After having their EFL Cup title dreams dashed in midweek, both Arsenal and West Ham United seek to regroup Saturday in a London derby at Olympic Stadium.Both teams fielded weakened sides in their quarterfinal matches and both unsurprisingly came up second-best. The Gunners (8-4-1) had their 19-match unbeaten streak in all competitions come to an end with a 2-0 home loss to Southampton -- their first defeat since opening with a 4-3 setback to Liverpool on Aug. 14 -- while the Hammers second match in four days at Old Trafford resulted in a 4-1 defeat to Manchester United that extended their overall winless streak to five (0-2-3).Arsenal manager Arsene Wenger overturned nearly his entire starting XI for the EFL Cup match, and their youthful inexperience showed against a Saints side that also made substantial changes since it is juggling Europa League commitments around domestic action. Wenger, who has never won the EFL Cup in his 20 years on the Arsenal touchline, was frustrated with his teams lack of cohesion and cutting edge -- especially in a sluggish first half when they conceded both goals.Its not only a disappointing night because were out, but its a disappointing night because the performance was disappointing, he said. I question our urgency level, our focus from the start on. It was not good enough and we paid for that.The run we want to keep in the Premier League, but I am very disappointed because there are questions on important things. You know, when you turn up in the first 45 minutes we played.The Gunners have won just once in their last five matches overall (1-3-1), raising concerns over whether this will wind up being like most recent years in which Arsenal -- currently fourth in the table but only three points adrift of frontrunners Chelsea -- are good enough to secure Champions League qualification and the riches that help perpetuate their success while failing to mount a serious charge at the Premier League title.Carl Jenkinson endured another torrid time at fullback, a position where he is third-choice due to injuries to Hector Bellerin and Mathieu Debuchy. He will likely get his second league start in this match since Bellerin is expected to be sidelined at least two more weeks and Debuchy has a hamstring ailment that could sideline him another month.Wenger has injury concerns about forward Olivier Giroud and influential holding midfielder Santi Carzola, as both were held out of Wednesdays match. Mohamed Elneny, who was subbed off at intermission due to illness, is expected to be available.As north London deals with the disappointment of a rare Gunners defeat, the gloom and misery continues on the east side of the city as the Hammers continue to be unable to put together consistent performances on a match-to-match basis.A lack of focus early in both halves cost West Ham dearly as they fell behind two minutes into the contest and then allowed a back-breaking go-ahead goal to Anthony Martial three minutes after intermission in Wednesdays setback.After the slow start, we recovered and looked good but you cant do the same, manager Slaven Bilic said. And we did. They (Manchester United) totally deserved it then after that. You just cant have that kind of start in a game like this.West Ham (3-3-7) are languishing perilously above the relegation spots in 16th, one point clear of the drop. They also have fresh injury concerns Michail Antonio and Aaron Cresswell were both subbed off during the match and are questionable for this match. One player Bilic must replace is forward Diafra Sakho, who has been ruled out the next six weeks with a thigh injury suffered after scoring early in Sundays draw versus Manchester United.That puts even more pressure on Dimitri Payet to begin following up on his breakout 2015-16 season in which he had 13 goals and 14 assists in all competitions. The France international has just two goals and five assists in this campaign.We have a tough game on Saturday and we have a couple of players who came off injured, but we wanted to preserve players for then and Dimitri Payet also, Bilic said. Its unbelievable that when we get a couple of injuries like the ones we got today (after them all season) and its very tough for us now.The Hammers ended a 15-match winless spell against Arsenal in all competitions in emphatic style last season, winning 2-0 at the Emirates on goals by Cheikou Koyate and Mauro Zarate on either side of halftime.In the return encounter at Upton Park, Andy Carroll ran riot with his aerial supremacy and had a hat trick in an eight-minute span around intermission, single-handedly rescuing West Ham from a two-goal deficit to provide a 3-2 lead. Laurent Koscielny, however, spared Arsenals blushes with an equaliser on 70 minutes to salvage a point for the Gunners.Arsenal were unbeaten in their last nine (7-2-0) at Boleyn Ground and 12-7-2 there in all competitions during the Premier League era. West Ham have yet to turn Olympic Park into an intimidating venue, taking just eight points from six matches (2-2-2) while being outscored 9-6. Pat ODonnell Jersey . The judges scored it 48-47, 48-47, 49-46 for Jones (19-1). It was the champions closest call. Despite the loss, it was a remarkable show by the confident Swedish challenger, who had the best of the early rounds and then hung on in the fourth and fifth. Paddy Driscoll Jersey .

WASHINGTON -- With Stephen Strasburg not expected to pitch in the National League Division Series and Joe Ross not yet fully stretched out after a two-month layoff, the Washington Nationals are counting on Gio Gonzalez to come through in the playoffs.But in his final start of the regular season, Gonzalez struggled with his command and quickly built a high-pitch count in a 3-0 loss to the Arizona Diamondbacks in a rain-shortened game Wednesday.The start of the game was delayed 33 minutes by rain and was later called with one out in the top of the sixth inning after a second delay of 70 minutes.It wasnt that good, but we didnt score any runs either, manager Dusty Baker said of Gonzalezs outing. He had a lot of pitches in a short period of time. He was 0-2 on a couple guys, then went to 3-2. Most of the night he pitched behind.The NL East-champion Nationals have lost two of three to the last-place Diamondbacks and seven of their last 11 games overall.Shelby Miller threw five shutout innings for Arizona and Jean Segura had three hits to reach 200 for the season.Miller (3-12) capped an otherwise forgetful season with one of his best outings of the year, allowing five hits with one walk and striking out five. In his previous start, Sept.23 in Baltimore, Miller threw six scoreless innings in a no decision.I wish maybe I would have done this earlier on but the way I just finished these past couple games is huge and just something to build off going into 2017, Miller said after earning his first win since June 20.I just feel good where Im at. I know where Im at mechanically and stuff so I can go forward into 2017 with more confidence and knowing that Im feeling good.Segura joined Luis Gonzalez as the only players in Diamondbacks history with 200 hits in a season.Just a great feeling, Segura said. Its amazing especially since Ive been bouncing around the couple last years. Im impressed, Im not going to lie to you guys, Im impressed with the way Ive been swinging the bat this season. I dont think nobody expect Id have the season Im having right now.Gonzalez (11-11), Washingtons projected No. 3 starter in the NLDS against the Los Angeles Dodgers, tossed 3 2/3 innings, allowing eight hits and three runs with four walks and four strikeouts.ddddddddddddBaker noted that while the Diamondbacks had a first-ball hitting approach against Max Scherzer on Tuesday, they had a different game plan against the inconsistent Gonzalez Wednesday.Tonight, they were taking, getting deep in the count, Baker said. They ran his pitch count up. They didnt swing at very many balls and it looked like they were trying to wait on his fastball.The lefty threw 100 pitches, but just 56 for strikes.I had some 0-2s that ended up getting soft hits through the hole so its just a tough situation, Gonzalez said. Just cant do nothing about it. Learn to pitch ahead of the count.In his final five starts of the season, Gonzalez allowed 19 earned runs in 23 innings (7.43 ERA) with a 1.78 WHIP.You start the postseason with a zero ERA, he said. Its a new series. New way to look at it.PITCHING FOR A FALLEN FRIEND:Before taking the mound for his final start of the season, Gonzalez said a prayer and pointed to the sky as a tribute to his friend Jose Fernandez, who died Sunday in a boating accident. Gonzalez, a Cuban-American, will leave the Nationals on Thursday to attend Fernandezs funeral in South Florida.TRAINERS ROOMDiamondbacks: RHP Zack Greinke did not accompany the Diamondbacks on their final road trip of the season due to right shoulder soreness. Manager Chip Hale said Wednesday that Greinke is not throwing and he is not expected to pitch again this season.Nationals: Outfielder Bryce Harper was not in the Nationals starting lineup for a third straight game because of an injured left thumb. Harper is considered day to day, but manager Dusty Baker said that he did not want to risk the NL MVP in a wet outfield.UP NEXTNationals RHP Joe Ross (7-5, 3.48 ERA) is scheduled to make his third start since returning from the disabled list Sept.18 against Diamondbacks LHP Robby Ray (8-14, 4.77).
