Let’s imagine that Jacob deGrom is pitching for the New York Mets and has just faced the number nine batter his second full time through the order. Let’s also imagine, and this one is hard to do, that deGrom isn’t himself this fine day and shouldn’t go through the order a third time. Manager Luis Rojas pulls a hot dog style folded paper out of his back pocket and looks at multi-colored charts, doodles, heat maps, and whatever analytical imagery made its way into tonight’s report. Could the image below ever make its way onto that paper?

NEW FEATURE ALERT! We have added an upgraded version of RosterResource’s Closer Depth Chart to FanGraphs. Read more about it here.

We will always include a link to the full Closer Depth Chart at the bottom of the Bullpen Report each day. It’s also accessible from the RosterResource drop-down menu and from any RosterResource page. Please let us know what you think.

The 2021 version of Bullpen Report includes five different sections, as well as the closer chart, which can be found at the bottom of the page.

1. Notable Workloads: Primary closers or valuable members of a closer committee who have been deemed unavailable or likely unavailable for the current day due to recent workload.
2. Injury News 
3. Outlier Saves: Explanation for a non-closer earning a save during the previous day.
4. Committee Clarity: Notes on a closer committee that clarify a pitcher’s standing in the group.
5. Losing A Grip: Struggling closers who could be on the hot seat.

The “RosterResource” link will take you to the corresponding team’s RosterResource depth chart, which will give you a better picture of the full bullpen and results of the previous six days (pitch count, save, hold, win, loss, blown save.)

If I were to look into the rear-view mirror while riding in the back seat of an Uber and ask the driver, “Could you tell me the expected time of arrival, minus the current time please?”, I would probably get some weird looks. But, if I were to ask you, fantasy baseball enthusiast, for your team’s current stolen base total, plus your rest of season (RoS) projected stolen base count, you would probably be delighted. It would give you a good sense of where your team is and where your team is heading.

Eno Sarris said not to look at HR rate. He said it and I’m going to listen. However, FIP and xFIP are not HR rates, and I’m going to look at that. Too often we assume that others know, or we actually know, what a statistic represents. We hear it, we think it, we know it. But, take a moment with me to reinvigorate our understanding of these two very important statistics.

FIP gives us an idea of how a pitcher performs regardless of who is playing defense behind him. It accounts for strikeouts, walks, hit by pitches, and home runs allowed. FIP gives us a better understanding of how a pitcher is performing than ERA. xFIP tells us all the same but accounts for the volatility of the HR rate. Quoting from our very own FanGraphs glossary, xFIP is:

calculated in the same way as FIP, except it replaces a pitcher’s home run total with an estimate of how many home runs they should have allowed given the number of fly balls they surrendered while assuming a league average home run to fly ball percentage (between 9 and 10% depending on the year).

There have been some really exciting starts from young pitchers so far this season. On Sunday, Michael Kopech pitched five innings, faced 18 batters, and struck out 10 of them. When I saw that he was starting in place of Lucas Giolito on Sunday morning, I totally rolled the dice and got lucky. Adding a young pitcher who I’ve been rooting for over the past few years and it paying off was great. But, I’ll admit, it made me feel a little empty inside.

As I stared at the tv and excitedly encouraged whiff after whiff I slowly began to realize that a win wasn’t going to be possible. I knew Kopech would be on a pitch count and I knew he wasn’t going to suddenly become a rotation mainstay, but I went for it anyway, dropping a set-up reliever in order to gain some strikeouts. I felt oh-so-sad when Tony La Russa effectively looked into the camera and told me not to get used to it. Monday morning had me reflecting, was it worth it? Which is better to roster, low-pitch count starters like Kopech or middle/set-up relievers?

Let’s get a disclaimer out of the way; I’m not writing to recommend a punt and I don’t think you should just completely give up on a category. Ok? All I’m saying is if I were to punt, here’s how I’d do it. Punting in fantasy baseball is when you abandon a category. Saves are hard to come by and you might just be able to completely forego accumulating them. Many fantasy managers will draft with the punt in mind straight from the get-go. Some will wait and see how their team is shaping up and will punt a category that is lacking. Surely there has been work determining the value of the punt, Ron Shandler’s forecaster comes to mind. But let’s look at it from a 2021 perspective and whether or not it’s theoretically possible to punt a category and also win your league.
