PITTSBURGH -- Pittsburgh Pirates second baseman Neil Walker understands not everybody is going to be a fan of Major League Baseballs expanded replay system, which threatens to slow down a sport that already struggles to be played with any sort of urgency. Funny, there werent many critics to be found on Monday at PNC Park. Walker homered off Carlos Villanueva leading off the 10th inning, and the Pirates benefited from an overturned to call to beat the Chicago Cubs 1-0. The Pittsburgh native turned on a Villanueva changeup and sent it sailing over the Clemente Wall in right field for the first walk-off of his career and the first by the Pirates on opening day since Bob Bailey homered off San Franciscos Juan Marichal in a 1-0, 10-inning victory in 1965. "This one feels pretty special," Walker said. "This is a special day for this team, this organization. Weve come a long way." So has the game. After spending decades fighting the advances of technology, Major League Baseball has embraced the concept. Many calls can be challenged this season under an expanded system, and both teams wasted little time putting umpires to work. The Cubs made history by initiating the first review under the new guidelines. Chicago manager Rick Renteria challenged a double-play call in the top of the fifth following a demonstrative "safe" call by Jeff Samardzija following a poorly executed sacrifice bunt attempt. First base umpire Bob Davidsons decision was confirmed on replay. "It was a combination of Samardzjias reaction and what we were looking at," Renteria said. "Were still trying to figure out what clear and compelling evidence is. Its a work in progress." Chicagos luck with replay didnt get any better later. A safe call on a pickoff attempt by Bryan Morris (1-0) with one out in the top of the 10th was reversed after Pirates manager Clint Hurdle requested a replay, sending Chicagos Emilio Bonifacio back to the dugout after a delay of 2 1/2 minutes. "Most of the time on pickoffs, its got to be very noticeable for the umpire," Morris said. "Those bang-bang plays are always going to go to the runner. I guess thats why its good to have replay." The largest regular season crowd in PNC Parks 14-season history (39,833) roared its approval. The din only grew louder when Walkers drive to right field finished halfway up the seats. That capped a giddy day for a team freed from two decades of losing after a breakout 2013 in which it won 94 games and made the playoffs for the first time since 1992. Former Pittsburgh star Barry Bonds presented centerfielder Andrew McCutchen with the NL MVP award that McCutchen earned last year. Bonds received mixed reviews, though the vitriol that accompanied his late career visits to Pittsburgh while playing for San Francisco was noticeably absent. Bonifacio went 4 for 5 for Chicago, but the Cubs were 0 for 11 with runners in scoring position and wasted a fine start by Samardzija, who scattered five hits over seven innings. "I was happy with the way I kept the ball down in the strike zone," Samardzija said. "It helped to get the double plays because they made the overall outing look a little better than it really was." Travis Ishikawa had two of the six hits by Pittsburgh. Starter Francisco Liriano tied a team record shared by three other pitchers for most strikeouts on opening day by fanning 10 in six innings. While he struggled with his command -- needing 104 pitches to get 18 outs -- he was sharp when he needed to be and Pittsburghs bullpen did the rest.

Kiriasis and brakeman Franziska Fritz finished two runs in one minute 55.41 seconds -- a mere 0.01 seconds ahead of Meyers and Lolo Jones, who likely bolstered her Olympic hopes by helping give USA-1 a huge push in the second heat. Anja Schneiderheinze and Stephanie Schneider were third for Germany, 0.07 seconds back. Meyers has now finished no worse than second in all five races this season, though this one wasnt easy. She and Jones had a bit of trouble at the start of the first run, then tied for the fastest start in the field to begin their second trip down the track. "We like to keep everybody on the edge of their seats," Meyers said after extending her World Cup standings lead to 68 points over reigning Olympic champions Kaillie Humphries of Calgary and Heather Moyse of Summerside, P.E.I., who finished fifth. "We had a little slip-up in the beginning of the first run. I didnt run far enough and she followed me, so it caused us to drop some time, but we came back in the second one." Jenny Ciochetti of Edmonton and Chelsea Valois of Zenon Park, Sask., finished in 14th place, 1:36 behind the winning duo. Kiriasis victory came one day after she celebrated her 39th birthday. It was the first medal of the season for the German whos widely considered the best womens driver ever, and came in whats widely expected to be her final year in a sled. Kiriasis was emotioonal crossing the finish line, raising one of her index fingers skyward, then took a long swig of a celebratory beer while standing atop the medal stand.dddddddddddd. For the U.S., Jamie Greubel and Aja Evans led after the first run but finished fourth. Jazmine Fenlator and Lauryn Williams were ninth, despite solid start times of 5.62 and 5.59 seconds. Evans is expected to be a lock for one of the three push-athlete jobs on the U.S. womens team that will compete in the Sochi Olympics next month, while Jones and Williams -- both of whom have competed in multiple Olympics as track stars -- are in a group competing for the other two spots. Later Sunday, Germany swept a four-man race, dominating once again on home ice. Maximilian Arndt won his second gold medal in as many days, prevailing in 1:50.09 to extend his lead in the World Cup four-man standings. Francesco Friedrich drove to silver in 1:50.32 and Thomas Florschuetz took the bronze in 1:50.49. Olympic champion Steven Holcomb and his team of Steve Langton, Curtis Tomasevicz and Chris Fogt finished seventh for the U.S., wrapping up a tough, crash-filled week in Winterberg for the Americans. Also for the U.S., the team of Cory Butner, Adam Clark, Andreas Drbal and Chris Langton placed 13th, while pilot Nick Cunningham and push athletes Dallas Robinson, Johnny Quinn and Abe Morlu were 16th. The World Cup bobsled tour continues next weekend at St. Moritz, the next-to-last weekend of competition before the Americans will decide which athletes will be on the team for next months Sochi Olympics.
