Morning Mound Visit: sabermetrics news - 3/27/19

FanGraphs | Devan Fink: Chase Anderson may have been a decent rotation arm for the Brewers in their pennant run, but now he makes the jump to the bullpen. In that jump he’ll have to change his repertoire, as his fastball has declined in velocity and his sinker has been home run prone.

Baseball Prospectus | Rob Mains ($): One of the main issues with the current CBA is how it deals with pitchers, whose role has completely changed in the time it was even negotiated. Pitchers have less service time than hitters overall, and fewer of them even get enough service time to even reach arbitration. This means that the cast of bullpen arms are a wider pool of lower-paid, lower-leveraged employees who can be swapped and traded at will for incredibly low prices.

Tangotiger Blog | Tom Tango: Tango delves deeply into the fundamentals of pitch framing, and I’m highlighting just Part 1 but there are subsequent editions on his site. He breaks it down by pitches in a “shadow zone,” where pitches could be balls or strikes, and then use WOWY (with or without you) to adjust for pitcher and park to get your run values. I’m paraphrasing here but it’s definitely useful now that pitch framing is part of FanGraphs’ WAR.
