Bullpen spending is not a good measure of team attention paid to or methodology in crafting a strong, deep bullpen. Mostly because pen spending is by far most significantly tied to shelling out for a pricey closer.
I'm assuming that the previously cited pen $$$ numbers are coming from this Spotrac link:
MLB Relief Pitcher Spending - Cap
There are 10 teams spending more than the league average of $13.1m in their bullpen:
1) The Mets are at a whopping $39m. But $30m of that is from shelling out big closer bucks to Jeurys Familia, Edwin Diaz, and Trevor May in free agency in a desperate attempt to stabilize the back of their pen as each man has faltered at various points with this team.
2) The Dodgers are at $35m, but $20m of that is on Kenley Jansen. Another $13 or so is from two other former closer pickups in Blake Treinen and Corey Knebel. And the rest of their pen is making less than a $1m apiece
3) The Yankees are at $32, but almost $28 of that is doubled down closer money on Chapman and Britton. Then there's Chad Green and a bunch of value deals
4) The Red Sox $29m tag is steep because their current pen listing includes the starter money that was handed to failed rotation pieces Garrett Richards and Martin Perez. Adam Ottavino and Matt Barnes are their only notable money relievers at a combined $12m and Barnes isn't even making
that much.
5) The Braves check in at $27m but $13m of that is on Will Smith. Another $7m on Chris Martin, and everyone else is $2m or less
6) The White Sox are spending $23m, but almost $17m of that is from the recent acquisitions of Kimbrel and Hendriks, both closers.
7) The Angels ($21m) are giving $9m closer money to Raisel Iglasias and have $7m tied up in the shambling corpse of Jose Quintana and that's more than 2/3rds of their pen budget right there.
8) Houston may have cut some costs out of their pen, but Ryan Pressley is making $8.75 as the closer, Pedro Baez makes $4.75m, and no other reliever makes more than $2m out of their $19m pen.
9) The Phillies ($15.7m) are kind of awkward because their closer is bargain bin Ian Kennedy. They gave Hector Neris $6m likely for his closer history and $7m to Archie Bradley I guess because he's decent and has high 1st round pick pedigree. Matt Moore is in this list but he's been a starter more than a reliever for the Phils.
10) St. Louis is paying out $14.7m but $12m of that is on Andrew Miller's 3-year closer money pact that he's never come close to justifying (and probably shouldn't have received in teh first place)
Of those 10 teams the only ones who aren't inflating their price tag based on big pricey closer money are the Red Sox (whose pen spending is based on sticking with junk starters in relief roles) and sort of the Phillies but not really. Every other team has a high pen budget because they've spent it on "proven closers" to varying degrees of success. Of this top 10 spenders, the Yankees, Dodgers, White Sox, Red Sox, and Mets are the only teams also in the top 10 in bullpen fWAR. The Astros, Angels, and Phillies are all in the bottom half of the league in spite of their spending.
Consider also the fact that the Jays' current $6.8m is mostly on account of Brad Hand and his $3.75m price tag, but that's the pen as it stands now. Add back Joakim Soria's $3.5m and they're right around the league average in bullpen spending. But also, what if they had the pen they started the year with?
The opening day roster's pen was Romano, Dolis, Borucki, Chatwood, Phelps, Merryweather, Mayza, Thornton, Payamps. Let's take out Payamps and add back Kirby Yates.
The cost of that pen would've been:
Romano: $584k
Dolis: $1.5m
Borucki: 595k
Chatwood: $3m
Pehlps: $1.75m
Merryweather: $578k
Mayza: $600k
Thornton: $485k
Yates: $5.5m
That would've been about $14.6m, which would've slotted them in right on the heels of the Cardinals who are listed above at 10th in the league. But that group collectively has only provided 2 good relievers for the season in Romano and Mayza, 3 hurt ones in Phelps, Merryweather, and Yates, 1 inconsistent one in Borucki, and 3 tire fires in Dolis, Chatwood, and Thornton.
Spending big bucks on your pen is not a path to success. Largely because spending big bucks is usually because you're giving out sacks of cash to a name brand closer (which the Jays don't need. Romano has been solid). And because bullpens are so weird and random that you're more likely to get burned giving out money to guys who are always potentially replaceable than you are to see value on it. Had they made the trades they made in season for Richards and Cimber and Soria (and Hand I guess) earlier in the year it probalby would've been better. But they also needed some breaks. If even 2 of the walking wounded pen arms had stayed healthy things could've been much different. Consider an 8-man pen of:
Yates
Romano
Merryweather
Cimber
Richards
Mayza
Snead/Saucedo
Some random long-man, it doesn't matter.
That top 6 would be really good and cover you in a lot of situations.
