Rarely is OPS (on-base percentage plus slugging percentage) a fantasy stat. It’s off many people’s radar but it’s widely available and closely mimics a position player’s overall hitting talent. While other stats (e.g. wOBA and wRC+) also give a hitter an overall value, these stats aren’t available at every website. Most sites have their own unique blend but OPS is commonly available. Because of this availability, I’ve been using it as a baseline in recent articles on adjusting projections based on prospect pedigree and when hitters get platooned ($$). Now, it’s time to use OPS to help predict the individual categories.

The process I used for this study was to simply see how much various stats changed when OPS changed a certain amount. For rate stats (e.g. batting average) the conversion is straightforward. For counting categories, I put the stats on a per 600 plate appearance scale. Additionally, I only compared data from 2015 to 2017 during the current “juiced” ball era. I know the process is not close to being 100% precise and that is fine. I’m just trying to create general adjustments and can look to hone the process later. I’m putting in 20% effort to get 80% of the answer.

My current aim in fantasy baseball is to find instances where player evaluations can be improved. With several prospects recently getting called up, I am trying to answer the simple question: is there any projection information to be gained from being a highly touted prospect. The short answer is yes, but it took me a while to get good results.

I wanted to keep the analysis simple so I used all available Steamer projections which to back to 2010. Additionally, I used Baseball America’s top 100 ranked prospects for that time frame. From these two data sets, I compared the hitter’s projected results to the actual results for their first few seasons.

I’m of the belief that there is a group of similarly talented players who owners should keep churning to find the latest true breakout. Lewis Brinson (64% FanTrax ownership) and Jacoby Jones (24% owned) are two such players. While Brinson was part of the draft endgame with a 275 NFBC ADP, Jones was waiver wire fodder in almost every league with an ADP of 660. If given the option, I’d gladly own Jones right now.

What’s wrong with Lewis Brinson?

Brinson has been a highly touted prospect for several seasons with Baseball Prospectus having him on their Top-101 back in the 2013 but he jumped onto all major lists starting in 2016.

On Friday, I examined hitters with new plate approaches focusing on launch angle and plate discipline. I notice Brad Miller, Javier Baez, and Leonys Martin had each dropped their groundball rate but I didn’t have an idea of what is the ideal value. After spending way too much going down way too many paths this past weekend, the simple answer is average 20 degrees (32% GB%) with weak and/or fast hitters needing to push the value down to 15 degrees (42% GB%).

There is no need for readers to hang around any longer if they have more pressing matters like setting their daily or weekly lineups. For those looking for a little more explanation, thanks for staying around. I went through several methods I’m not going to discuss. I like simple useable answers and that’s what I’ll provide today.

With the season underway, owners need to start adjusting some player’s fantasy value. Some of the tweaks can be from talent changes (e.g. increase in talent) or role (e.g. moving for a long reliever to starter). Three players, Kenley Jansen, Trea Turner, and Luke Weaver, are three such players on the move.

This past weekend I was again honored to be asked to participate in the 15-team Tout Wars auction held bright and early on Saturday morning at Staten Island’s Richmond County Ballpark. After a short ferry ride, I caught up with old friends and then auction began. Like last year, it rolled at a fast pace and ended in about four hours later. While my final team’s roster doesn’t resemble any team I’ve previously rostered, it has a nice chance to compete.

Prep

The biggest decision I made when constructing this team happened months ago when I looked back at my 2017 fantasy teams and found my pitching way outperforming my hitting.

To help offset this final imbalance, I decided to go with a 70%/30% hitter/pitcher split. Over the past few seasons, this league’s split has been 67.8%/32.2%. The difference works out to a $6 difference. I am not married to reaching this exact mix at the auction but it gives me a general guideline to follow. It had a side effect I didn’t fully understand but the anomaly ended up driving my auction.

What’s up, FanGraphs!  My name is Derek Carty.  If you’ve been into sabermetrics long enough, perhaps you recognize me from my time managing the fantasy sections for Baseball Prospectus and The Hardball Times a while back.  The past half-decade or so I’ve been focused solely on daily fantasy sports, most notably with ESPN.com, Baseball Tonight, RotoGrinders, and on Twitter (@DerekCarty).  I’m so pumped to be announcing today that I’m getting back involved publicly on the sabermetric side (privately, I never left!) by integrating my projection system, THE BAT, into the offerings here at FanGraphs!

This means we’re actually getting close to official baseball, right? It’s bold prediction season and you know the drill (with an Ottoneu context), so let’s get started.

The 2018 Pod Projections are now available! For the first time, the package includes NFBC ADP, along with all historical Pod-developed xMetrics. My projections are based on the methodology shared in my eBook Projecting X 2.0, and the process continues to evolve and improve (thanks Statcast!).

Last week and earlier this week, I highlighted a group of hitters who my Pod Projections projected stolen base upside and stolen base downside compared to Steamer projections. Until I performed the comparison, I had no idea I was so bearish on steals, relative to both Steamer and to 2017.
