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.

That assertion is getting harder and harder to make, especially given the way 23-year-old Danilo Gallinari has been playing this season. ANAHEIM, Calif. -- About two hours after Yoenis Cespedes made a defensive play for the ages, Collin Cowgill decided not to watch while the Oakland left fielder chased after his long drive in the 14th inning. Cespedes couldnt do a thing about this one as Cowgill delivered another resilient win for the Los Angeles Angels. Cowgill hit a two-out homer, and the Angels outlasted the Oakland Athletics 2-1 on Tuesday night for their fifth consecutive victory. The Angels bounced back after Cespedes kept it tied in the eighth with a throw that will be a fixture on highlight reels for years, cutting down Howie Kendrick at the plate with a 300-foot heave on the fly from deep down the left-field line. After five ensuing scoreless innings, Cowgill abruptly connected against Jeff Francis (0-1), driving a two-strike pitch just over Cespedes head into the bullpens beyond left field. "I was just hoping it had enough on it to get it over his head," said Cowgill, who had three hits. "That guy has made some incredible plays on us the last couple of times." Josh Hamilton drove in Mike Trout in the sixth for the Angels, who trimmed Oaklands lead in the AL West to 2 1/2 games. The Angels could have ended it earlier, but Albert Pujols and Kendrick both were thrown out at the plate -- although it was tough to blame Kendrick after Cespedes made his mind-boggling throw in the eighth. "Hes capable of doing just about anything on the baseball field, and thats just another example," said Jed Lowrie, who drove in Oaklands only run. The Cuban left fielder bobbled Trouts double and chased it down before his soaring throw went straight to catcher Derek Norris to nip Kendrick, who had already rounded third when Cespedes released it. "When that ball rolled to the corner, I thought Howie was going to score standing up," Angels manager Mike Scioscia said. "He threw a guided missile that was right on the money." Cory Rasmus (2-0) pitched two hitless innings for Los Angeles maligned bullpen, which yielded one run in eight excellent innings even without closer Ernesto Frieri, who had pitched in four straight games. Nick Punto doubled and scored on Lowries sacrifice fly in the eighth for the AL-leading As, who have lost four of six. "Hey, what can you ddo?" manager Bob Melvin said.dddddddddddd "They played as hard as they could, both teams did. After a while, everybody is trying to win it with one swing. Unfortunately, we werent at our best today offensively." Pitching and defence dominated the latest meeting of Californias division rivals. Neither starting pitcher allowed a runner into scoring position until the sixth. Hector Santiago struck out eight during six innings of three-hit ball in his first start in five weeks for the Angels. Drew Pomeranz pitched seven innings of four-hit ball for the As, allowing only an unearned run. The Angels got a terrific fill-in start from Santiago, recalled from Triple-A Salt Lake after Tyler Skaggs went on the disabled list. Santiago lost his spot in Los Angeles rotation May 7 after going 0-6, but the Angels off-season acquisition from the White Sox limited powerful Oakland to three singles and one walk. "I had clean mechanics and felt like everything was smooth," Santiago said. "Thats what I went down there to work on, and the results came out." Santiago faced no real trouble until the sixth, when he struck out Josh Donaldson to strand two runners. Pomeranz yielded just two singles before Trout drew a leadoff walk in the sixth. Pujols reached on a throwing error when Donaldson, who made three throwing errors from third base Monday, tried to start a double play. Hamiltons single scored Trout, but Pujols ran straight through third-base coach Gary DiSarcinas stop sign and was easily thrown out at the plate. Oakland tied it against reliever Mike Morin after Punto hit a leadoff double. After Cespedes kept it tied, the As put two more runners on in the ninth, but Joe Smith got John Jaso to ground out. NOTES: Angels rookie Cam Bedrosian pitched two extra innings of one-hit relief. He is the 22-year-old son of 1987 NL Cy Young Award winner Steve Bedrosian. ... Angels SS Erick Aybar swung and hit Norris in the back of the head with his follow-through in the fourth. Baltimores Manny Machado twice did the same thing to Norris last weekend, and the As were furious after Machado expressed no remorse when Norris had to leave the game. Aybar immediately checked on Norris, who was fine this time. ... Donaldsons three throwing errors Monday all went to first base. ' ' '
