Mariners Report Cards: Outside of the big bullpen names, how did the rest of the pen do in 2023?

With report cards out already on the big names in the Mariners pen, it's time to look at how the rest of the pen did in filling innings for the Mariners

We've already looked at the big names from the Mariners bullpen and given them grades for the 2023 season. Brash, Munoz, Topa, and Speier all had a big enough impact and threw enough innings that it was worth taking a look at their seasons individually to give them grades. For the remainder of the bullpen, somewhat similar to the combined article about Ray/Flexen/Marco, we will be putting it all into one and giving them a collective grade.

First, let's take a look at everyone who threw in the pen this year, just to get an idea of who took up innings for the Mariners. Sewald won't be in here either, since we wrote a dual article on both his grade on the year, and the Mariners return in the trade. Also, anyone who threw five or fewer innings has been combined into one slot at the bottom. That would include Bukauskas, Ryan, Berroa, Ford, Sweet, Rodriguez, and McCaughan.

So, when it comes down to it, the "big" names for the Mariners threw a total of 227 innings with a 3.529 ERA and a 1.264 WHIP. It gets even better if you pull out Diego Castillo, down to 3.421 ERA and 1.250 WHIP. That's pretty darn good. What it's showing is that, as a whole, the Mariners were able to throw out someone with a better ERA than Speier had this year. A 1.0 WAR reliever (or so) as the remainder of your bullpen after your top 4 guys, and that's after Sewald leaves.

I give the rest of the Mariners bullpen a B+ on the season for their 2023 report card

You've definitely got some stinkers on there, as well as a big smattering of walks from a handful of guys. They weren't afraid to send Diego down though, and let Weaver go after only a handful of outings. They showed a willingness to try and adapt, which doesn't always happen. However, those blips can still affect games, making them closer than they should or causing the tide to turn completely.

It was still impressive, and I think they did a darn good job as the end of the bullpen. It might even be an A-, and I think I would listen to that argument if it was made.
