LOS ANGELES -- The semifinal playoff series between the Los Angeles Sparks and Chicago Sky could hinge on the recovery of Elena Delle Donnes thumb.Delle Donne had surgery recently, and coach Pokey Chatman said she wont play in Game 1 of the best-of-five series that begins Wednesday at Long Beach State and is doubtful for Game 2.Chicago guard Allie Quigley is impressed with how the Sky have played without the star forward.I just think we knew when she went down that we were all going to have to step up, Quigley said. Everyone was ready. Were not going to be like the team where, Oh, theyre not that good without Elena. Everyone took it personal and stepped up big.The second-seeded Sparks, who had a double bye and havent played in 12 days, are planning for all scenarios, with or without Delle Donne. Chicago is planning to play without her.The Sparks, who had the second-best record in the league at 26-8, have shortened practices and structured them more like games in preparation for the playoffs.I also think theres an element of two things happening, Sparks coach Brian Agler said. I think we sat around for 5? weeks and everyone told us how good we are, and I think we softened up. Thats No. 1. No. 2, now its playoff time. Its easier to get peoples attention. I cant tell you the outcome of the games, but I think well be more engaged and focused.Delle Donne has captured the attention of the WNBA and its fans. And in her absence, her teammates are showing they can become a more guard-oriented team and be successful at it.Credit the players for stepping up individually and collectively, Chatman said. Unfortunately, in the past weve had to do that. Elena has suffered with some injuries and the back injury. Theres not this collective sigh or panic on the players part.Dont misunderstand me, its an arduous task ... but also, its the beauty of sports that someone goes down and someone steps up. Some veteran players like Cappie Pondexter, Courtney Vandersloot and Tamera Young, theyve stepped up and changed the way we played in terms of our pace.The fourth-seeded Sky have played well without Delle Donne, going 4-2 with her out of the lineup.Chicago must play the Sparks with all of their All-Stars, like Candace Parker and WNBA MVP Nneka Ogwumike. Ogwumike led the team in scoring with 19.7 points per game.The Sparks have won all three meetings against Chicago this season, all by double digits.While the Sparks were waiting through byes, they scrimmaged and on Tuesday, visited with the homeless in nearby Venice and passed out blankets and shoes.They were back scrimmaging on Tuesday.Theyre playing great basketball, and theyve been without [Delle Donne], Parker said. Weve got to prepare for them. They have so many different weapons.Delle Donnes absence, and her regular-season scoring average of 21.5 points per game, is glaring for Chicago, which beat Atlanta to advance.We prepare like shes never coming back because everything else would be Merry Christmas to us, Chatman said. You have to because you dont want to put undue pressure on her to come back too soon if shes not ready. Nike Shoes Black Friday Sale .

Nike Shoes Black Friday Discount . PETERSBURG, Fla. PITTSBURGH -- Jordy Mercer knows the routine. He figured it was time he experienced it for himself. The Pittsburgh Pirates second baseman singled up the middle off Gonzalez Germen with two outs in the 11th inning to send teammate Andrew McCutchen sprinting home with the winning run in a 3-2 victory over the New York Mets on Friday night. Mercer celebrated the first walkoff hit of his career and the sixth of Pittsburghs stunning season by flipping his bat in the air and then running for safety. "You make them chase you down because you know youre going to get punished afterward, punched and stuff," Mercer said. "Its all worth it in the end, though." McCutchen led off the 11th with a walk, stole second and then easily beat the throw home from centre fielder Juan Lagares to end the Mets four-game winning streak. The Pirates stayed one game behind St. Louis in the tight NL Central race. Vin Mazzaro (5-2) retired all three batters he faced to earn the victory. Starling Marte had two of Pittsburghs six hits, and Pedro Alvarez added his 24th home run. Mets All-Star David Wright had two hits and extended his hitting streak to 12 games. He had an RBI single but also flied out with two runners on to end the New York 10th. Kirk Nieuwenhuis hit his third homer of the season for New York. Germen (0-1) got only two outs in his first inning in the majors and took the loss. He struck out Alvarez and Gaby Sanchez with McCutchen on second before Mercers grounder slipped by shortstop Omar Quintanilla and into the outfield. "He made some great pitches, too," Mets manager Terry Collins said of Germen. "The 3-1 pitch to Gaby Sanchez was about as (gutsy) of a pitch that youll ever see." The game carried a little more heat than usual between one team in the midst of a pennant race and another rebuilding. Wright, the starting NL All-Star third baseman and Home Run Derby captain, added Alvarez to the NLs derby roster on Thursday after Colorados Carlos Gonzalez pulled out because of a hand injury. Still, Wrights perceived initial snub of Alvarez wasnt forgotten by Pirates fans. He was booed lustily before each at bat, even though he and Alvarez -- who will make his All-Star debut -- exchanged a handshake and a brief chat before the national anthem. "Theyre knowledgeable fans, they know whats going on and its cool that theyre upset and passionate about it," Wright said. "It made for a nice atmosphere." Alvarez wasted little time celebrating. One batter after Jose Tabata reached on an infield single in the bottom of the first, Alvarez hit the first pitch he saw from Jeremy Hefner into the New York bullpen in centre field.dddddddddddd. He trotted past Wright without looking up as the seventh sellout crowd of the season roared. Alvarez, a New York native, dismissed any sense of payback with his blast. He considers Wright a friend and would rather focus on his breakout season. "I just try to hit the pitch where its pitched, and just trying to make good contact and really not worry about trying to put too much on the ball," he said. "You cant really control the home runs. I try my best to make good contact wherever the ball is." Hefner settled down and retired 14 straight after Alvarezs homer, needing just 78 pitches to get through seven innings. He allowed three hits and struck out three without issuing a walk. "Last year and even at the beginning of this year I would have folded or given up more runs or whatever the case may be," Hefner said. "Ive been able to bounce back, turn the page and give quality outings after giving up some runs early." It marked the eighth straight start in which Hefner gave up two earned runs or fewer, the longest streak by a Mets pitcher since Johan Santana did it over 13 starts between 2008 and 2009. Pitt
