The tater trots for May 8 were dominated by Josh Hamilton's four home runs versus the Orioles in Baltimore.
The night was dominated by one ultra-rare occurrence that had only happened 15 times before: Cesar Izturis's home run for the Brewers, the 16th home run of his career. I suppose a few people were also talking about the four home runs Josh Hamilton put up against the Baltimore Orioles last night, too.
Remembering the late Don Mincher with a look back at the second part of his BP interview from last year.
While looking toward the future with our comprehensive slate of current content, we'd also like to recognize our rich past by drawing upon our extensive (and mostly free) online archive of work dating back to 1997. In an effort to highlight the best of what's gone before, we'll be bringing you a weekly blast from BP's past, introducing or re-introducing you to some of the most informative and entertaining authors who have passed through our virtual halls. If you have fond recollections of a BP piece that you'd like to nominate for re-exposure to a wider audience, send us your suggestion.
First baseman Don Mincher died on Sunday at age 73. In his memory, we're re-running David Laurila's two-part interview with him, which originally ran as a two-part "Prospectus Q&A" column on January and 11th and 12th, 2011.
Roundtable discussion of the pressing questions facing the NL East teams as we approach the start of the season
1) After a disappointing sophomore campaign, what can we expect of Jason Heyward going forward?
MJ: Jason Heyward had an injury-riddled sophomore season in Atlanta, but there is a lot to like about his chances at a rebound campaign in 2012. His offensive line was deflated by a .260 BABIP, but his peripherals were once again stellar. His 11.6 percent walk rate represented a regression from 2010 but cannot be considered poor, and his .162 ISO likewise dropped from the previous year but did not experience a precipitous fall.

You might not know it from watching the World Series, but it often makes sense for a manager to pinch hit for his starter before the late innings.
Believe it or not, most of our writers didn't enter the world sporting an @baseballprospectus.com address; with a few exceptions, they started out somewhere else. In an effort to up your reading pleasure while tipping our caps to some of the most illuminating work being done elsewhere on the internet, we'll be yielding the stage once a week to the best and brightest baseball writers, researchers and thinkers from outside of the BP umbrella. If you'd like to nominate a guest contributor (including yourself), please drop us a line.
Mitchel Lichtman, or MGL, has been doing sabermetric research and writing for over 20 years. He is one of the authors of The Book: Playing the Percentages in Baseball, and co-hosts The Book blog, www.insidethebook.com. He consulted for the St. Louis Cardinals from 2004 to 2006, as well as other major-league teams. He holds a B.A. from Cornell University and a J.D. from the University of Nevada Boyd School of Law. Most of the time these days you can find him on the golf course.
Recently, there has been a lot of digital ink spilled about ERA estimators—statistics that take a variety of inputs and come up with a pitcher’s expected ERA given those inputs. Swing a cat around a room, and you’ll find yourself with a dozen of the things, as well as a very agitated cat. Among those is SIERA, which has lately migrated from here to Fangraphs.com in a new form, one more complex but not necessarily more accurate. We have offered SIERA for roughly 18 months, but have had a difficult time convincing anyone, be they our readers, other practitioners of sabermetrics, or our own authors, that SIERA was a significant improvement on other ERA estimators.
The logical question was whether or not we were failing to do the job of explaining why SIERA was more useful than other stats, or if we were simply being stubborn in continuing to offer it instead of simpler, more widely adopted stats. The answer depends on knowing what the purpose of an ERA estimator is. When evaluating a pitcher’s performance, there are three questions we can ask that can be addressed by statistics: How well he has pitched, how he accomplished what he’s done, and how he will do in the future. The first can be answered by Fair RA (FRA), the third by rest-of-season PECOTA. The second can be addressed by an ERA estimator likeSIERA, but not necessarily SIERA itself, which boasts greater complexity than more established ERA estimators such as FIP but can only claim incremental gains in accuracy.
Which players off to a powerful start at the plate can expect to retain that production going forward?
In a season where offense is tough to come by, fantasy owners are looking in every nook and cranny and under every rock looking for power. Power hitters can effect three of the scoring categories in one swing of the bat, hence the premium price for it on draft day. The quick and dirty way to find power sleepers has traditionally been to look at players’ Isolated Power score, and find those batters who had a score of .200 or better. However, that is just one way to find your surprise power, because an attractive ISO this time of year may not be sustainable based on other peripherals. Here are a few players that are going to pop up on your ISO radar as you go searching for help.
