Salvador Perez, Kansas City Royals
2013 Stats: .263/.277/.375, 1 HR, 8 RBI, 6 R
The 22-year-old catcher out of Venezuela turned heads in 2012 by posting a line of .301/.328/.471 and slugging 11 HR and 39 RBI in 76 games.
After numbers like that in 2012, it's hard to imagine Salvador Perez simply being average. RoyalsReview.com writer Connor Moylan says that Perez still needs to adjust his approach at the plate before he can truly have a breakout year that will solidify him as a top catcher in the league.
Jonathan Lucroy, Milwaukee Brewers
2013 Stats: .233/.278/.397, 3 HR, 12 RBI, 7 R
Jonathan Lucroy is coming off of a stellar 2012 campaign where he posted a line of .320/.368/.513 with 12 HR and 42 RBI. At the ripe age of 26 it appeared that Lucroy was breaking into his prime and would be poised for an even better 2013 season.
He's gotten off to a decent start to the season at the plate, but it has only been a glimmer of the talent he displayed last season. Lucroy is definitely one of the catchers to keep an eye on as the season progresses due to his natural ability at the plate.
Much like the other two catchers mentioned so far, Lucroy has the ability to crack the top 10 catchers in the league and demonstrate his full potential.
John Buck, New York Mets
2013 Stats: .250/.279/.575, 8 HR, 23 RBI, 14 R
There is no denying that John Buck is slugging with the best of the MLB right now; however, it won't last all season long. Right now, Buck is averaging a home run every 10 at-bats, which is a sensational stat, but it won't last too long.
As Yahoo! Sports points out, Buck has already began cooling down, and his home run numbers should take a significant dip in May compared to April. He hit only 12 long balls in 2012 and has never topped 20. He is showing a lot of pop right now, but fans should be weary and not overrate Buck.
Victor Martinez, Detroit Tigers
2013 Stats: .198/.272./.242, 0 HR, 9 RBI, 5 R
Up until now, Victor Martinez would have found his place ranked highly on this list. He has been an elite hitter for years, as baseball-reference.com shows that he has a career OPS of .833, meaning he draws walks and can slug with the best of them.
After tearing his ACL and missing the entire 2012 and stumbling out of the gate in 2013, it appears that Martinez may have some lingering issues with the injury that are stagnating his game. Also, at the age of 34, he is leaving his prime. Those two factors combined don't bode well for Martinez. A return to hitting prowess is still possible from Martinez, but that would likely come as a first baseman or a designated hitter.
It appears that his days as a catcher are numbered.
