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:

0.322 — Dee Gordon batting against Seth Lugo
0.319 — Jean Segura batting against Martin Perez
0.315 — Elvis Andrus batting against Mike Leake
0.311 — Adrian Beltre batting against Mike Leake
0.305 — Charlie Blackmon batting against Johnny Cueto
0.303 — Marcell Ozuna batting against Seth Lugo
0.303 — Robinson Cano batting against Martin Perez
0.301 — David Peralta batting against Travis Wood
0.301 — Gerardo Parra batting against Johnny Cueto
0.300 — Alex Presley batting against Daniel Gossett

It looks like the Rangers at the Mariners should produce ample opportunities for hits.

Here is how the NN with Park ranks the players:

0.322, 0.748 — Dee Gordon batting against Seth Lugo.
0.305, 0.743 — Charlie Blackmon batting against Johnny Cueto.
0.267, 0.741 — Jose Altuve batting against Lucas Giolito.
0.294, 0.740 — Daniel Murphy batting against Luiz Gohara.
0.319, 0.738 — Jean Segura batting against Martin Perez.
0.296, 0.734 — DJ LeMahieu batting against Johnny Cueto.
0.301, 0.732 — Gerardo Parra batting against Johnny Cueto.
0.315, 0.732 — Elvis Andrus batting against Mike Leake.
0.311, 0.729 — Adrian Beltre batting against Mike Leake.
0.295, 0.728 — Avisail Garcia batting against Collin McHugh.

Gordon is hot, with eight hits in his last three games, and hits in 15 of 16 games he played in September. Blackmon and Segura are tied for consensus second 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:
