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:

0.333 — Xander Bogaerts batting against Kyle Gibson
0.311 — Dustin Pedroia batting against Kyle Gibson
0.311 — Justin Turner batting against J.C. Ramirez
0.311 — Corey Dickerson batting against Jameson Taillon
0.308 — Jon Jay batting against Joe Ross
0.307 — Yadier Molina batting against Patrick Corbin
0.303 — Jedd Gyorko batting against Patrick Corbin
0.302 — Aledmys Diaz batting against Patrick Corbin
0.302 — Jose Ramirez batting against Andrew Cashner
0.301 — Mookie Betts batting against Kyle Gibson

I haven’t see Bogaerts high on the list in a while. This June seems to be an all or nothing month for him with 10 multi-hit games, and nine oh fors. In general, it looks like a good day to pick a hitter from the Red Sox or the Cardinals. Molina own the longest current hit streak at 14 games.

Here is how the NN with Park ranks the players:

0.333, 0.753 — Xander Bogaerts batting against Kyle Gibson.
0.297, 0.749 — Daniel Murphy batting against Jon Lester.
0.295, 0.740 — Jose Altuve batting against Daniel Gossett.
0.311, 0.737 — Justin Turner batting against J.C. Ramirez.
0.311, 0.736 — Corey Dickerson batting against Jameson Taillon.
0.302, 0.733 — Jose Ramirez batting against Andrew Cashner.
0.311, 0.731 — Dustin Pedroia batting against Kyle Gibson.
0.301, 0.720 — Mookie Betts batting against Kyle Gibson.
0.307, 0.720 — Yadier Molina batting against Patrick Corbin.
0.288, 0.716 — Michael Brantley batting against Andrew Cashner.

Bogaerts makes the top of this list as well, making him the unanimous pick. Murphy was just off the other list, tied for 11th. Like most of the Twins, Gibson pitched better on the road this year, allowing a .364 BA at home, .265 away. Both BAs in those situations are still small sample sizes. Murphy is 1 for 6 career against Lester as he tries to extend his hit streak.

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