CHICAGO -- Paul Goldschmidt cleared his head after being overpowered by Jeff Samardzija in his first three at-bats. Goldschmidt hit a tiebreaking grand slam in the eighth inning, leading the Arizona Diamondbacks to a 12-4 victory over the Chicago Cubs on Saturday night. Arizona starter Ian Kennedy (3-3) allowed four runs on three hits in seven innings and retired 20 of the final 21 batters he faced to help end Chicagos five-game winning streak. Gerardo Parra led the game off with a home run and Jason Kubel hit a bases-clearing double in the seventh inning for the Diamondbacks, who won for just the second time in 12 games at Wrigley Field. Nate Schierholtz hit a solo shot and an RBI double, but the Chicago bullpen couldnt hold a 3-1 lead for Samardzija, who was relieved after throwing 115 pitches. With the scored tied at 4 in the eighth inning, Parra hit what looked to be a go-ahead RBI double off Cubs reliever Carlos Marmol (2-3), but the ball got stuck in the ivy in the centre field wall, resulting in a ground-rule double. Willie Bloomquist, who was running on the pitch and wouldve easily scored from first, was sent back to third base. After a walk to load the bases, Goldschmidt hit a long shot off Marmols slider to centre field for his first career grand slam, giving the Diamondbacks an 8-4 lead. Goldschmidt struck out in his first three at-bats against Samardzija. "You can have three bad ABs, I dont even know if that qualifies as bad ABs. Samardzijas stuff was really good, but you get a chance to win the game in the eighth or ninth you cant live in the past," Goldschmidt said. "Its a game of failure. Its what the game is all about." Diamondbacks manager Kirk Gibson knows the feeling of rebounding after a few bad at-bats. "You are there, you are striking out, the fans are yelling at you, youre disappointed that youre letting the team down, but it is a great feeling when you come through. It happened to me many times," Gibson said. The Diamondbacks scored a season-high 12 runs and had a season-high 17 hits. Trailing 3-1 in the seventh inning, Goldschmidt worked a walk against Samardzija to put runners on first and second and end Samardzijas outing. After retiring the first batter he faced for the second out, Cubs reliever James Russell walked Martin Prado, and Kubel followed with a double to clear the bases and give Arizona a 4-3 lead. "One thing we did good against him we got his pitch count up. Then we got into their bullpen we got some big hits and won the game," Gibson said. After retiring 17 straight batters, Kennedy was tagged by Schierholtz for a home run leading off the bottom of the seventh. It was Schierholtzs seventh of season. "It was probably only the second time I shook off Miggy (Miguel Montero) all game. He called a great game," said Kennedy. "It was one of those things, Gosh darn it, I should have stayed with it." Samardzija showed flashes of his dominant performance against the White Sox on Monday, but was pitching in and out of trouble most of the night. He allowed three runs and seven hits, while striking out 11 and walking three. In his previous outing against the White Sox, he pitched a two-hitter while striking out eight. The Cubs bullpen gave an up nine runs and 10 hits with four walks in 2 2-3 innings. "The bottom line is, you walk eight guys, youre not going to win too many games, no matter what, when you walk eight guys. It basically came down to the walks. Obviously they got a couple big hits to bust the game open. But the walks were the difference in the game," Cubs manager Dale Sveum said. After a 2-hour, 21-minute rain delay, Parra led off the game with a home run to right. It was the fourth time in his career he led off a game with a home run and it was his fifth of the season. "Theyre a fastball-hitting team, theyre really aggressive. I knew they were on it, especially after Parras first at-bat, so I started making better pitches. Used my slider to get ahead in the count and kind of got back on track there. Splitter was good. Just avoid those walks in the seventh," Samardzija said. With no outs in the first inning, the Cubs loaded the bases. David DeJesus scored on Alfonso Sorianos sacrifice fly then Schierholtz hit an RBI double down the right field line. Anthony Rizzo scored on Welington Castillos ground out to give the Cubs a 3-1 lead. Sveum was ejected by home plate umpire Joe West in the second inning after arguing a close call at first base. It was his second ejection of the season. Kennedy was back on the mound after missing his last start because he cut his right index finger while washing a knife.

NEW YORK -- The NFL will be hiring a full-time chief medical officer to work with team medical staffs, the players union and league committees.In a letter sent to the 32 team presidents and obtained by The Associated Press on Wednesday, Commissioner Roger Goodell said the chief medical officer also would work with the broader independent scientific and medical communities.The new hire will replace Dr. Elliot Pellman, who is retiring after 30 years in the league, and will have expanded duties.Pellman mostly played an administrative role that included communication with NFL clubs regarding health and safety protocols. Pellman was not a member of any league medical committee. But much of the early criticism of the NFL regarding its handling of concussions was directed at Pellman, who once famously downplayed links between head trauma and football.Pellman is a rheumatologist with little expertise in head and brain trauma research, but he was involved in the formulation of the NFLs concussion policies.Goodell also told the teams that the NFL must demonstrate strong leadership on health and safety and that our players and fans need to trust in us.In recognition of this priority (on player health and safety) and the increasing complexity of our work, we intend to hire a highly credentialed physician to serve as Chief Medical Officer and work in the league office on a full-time basis, Goodell wrote.A search will begin this week and will be conducted by a panel of health and medical experrts led by Dr.dddddddddddd Betsy Nabel, the leagues chief health and medical adviser.Others on the search panel will include Dr. Rob Heyer, president of the NFL Physicians Society and team internist for the Carolina Panthers; Ronnie Barnes, senior vice president and head trainer for the New York Giants; Dr. Robert Cantu of Boston University;, and Peter Foss, of G.E. Healthcare. The panel will work closely with the leagues Jeff Miller.Nabel was hired in February 2015, but she also serves as president of Brigham and Womens Health Care.While the NFL has been heavily criticized in its handling of head trauma over the decades -- it reached a settlement that will pay about $1 billion over 65 years to more than 20,000 retired players -- Goodell has tried to emphasize the progress made in several health and safety areas. Those include 42 rules changes to protect players; millions of dollars spent in medical research; and more mandatory protective equipment.During games, team sidelines have at least 27 medical professionals, including some independent observers such as neurologists. There are strict guidelines and protocols for concussions and head injuries.Clearly, though, Goodell felt the need for someone new at the top of the leagues medical hierarchy who will have a broader role while working solely for the NFL.---www.pro32.ap.org and www.twitter.com/AP-NFL ' ' '
