In a world of concrete stats like RBI’s, Wins, ERA etc - there is an overwhelming amount of underlying statistics, with one true purpose. To accurately measure the contribution of the player and remove elements from the game such as luck or contributions from other players. With that said I wanted to highlight 3 “new” stats and/or changes to existing ones. fWARI’ll start with fWAR, as I would say WAR has been one of the most commonly adopted statistics even outside of the sabermetrics community. WAR is intended to be as close as possible to an all-encompassing stat to measure a players value. Frustratingly, there are numerous versions of the stat as Baseball Reference / Fangraphs etc disagree on some elements and how to value them. Regardless, fWAR (Fangraphs) is the one I utilize most, and they had a significant change in their measurement as of 3/20/19 - with the inclusion of Catcher framing - for both Pitchers and Catchers.I won’t go into the full explanation as Fangraphs has a whole article explaining their thought process and calculations. It also compares their pitch framing statistics to the other major sites to see if it is in line with their calculations. Lastly, they did an article on the impact to WAR here.Baseball ProspectusDRC+Baseball Prospectus released a new statistic this year called DRC - Deserved Runs Created, with the plus basically indicating that higher is better. They wrote a whole article on the new statistic which you can read here , but for a high level analysis, So why use DRC+ over OPS+ or WRC+? According to Baseball Prospectus Trevor Rosenthal Jersey , it i simply far more accurate, descriptive, and predictive statistic. (Full Analysis of comparison is listed on their page). How is it done? Instead of utilizing what actually occurred, Baseball Prospectus is utilizing what the expected results would be to calculate DRC. DRC+ uses the same 100 as league average rating as you’ve grown accustomed to with OPS+/WRC+, to compare the percent better or worse than league average. Truthfully, DRC to me seems like a more refined version of WRC+, and should replace WRC+ in my usage, though I’m admittedly timid to make this change without more research on my part. StatcastxWOBAAlthough still viewed as somewhat experimental, xWOBA is extremely interesting to me. If you’re familiar with WOBA (Weighted On Base Average) - that looks to measure a player’s overall offensive contributions on a per plate appearance basis utilizing linear weighting. WOBA is scaled to be like OBP. WOBA was found to be a better tool than OPS, Runs Created, etc. It feels somewhat off to use a metric that looks like OBP to measure pitchers, but it does provide a usable statistic. xWOBA is the Expected Weighted On Base Average, which you can read a full article about here. With the release of statcast data, there is a revolution on-going in the statistics in baseball. Having exit velocity, launch angle, and even Sprint Speed allows us to build out much more of expected results taking out the variance for excellent/poor defense and other aspects that would generally fall into “luck” http://www.stlouiscardinalsteamshop.com/authentic-marcell-ozuna-jersey , allowing for a statistic that is far more predictive in the future and descriptive of the actual player’s contributions. Tell me what you feel about the new statistics. LOS ANGELES (AP) — While one homer after another rocketed into the stands at Chavez Ravine, the Los Angeles Dodgers‘ dugout celebrations became increasingly incredulous.Five homers in the first six innings? Followed by three more in swift succession in the seventh? Even the Dodgers’ power-packed lineup was impressed by itself.“We were all wondering if it was a record,” Enrique Hernandez said with a grin.After the Dodgers finally finished hitting eight home runs in a 12-5 victory over the Arizona Diamondbacks on Thursday, they all agreed they had never experienced an opening day quite so powerful.Neither had any team in major league history, actually.Hernandez and Joc Pederson each homered twice as Los Angeles set the big league record for homers on opening day and tied the franchise mark for any game.The Dodgers’ pursuit of a third straight National League pennant and seventh consecutive NL West title got off to a thrilling start, with no trace of a hangover from that World Series-ending loss to Boston in their previous game on this field last October.Hernandez, Austin Barnes and Corey Seager all homered in the fourth inning to chase Arizona ace Zack Greinke. Max Muncy, Cody Bellinger and Hernandez then connected in a four-batter stretch of the seventh, abruptly obliterating the opening day record of six homers set by the Mets in 1988 and matched by the White Sox in 2018.“This is a fun offense,” Muncy said. “A couple of guys go out and get a homer, and it makes you want to get one of your own.”Los Angeles also equaled the franchise mark for a game set against Milwaukee on May 23, 2002, when Shawn Green hit four of the Dodgers’ eight.“Hitting is contagious,” Bellinger said. “You see guys hit, and you want to get into the party.”The Dodgers finished second in the majors last season with 235 homers, and they were even more potent in their first regular-season game under new hitting coach Robert Van Scoyoc. All eight dingers were hit by returning players to the Dodgers Carlos Martinez Jersey , who have only two new position players on their opening day roster.“Everyone kind of knocked us last year for scoring too many runs off homers,” Muncy said. “But if you’re going to do it, you might as well do it like that.”Adam Jones and Christian Walker went deep for the Diamondbacks, but their pitching staff’s eight homers allowed also set a team record.The Dodgers provided ample support for Hyun-Jin Ryu, who yielded four hits and struck out eight over six stellar innings as Los Angeles’ first opening day starter not named Clayton Kershaw since 2010. Kershaw’s franchise-record streak of eight consecutive opening day starts ended due to left shoulder inflammation.Meanwhile, Greinke’s latest return to Dodger Stadium was a debacle.The $206.5 million right-hander allowed four homers for the fifth time in his career, but only the second time this decade. The Dodgers also hit four against their former star on Sept. 5, 2016, in Chavez Ravine, where Greinke has allowed 14 homers in 34 innings since his big-money move to Arizona.“Yeah, it was bad,” Greinke said. “Not really much to build off, because all that stuff was bad, so that’s probably the most disappointing thing.”Arizona reliever Matt Koch allowed the Dodgers’ other four homers over a seven-batter stretch in the sixth and seventh. The embarrassing loss added to a rough week for the Diamondbacks, who lost probable cleanup hitter Steven Souza Jr. to a season-ending knee injury Monday.“You band together, and you get off the ropes Lance Lynn Jersey , stagger back into the middle of the ring and keep punching,” manager Torey Lovullo said. “And I know this team will do that.”JOC STARTPederson delivered as the Dodgers’ leadoff hitter. After doubling and scoring in the first inning, he hit one of Greinke’s curveballs 420 feet to straightaway center in the second. He added a two-run shot off Koch in the sixth before the Dodgers reached historic homer territory in the seventh.SEAGER’S RETURNTwo outs after Hernandez and Barnes hit back-to-back homers, Seager chased Greinke with his first homer since April 28. Seager was back in the Dodgers’ lineup for the first time since missing nearly all of last season due to Tommy John surgery.POLLOCK’S STARTA.J. Pollock played center field and batted fifth in his Dodgers debut, going 0 for 3 with a walk. Pollock, who spent the previous seven seasons with the Diamondbacks, and Justin Turner were the only Dodgers starting position players who didn’t homer.JONES’ DEBUTJones went 2 for 4 while batting leadoff for the Diamondbacks, who signed the 33-year-old outfielder 17 days ago. Jones spent the previous 11 seasons in Baltimore, making five AL All-Star teams.TRAINER’S ROOMDiamondbacks: Lovullo put Walker at first base on opening day instead of Jake Lamb, who was injured for part of spring. Paul Goldschmidt had been Arizona’s starting first baseman for the previous seven opening days.Dodgers: Kershaw formally went on the injured list before the game along with lefties Rich Hill and Tony Cingrani.UP NEXTRoss Stripling is back in the Dodgers’ rotation for now, and the versatile 2018 All-Star welcomes the chance to prove himself while Kershaw and Hill are out. He faces Arizona lefty Robbie Ray, who looked great during spring training with 32 strikeouts in 16 1/3 innings.
