MLB Playoffs: Key relievers to watch for each team - Beyond the Box Score

I still see Musgrove as a starter. The problem I saw was he was in the strike zone too much. The confidence gained in the bullpen might be the jump he needs to become an effective starter. Next year.

Joe Musgrove, RHP, Houston Astros

Musgrove underwhelmed as a starter early this season, posting a 6.12 ERA over 72 innings. But a move to the bullpen has invigorated Musgrove, as he’s posted a 1.44 ERA with a 21.7 percent strikeout-minus-walk rate in 31.1 relief innings.

Struggling starter turned shutdown reliever: it’s a story seemingly as old as time itself. But just because this is a trite tale doesn’t make it any less impactful. The reliever version of Musgrove is adept at getting strikeouts and groundballs, posting a 51.9 percent groundball rate as a reliever. And, you guessed it, can do it over multiple-inning stints.

The Astros bullpen is one of the best ones remaining, despite their inability to find a reliable left-hander. Having an option like Musgrove to pitch in front of Chris Devenski and Ken Giles makes the Astros bullpen a formidable one, lefty or no lefty.

Chad Green on His Overpowering Repertoire

Chad Green’s 2-0 win-loss record and 2.05 ERA suggest he’s had a successful season. Those numbers only begin to tell the story. Pitching out of the New York Yankees bullpen, the 26-year-old right-hander has allowed just 27 hits in 57 innings while also recording 86 strikeouts…

“[The coaching staff] probably saw that I had a high spin rate, so they said, ‘OK, let’s try throwing more fastballs up in the zone.’ I’d say I probably learned about my spin rate around the middle of the year, after a couple starts in Triple-A.

How Promotions and Demotions Affect Relief Performance – The Hardball Times

I am struck by the fact that all groups outperform their projections on average. I suspect this fact has more to do with the projections themselves and doesn’t mean there’s a hidden pattern here we’re not seeing. If anyone has suggestions for other projection mechanisms that would be suitable, let me know in the comments.

The conclusion here seems straightforward. I can find only the most tenuous connection between a role change for a reliever and his subsequent performance on the field. If a reliever does struggle or suddenly become lights out, look for other factors besides his recent promotion or demotion.

Our 2017 Goose-Egg Reliever Rankings Are Here

But as Ben Lindbergh recently documented over at The Ringer, the hegemony of the save may have loosened just slightly. So far this year, the Cleveland Indians’ Andrew Miller — who might be the American League’s best reliever — has made five appearances that stretched over multiple innings. Miller, who has yet to allow a run on the season, doesn’t have any saves. But he does have 10 goose eggs, tying him for third in baseball. (All statistics in this article are accurate through the end of May 4.)

Even more encouraging is the case of the Astros’ Chris Devenski. He has pitched a Gossage-like 18.1 innings over eight appearances so far this year. (In 1975, when Gossage set the single-season record with 82 goose eggs, he pitched 141.2 innings over 62 appearances.) Devenski has only one save, but he has 10 goose eggs. With an exceptional ratio of 34 strikeouts against just two walks on the season, he has grown more comfortable with his multi-inning role. If the Astros keep moving him up their pecking order — Devenski has been used in some high-leverage situations so far, but also some medium-leverage ones — he’ll be a candidate to finish with 50 or even 60 goose eggs. No pitcher has reached the 60 goose-egg benchmark since Scot Shields in 2005.
