The first thing that stands out on this list is that if you’ve going to be a big catcher, you’d better be able to hit. Lombardi and Mauer are the only two catchers to win multiple batting titles, and McCann is a six time all-star and five-time silver slugger. Wieters just made his first all-star team, and even Pierzynski has made two of them and is just a tick below league-average, which for a catcher makes him above average. Long story short, if you don’t give your team a bunch of offensive performance, you’re not sticking behind the plate.
The good news is, Montero can hit. A lot. The bad news is that none of these guys really make for very good comps for Montero.
Pierzynski, Mauer, and McCann are all left-handed and Wieters is a switch-hitter. Handedness is very important when making a good comp. Lombardi was a great hitter, but didn’t hit for much power. Montero doesn’t necessarily project to win a batting title, but he almost certainly will hit for power. McLean didn’t hit much at all, and Buck hasn’t had anywhere near the prolonged success that is projected for Montero. Back to the drawing board.
We need to lower the size requirements. Let’s face it, there just hasn’t been a player like Montero, at his size, to catch regularly, which may be an indicator that it may never happen, but remember, we’re still trying to formulate our best-case scenario. The Yankees let Montero keep catching all the way through Triple-A, so there is at least some possibility that he’s able to pull it off for his younger years.
If we change the requirements to 6'1" and 215 pounds, and lower the playing time requirements to 100 games and at least half at catcher, we get a much longer list. The catchers to do it in more than four seasons were Charles Johnson, John Buck (again), and Joe Oliver. In fact, the only player on the list with any sort of sustained success is Johnson, and he was a defensive wizard who had only one season that approaches what Montero is expected to do offensively.
What we're learning is that there simply haven't been any catchers with Montero's build that have either been able to sustain a long career behind the plate, or have been able to be strong offensive players while attempting to pull it off.
So let's forget the weight for a minute. It's not something we can just disregard altogether, but it's also not like saying "let's forget that he's slow and predict him to steal 40 bases a season.". Montero is a big boy, but every year in every sport we see players who are bigger and faster than their contemporaries who have the same athleticism as players years before that we're a fraction of their size. In our best- scenario, let's make this assumption for Montero, who by all reports is a pretty good athlete for his size.
So we will just stick with tall catchers, not necessarily heavy ones. But now we're going to add in some performance barriers. Of seasons for catchers who were at least 6'2" and met the same playing requirements as before, but batted at least .300 and hit at least 30 home runs in the expansion era, we found that we have 11 examples. Mike Piazza had eight of them.
Damn he was good.
The other three men each did it once - Javy Lopez, Charles Johnson, and Joe Torre.
So after all that, it looks like our best comp may be Piazza after all. Just because our initial instinct was right, doesn't mean this wasn't worth the effort.
But I'm not comfortable with a complete Piazza comp. After all, Piazza had a three-year stretch where he hit .336, .346, .362 and never struck out more than 93 times in any season is entire career. Piazza's 9 seasons of 30-plus home runs may be within reach for Montero, but he's not regarded as nearly the same type of contact hitter as Piazza.
And then there's the defense.
I don't know whether it's because it's a different era where offense is down and defense matters more, or if Montero is just that much worse defensively, but Piazza was able to stay behind the plate his whole career. I just don't see Montero being back there anywhere near that long. Almost no one has ever done it at his weight, and the few who have weren't able to sustain any long-term offensive success while they did it.
So after all that, what's our best case scenario for Montero? A post-steroid version of Mike Piazza for the first four to five years of his career, but spending almost as much time at DH as catcher before making the shift permanently. I'm much more comfortable with the Piazza comp when we add in he extra caveats.
But, in truth, even four to five years of catching 75 or so games a year for Montero may be optimistic. So let's look for a purely offensive comp for our high-end realistic comp, since his only predictable move is to DH.
Now that he’s on the Mariners and people expect him to be their next great DH, the obvious comparisons to Edgar Martinez will about this spring. Please disregard them. Martinez won two batting titles, hit over .330 four times, and most importantly, walked over 100 times in a season four straight years from 1995-98. Montero has never exhibited that type of plate discipline in the minors, never walking more than 46 times in a season. Martinez also only hit more than 30 homers one in his career, while Montero should be able to surpass that mark with regularity.
So in looking for his best offensive comparisons, I searched for right-handed hitters of any position that had the most seasons hitting over .300 with an on-base percentage of less than .375, more than 25 homers in a season and more than 35 doubles, all reasonable projections for Montero’s prime. Below are the players since 1961 who have had more than one such season.
