The Baseline forecast is also significant in that it attempts to remove luck from a forecast line. For example, a player who hit .310, but with a poor batting eye and unimpressive speed indicators, is probably not really a .310 hitter. Its more likely that hes a .290 hitter who had a few balls bounce his way, and the Baseline attempts to correct for this.
\nSimilarly, a pitcher with an unusually low EqHR9 rate, but a high flyball rate, is likely to have achieved the low EqHR9 partly as a result of luck.

Guest writer Alex Belth caught last night's Padres-Mets game, and details Mike Piazza's second game at Shea with the Friars.
It was an uncommonly pleasant night in New York, absolutely ideal for a game in mid-May or June, never mind August. The air was clean, with little to no humidity. A steady breeze swept through the open ballpark for the duration of the evening. There were more Piazza jerseys in the crowd than any other current Met, and the Padres' catcher, rounder in the face since he left New York, received ovations whenever he stepped onto the field. A crowd just shy of 50,000 came to their feet when Piazza led off the second inning. Pedro Martinez dispatched him on four pitches, catching him looking at a beautiful curve ball for strike three--and Piazza was showered with cheers as he returned to the dugout.
But the fun was just starting. Piazza threw the fans for a loop in the bottom of the inning when Endy Chavez reached first base. Two middle-aged men with New York accents straight out of Damon Runyon sat in field box seats down the third base line. One said, "This guy is running here. They can steal all day off Piazza." Sure enough, Chavez took off for second, but to the surprise of nearly every paying customer in the joint, Piazza's throw nailed him by plenty.
Allen Barra has written for numerous publications since the late-1970s, including The Village Voice, The Wall Street Journal, and currently The New York Times. In 2002, Barra authored Clearing the Bases: The Greatest Baseball Debates of the Last Century, which took a refreshing look at some of baseball's most argued topics. Recently, BP correspondent Alex Belth caught up with Barra to discuss his early days as a writer, the influence of Bill James on his work, and Major League Baseball's marketing department.
Baseball Prospectus: So what team did you root for as a kid?
Roger Angell, The New Yorker's celebrated baseball writer, has a new compilation out titled Game Time, which contains many new pieces along with some previously published ones as well. BP correspondent Alex Belth caught up with Angell last weekend and talked about growing up a New York Giants baseball fan, the present-day Yankees, plus other topics New York baseball-focused and otherwise.
Baseball Prospectus: How did you get your start as a baseball fan, and as a writer?
After the 1975 Andy Messersmith arbitration ruling in which the reserve
clause was deemed to cover one, and only one, season, Major League Baseball
and the Players Association eventually agreed on a structure for free
agency, but the antitrust exemption remained. The Supreme Court has made it
clear that it would not overturn the exemption, insisting that only Congress
could do so.
Baseball is the only major sport that has an exemption from antitrust law.
Whenever Major League Baseball is involved in a major controversy, Congress
starts talking about revoking the exemption. This talk reached a fever pitch
during the 1994-95 players' strike, but nothing happened. After that labor
war, MLB and the Players Association agreed to lobby Congress for a limited
repeal of the exemption where labor matters are concerned.
