Expected wRC+ for the Cape Cod League 2. Today’s MLB.TV Free Game 3. Today’s Complete Schedule Expected wRC+ for the Cape Cod League Regarding What This Is What follows is a so-called Expected wRC+ Leaderboard for the very prestigious Cape Cod Baseball League of Cape Cod, a summer wood-bat league that, generally speaking, features the country’s best college prospects. Regarding Expected wRC+, What That Could Possibly Be One assumes that Expected wRC+ could be any number of things. In this particular case, however, it’s an attempt to represent in one number — a number a lot like wRC+, that is — something close to the “true talent” production of a player. Regarding Expected wRC+, How the Author Calculated It To calculate Expected wRC+, I found the home-run, walk, and strikeout rates for all the batters in the very prestigious Cape Cod League. After that, I attempted to find “expected” versions of those three rates by weighting each of them against league average until they reached their sample threshold for reliability. For example, Phil Ervin of the Harwich Mariners has a home-run rate of 7.3% in 150 plate appearances — but, per work by Russell Carleton, home-run rate becomes reliable only after 300 plate appearances. So, to find Ervin’s “expected” home-run rate, I weighted his 150 plate appearances’ worth of 7.3% with 150 plate appearances of league-average (2.2%) home-run rate. The result is Ervin’s 4.8% expected home-run rate. After finding the expected versions of the aforementioned rate stats, I calculated what is essentially a FIP for offense with them, multiplying home-run rate by 12, walk rate by three, and strikeout rate by two. From there, I finished by adjusting the results such that 100 equaled league average. Regarding a Thing That’s Possible It’s entirely possible that the plate-appearance sample thresholds for reliability — like for home-run rate and walk rate and strikeout rate — are different for the Cape Cod League than they are for the majors. Regarding What the Author Has Done About That Thing As he’s done for many other problems in his life, the author has opted to ignore this potential issue concerning sample sizes and reliability with the Cape Cod League.

He finished third on the team, behind a pair of seniors, in home runs (10) and led the team in stolen bases (16-for-21). Regarding Ervin, Baseball America’s Peter Wardell wrote last month: While it’s his offensive outburst that has garnered the attention of scouts thus far, Ervin’s performance in center field has been notable as well. He is an above-average runner with good instincts and a strong, accurate arm. He’s displayed adequate route running and good range, giving him the potential for five average to above-average tools.

Today’s MLB.TV Free Game San Francisco at St. Louis | 20:15 ET The Cardinals continue — according to NERD, at least, our infallible watchability metric — continue to be the league’s Most Interesting Team. They remain atop the leaderboard for Team wRC+ (113) and, according to WAR, have lost about six more games than they should’ve (while the first-place Reds have won about six more games than WAR would suggest makes sense). Of note: with a 162 wRC+, Matt Holliday is in the midst of the best offensive season of his career. Readers’ Preferred Broadcast: San Francisco Radio.
