Beat the Streak Picks

Here are the top picks my programs produced for use in Beat the Streak. This post mostly explains the ideas behind the calculations. In addition, this post shows tests on the Neural Network (NN). This post discusses an NN that includes the ballpark. I recently updated the models, and the results of those tests are here.

For 2017, I am just going to publish the Log5 hit averages and the NN probabilities with parks factored in. I am keeping track of the results here. I added a graph that gives a visual representation of the probability and success each day. The sheet also includes a table that summarizes the length of positive and negative streaks.

First, the Log5 Method picks:

0.330 — Charlie Blackmon batting against Patrick Corbin
0.323 — Gerardo Parra batting against Patrick Corbin
0.322 — Jose Altuve batting against Tyler Skaggs
0.320 — Elvis Andrus batting against Mike Leake
0.320 — DJ LeMahieu batting against Patrick Corbin
0.316 — Jean Segura batting against Martin Perez
0.316 — Adrian Beltre batting against Mike Leake
0.309 — Nolan Arenado batting against Patrick Corbin
0.302 — Avisail Garcia batting against Eric Skoglund
0.302 — Robinson Cano batting against Martin Perez

Corbin is a rare pitcher, one with a high strikeout rate that also allows a high batting average.

Here is how the NN with Park ranks the players:

0.322, 0.766 — Jose Altuve batting against Tyler Skaggs.
0.330, 0.760 — Charlie Blackmon batting against Patrick Corbin.
0.320, 0.750 — DJ LeMahieu batting against Patrick Corbin.
0.323, 0.747 — Gerardo Parra batting against Patrick Corbin.
0.290, 0.739 — Daniel Murphy batting against Luiz Gohara.
0.320, 0.739 — Elvis Andrus batting against Mike Leake.
0.316, 0.737 — Jean Segura batting against Martin Perez.
0.316, 0.735 — Adrian Beltre batting against Mike Leake.
0.295, 0.733 — Dee Gordon batting against Aaron Nola.
0.309, 0.732 — Nolan Arenado batting against Patrick Corbin.

Altuve pops to the top as usual, but Blackmon is the consensus first choice.

As always, your best pick will fail to get a hit about 25% of the time.

Here is the daily list of active streaks of plate appearances without a hit, with pitchers eliminated:
