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 update 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.

First, the Log5 Method picks:

0.292 — Starlin Castro batting against Rick Porcello
0.287 — Daniel Murphy batting against Tyler Chatwood
0.285 — Zack Cozart batting against Wily Peralta
0.284 — Cesar Hernandez batting against Edinson Volquez
0.283 — Brandon Phillips batting against Noah Syndergaard
0.279 — Eugenio Suarez batting against Wily Peralta
0.277 — Jonathan Schoop batting against Alexander Cobb
0.277 — Corey Seager batting against Johnny Cueto
0.275 — Adam Jones batting against Alexander Cobb
0.275 — Jacoby Ellsbury batting against Rick Porcello

I have to say I’m a bit surprised to see two Yankees making the top ten against the 2016 AL Cy Young Award winner. Then again, in two of the last three seasons (counting 2017), Porcello allowed a fairly high batting average with few walks, the type of pitcher who should produce a high hit average. I’m more surprised to see Ellsbury than Castro on the list, since Ellsbury was not that good a hitter the previous two seasons.

The NN with Park modifies the list like this:

0.287, 0.733 — Daniel Murphy batting against Tyler Chatwood.
0.274, 0.712 — Jose Altuve batting against Trevor Bauer.
0.283, 0.709 — Brandon Phillips batting against Noah Syndergaard.
0.266, 0.708 — DJ LeMahieu batting against Tanner Roark.
0.292, 0.704 — Starlin Castro batting against Rick Porcello.
0.277, 0.703 — Corey Seager batting against Johnny Cueto.
0.264, 0.700 — Trea Turner batting against Tyler Chatwood.
0.268, 0.700 — Jean Segura batting against Daniel Norris.
0.284, 0.700 — Cesar Hernandez batting against Edinson Volquez.
0.259, 0.699 — Mookie Betts batting against Luis Severino.

Note that the NN agrees with me on Ellsbury, as it drops him way down the list with a probability of a hit int he game at .672. Daniel Murphy appears to be the consensus pick, with Starlin Castro second. As always, your best pick will fail to get a hit about 25% of the time.

Here is the latest list of players that currently have the longest streak of plate appearances without a hit:
