Group 2: The Mariners could get a good reliever that was once great.
No, Miller isn’t the guy who made waves in the mid-2010s with one of the most dominant runs we’ve seen by a reliever. From 2013-2017 he had a 1.82 ERA, 1.96 FIP, an ERA+ of 234, and a K rate of 14.5/9. He isn’t that guy anymore.
You know what though? He’s still good.
Over the last four years, he’s got a 4.31 ERA with an 11.2 K/9. It’s not stellar, but he’s still fun to watch and if things work out, would be a steal. A small deal for the 37-year-old with incentives could easily be a win/win for the Mariners and Andrew Miller.
Diekman had an amazing all-time 2020 season. 21.1 innings and one earned run, with just eight hits and a 13.1 K rate. Other than that, he’s been a high 3 ERA guy with a good K rate. I almost put him up above, but a rough 2019 and a bad 2018 convinced me to keep him down in group two. He did have awful luck with BABIP those years (.331 and .319).
His numbers may be a little better than they look, as he has a FIP of around 3.40 for his career, and a stronger strikeout rate as he’s gotten older, up to 12.5-13.0 per 9.
Hey, that’s the guy the Mariners had in 2021. Yeah, they could bring him back, and I wouldn’t mind it at all. He hasn’t been as good as he was prior to 2019 but is still solid. He had a bad two-game stretch in Seattle where he gave up five runs in two innings. Other than that, he gave up just one run through nine appearances and 9.1 innings.
Which one of these guys would you most want the Mariners to go after? It would be nice to see them add another dominant piece to the bullpen, giving them a chance to have one of the best compilation of arms we have seen in quite some time.
