first_imgST. LOUIS — Matt Adams could barely contain his enthusiasm — and he didn’t really try, either. He thrust both arms in the air while still in the batter’s box and added a couple of big hops to his home run trot as he approached first base.A stunned Clayton Kershaw, bent over at the waist with his hands on his knees, watched from the mound as the long drive off Big City’s bat propelled St. Louis to a fourth straight NL Championship Series.“Some people are calling it the Big City Leap,” Adams said. “I was just super-excited, I didn’t know what I was doing … I knew I was jumping for joy.”The Cardinals tagged Kershaw in the seventh inning for the second straight time, riding Adams’ go-ahead, three-run homer to a 3-2 victory over the Los Angeles Dodgers on Oct. 7th for a 3-1 win in the best-of-five Division Series.“I don’t think I touched the ground the whole way around the bases,” Adams said. “Definitely the highlight of my career. … I will never, ever forget this.” Neither will Kershaw.The Cardinals sent the Dodgers home for the second postseason in a row with a win over Kershaw. Last year it was in Game 6 of the NLCS.“The season ended and I was a big part of the reason why,” Kershaw said. “I can’t really put it into words, Just bad deja vu all over again.”The NLCS starts Oct. 11 in St. Louis, with the Cardinals hosting San Francisco in a rematch of 2012 won by the Giants.Trevor Rosenthal allowed two runners in the ninth before getting Carl Crawford on a grounder for a game-ending forceout for his third save of the series. At AT&T Park in San Francisco, fans cheered when the rival Dodgers were eliminated.“It was awesome, everything we did throughout that game,” starter Shelby Miller said. “It was a heck of a game and a lot of fun, I know that.”An overwhelming favorite to win his third NL Cy Young Award in four years, Kershaw’s October resume is a wreck.Kershaw dropped to 1-5 with a 5.12 ERA in 11 postseason games, including three relief appearances early in his career. He has lost four straight starts to St. Louis over the past two postseasons.“I’ve had success against them, too,” Kershaw said. “It just seems like one inning gets me every time. And obviously that’s not success.”While the steady Cardinals advanced to their ninth NLCS in 15 years, the defeat was a huge disappointment for the NL West champion Dodgers, who finished the regular season with a $256 million payroll that was $40 million higher than any other team.Los Angeles remains without a pennant since winning the 1988 World Series. “It’s awful,” catcher A.J. Ellis said. “It’s devastating. It just kind of rehashes those old memories.”Manager Don Mattingly wasn’t about to second-guess leaving Kershaw in the game, especially with a bullpen that’s foundered. He wanted the lefty to get three more outs.“It goes back to the same question: Is there anybody better, even on short rest, and even where he was at that point?” Mattingly said.Kershaw started on three days’ rest for the second time in his postseason career. He was dominant into the seventh, as he was in Game 1, but again started the inning with three straight hits.The third hit came when Adams, the burly bopper know as Big City, drove a curveball on Kershaw’s 102nd pitch into the right-center bullpen to put St. Louis up 3-2.“I had a pretty good idea that it was gone,” Adams said. The red-clad crowd roared and twirled white towels as Kershaw made a slow slog back to the Dodgers’ dugout.Kershaw allowed one homer to left-handed batters while going 21-3 with a 1.77 ERA in the regular season. He gave up two to the Cardinals, with Matt Carpenter connecting in the opener. The left-handed ace is 0-3 with a 9.72 ERA in his last three postseason appearances.Reliever Marco Gonzales earned his second victory of the series, after getting treated for a nosebleed. The rookie lefty got Adrian Gonzalez on a groundout to end the seventh and strand two runners.Pat Neshek worked a perfect eighth for the second straight game and Rosenthal pitched the ninth for a second straight day, receiving two visits to the mound from catcher Yadier Molina and one from the pitching coach after a shaky start to the inning.Kershaw had yielded only one hit through six innings and struck out nine, including three in a row in the sixth.But Matt Holliday opened the seventh with a sharp single up the middle off second baseman Dee Gordon’s glove, and Jhonny Peralta lined another single before Adams homered off a left-hander for the first time since July 7.The Cardinals had an NL-low 105 homers this season and left-hander batters had only eight homers against lefty pitching. But lefties hit five off Dodgers southpaws in four playoff games.Miller matched Kershaw into the sixth, when the Dodgers started the inning with two hits. They scored a run on Matt Kemp’s double-play grounder and added another on Juan Uribe’s RBI single against Seth Maness.But Los Angeles wasted a chance to add on when Andre Ethier, playing in place of Yasiel Puig, was picked off third by Molina — a call overturned by video review.Miller went 5 2-3 innings in his first postseason start.(R.B.

first_imgItaly coach Mancini delighted to have booked place at Euro 2020by Carlos Volcano13 days agoSend to a friendShare the loveItaly coach Roberto Mancini is delighted to have booked their place at Euro 2020.Mancini praised Italy for showing “patience” to beat Greece 2-0.The Azzurri have won all seven games in Group J and qualified for Euro 2020 with three matches to spare, something the Nazionale have never previously achieved.Jorginho converted a penalty and Federico Bernardeschi’s shot was deflected to secure the victory.Mancini said, “The lads did really well. First of all, I want to thank the fans at the Olimpico for coming out and supporting us, even if the first half when we were a bit tense, perhaps nervous at being back in Rome.“We wanted to dedicate the win to the kids at the children’s hospital,” the Coach told Rai Sport, referring to this week’s team visit.Greece put up a brick wall for an hour, but were eventually broken down by a penalty.“We’ll meet teams who sit back and defend. We were too frenetic in the first half, but should’ve patiently moved the ball around to open up spaces.

UPDATE (Feb. 25, 4:58 p.m.): Since publication of this post, the Last Man organizers have acknowledged that their database did not include one contestant who was still viable in the competition. She has since been eliminated, but the numbers in this post would be slightly different if the database had been correct at the time of publication. Eighty-five percent of participants have already been felled by what competitors call “The Knowledge,”2Not to be confused with “The Knowledge.” according to the Last Man website. Sixteen percent of all players had, despite their best efforts, learned who won the Super Bowl by midnight on the night of the game (Feb. 7).3I wasn’t a declared player, but I made it only to 9:17 a.m. the day after the game, by which point 27 percent of players had learned the result, too. By the end of the next day, more than half of the competitors had lost their blissful ignorance. The more time that passes, the safer the players are; only about a quarter of competitors who made it through the first post-Super Bowl week perished in the second. Now, as you can see in the chart above, the survivor curve is more like a plateau.But that’s no reason for the survivors to let down their guard. They could still be taken out by the kind of thing that has felled other competitors — phone calls, cupcakes, baby photos, the usual. And it’s not always just the Last Manners who suffer when they lose: One competitor learned the Super Bowl winner via “email from treacherous husband I thought I could trust.” And that husband may find that the guilt of being the spoiler weighs on him for longer than The Knowledge haunts his spouse. It’s been more than two weeks since the Super Bowl, and there are still at least 29 people1As of Sunday, when the data was last updated. who don’t know who won. Those 29 are the recorded survivors of the Last Man challenge, a war-of-attrition, just-for-glory competition to be the last person in the U.S. (or at least in the challenge’s database) unaware of who won Super Bowl 50. (For all of you who still don’t know who won, this post is a safe space.) read more

first_img Time in a bottle: Scientists watch evolution unfold Citation: Slower evolving bacteria win in the end (2011, March 18) retrieved 18 August 2019 from https://phys.org/news/2011-03-slower-evolving-bacteria.html Professor Richard Lenski of Michigan State University in East Lansing and colleagues aimed to work out if some changes in DNA affect the evolutionary potential, or “evolvability,” of organisms.In the study, the researchers investigated four genetically distinct clones of Escherichia coli clones, and sampled them periodically to look for the presence of five specific beneficial mutations. They discovered that after 500 generations all lineages had acquired beneficial mutations but two had significantly more than the others, which should suggest they were more likely to survive in the long-term than the other line of bacteria. What they found instead was that after 1,500 generations the other two lineages had gone on to dominate.One of the co-authors of the paper, published in the journal Science, Dr Tim Cooper of the University of Houston, Texas, said the bacterial “race” could be compared to the fable of the hare and the tortoise, saying that the hare would win a 100 meter race, but the tortoise might win a marathon. In the “hare” bacteria at least four beneficial mutations were present at the 500th generation, but despite this after another 883 generations they were growing over two percent slower than the other lineages, and by the 1,500th generation, they were extinct in the flasks.To try to find out why, they used frozen samples of the 500th generation of bacteria and ran the evolution experiment again a number of times. In almost, but not all, of these experiments the “tortoise” clones went on to win.They discovered that one of the genes in which beneficial mutations were found at the 500 generation mark was topA, a gene involved in winding DNA into a twisted band, which makes it easier for genes to be turned on and off. The mutations were slightly different in the slow and fast evolving bacteria, with the mutation in the “tortoise” bacteria affecting the next link down in the protein’s amino acid chain.After the 883 generations the “tortoise” topA mutation had interacted with a mutation in another gene called spoT, which increased its fitness. The topA mutation in the other lineages did not interact so favorably with later mutations and the spoT mutation was rendered useless, and made the “hares” less fit for long-term domination.The bacteria used in these experiments are part of a larger evolution study that has been running since 1988, or over 50,000 generations, which makes it the longest-running evolution experiment in the world. The experiment began with a dozen strains of E.coli, bred from a single ancestor. Every 500 generations (75 days), samples of the mixed-strains are frozen and stored and the mean fitness is compared to that of the ancestor.
