection of catching depth in baseball with J.P. Arencibia at the major league level and a plethora of impressive prospects including d'Arnaud, Yan Gomes, Perez, A.J. Jimenez, and Santiago Nessy. Since midway through the 2012 season, Toronto has traded away d'Arnaud (Mets), Gomes (Indians) and Perez (Astros) in an effort to improve the pitching depth at the big league level.

The two remaining catchers have the talent to be considered among the club's Top 10 best prospects. Unfortunately, both have also been bitten by the injury bug. Jimenez blew out his elbow during the 2012 season and underwent Tommy John surgery. The club has been cautious with him in 2013 and he's already missed a little time after experiencing soreness in his surgically-repaired elbow. Nessy received his first full-season assignment in 2013 and was off to a respectable start before suffering a concussion while trying to breakup a double play at second base. He has plus raw power and has made huge strides on the defensive side of his game.

Prospect Tidbits: Seattle's Zunino was considered the cream-of-the-crop when it came to eligible catching prospects in the 2012 amateur draft. Fast forward to 2013 and the University of Florida alum has already reached Triple-A. Two other highly-drafted catchers from 2012 are making names for themselves with solid play so far this season.

Perhaps the hottest hitter in the South Atlantic League, the Mets' Kevin Plawecki (drafted 35th overall) is currently hitting .374 through 35 games in Low-A ball. He's also flashed power with 25 of his 49 hits going for extra bases. If he keeps up this pace, a promotion to High-A or Double-A should be in the cards. Rockies catching prospect Tom Murphy (third round) has appeared in only 24 games thanks to a brief visit to the disabled list, but he's hitting .357 with 17 of his 30 hits going for extra bases. Like Plawecki, Murphy is probably too advanced at the plate for Low-A ball.

Another 2012 draft pick, Josh Elander, attracted attention as a second- or third-round talent as a college catcher but questions surrounding his ability to stick behind the dish caused him to slide to the sixth round where he was nabbed by the Atlanta Braves. After catching briefly in 2012, the prospect was moved out from behind the plate and has played 31 games in left field in 2013. The move has certainly agreed with his offense, as he's hitting .314 with an above-average power output.
