ST. LOUIS (AP) Marcell Ozuna had always dreamed of hitting a game-ending homer http://www.bravesfanproshop.com/authentic-julio-teheran-jersey , and finally did it.Ozuna got the his first of his career in the 10th inning Monday night, and the St. Louis Cardinals snapped Colorado’s four-game win streak with a 5-4 victory over the Rockies.”I’ve been working on it so many times,” Ozuna said. ”I was in that situation before and I couldn’t get it. Today was the time.”Ozuna connected against Jake McGee (1-4), sending a one-out drive deep to center for his 13th homer of the season. The slugger also extended his homer streak to three straight games.”Missed my spot over the middle of the plate. He was looking fastball too,” McGee said. ”Got to be a little more careful especially with a home run hitter like that.”Dakota Hudson (1-0) got three outs for his first career win.St. Louis has won eight games on game-ending hits this season and has won three of its last four contests.Colorado took a 4-0 lead when Nolan Arenado hit his fifth career grand slam in the fifth inning off Daniel Poncedeleon, who replaced Carlos Martinez when the right-hander departed with a mild shoulder strain with two outs.Arenado went deep for the third time in four games. The drive to center gave him 79 RBIs, one behind Cincinnati’s Eugenio Suarez for the National League lead.Martinez was activated from the disabled list prior to the game. He missed his previous start with a right oblique strain.”He just said my shoulder is sore but I can still go,” Cardinals interim manager Mike Shildt said. ”The velocity was down a little bit. We just looked at it and went out and the rest was what it was.”Colorado left-hander Tyler Anderson allowed four runs in six-plus innings. He was replaced by Scott Oberg after he walked the first three batters in the seventh.”That ended up costing us the game so it’s obviously pretty bad Greg Maddux Jersey ,” Anderson said. ”I just felt like I didn’t know where the ball was going there.”Dexter Fowler then struck out, but Harrison Bader walked and Matt Carpenter hit a tying two-run single with two out.Charlie Blackmon singled off Martinez in the fifth to extend his hitting streak to 12 games, matching his season high.Gerardo Parra initially scored on a pitch from Poncedeleon to Anderson that sailed to the backstop in the sixth inning. The call was overturned after the Cardinals challenged the ruling on the field that Parra evaded Poncedeleon’s tag.Jedd Gyorko homered in the fifth inning for St. Louis. It was Gyorko’s first since July 5 and No. 8 on the season.”That’s a huge answer right there,” Shildt said. ”Come back, it’s 4-1 and get them on their heels a little bit.”TRAINER’S ROOMRockies: RHP Chad Bettis (right middle finger blister) threw a pregame side session.

Every fifth day Scherzer (16-6, 2.28) gives the Nationals a chance to win.Article continues below ...“Watching him, he’s the best. He really is. Watching him prepare on a daily basis has been incredible,” Nationals manager Dave Martinez said. “He competes every day. His work ethic is far beyond what I’ve ever seen. The mental part, the physical part of it.“For four days R.A. Dickey Jersey , he puts his body through a lot and his mind through a lot to get ready for his opponents on the fifth day.”Scherzer, seeking his third straight NL Cy Young Award, enters Saturday atop the National League in wins (16), strikeouts (260), innings pitched (193.2) and opponent’s batting average (.179), and third in ERA (2.28).He’s allowed as many as four earned runs in only two starts this season, the last on July 7.

After two hours and 55 minutes, with the rain having stopped, the game was postponed by Major League Baseball.Cubs manager Joe Maddon said earlier in the day he was hoping to get the game in.“It’s supposed to rain here for three days,” Maddon said. “We can plow through. We’ve done that already this year so many times. We’d rather plow through this than a doubleheader and a make-up game. We’re going through 23 in a row, so we need to play this.”Left-hander Jaime Garcia (3-6, 5.93) will pitch the first game for the Cubs. His contract was purchased from Triple-A Iowa on Tuesday. Garcia is 5-3 with a 2.91 ERA in nine career starts against the Nationals.Chicago right-hander Cole Hamels (4-0 Kurt Suzuki Jersey , 1.00 since joining the Cubs) was originally scheduled to oppose Scherzer in Saturday’s game, but now with the doubleheader, he’ll pitch the nightcap. The Cubs acquired Hamels from the Rangers at the July trade deadline and have gone 6-1 in his starts.Hamels has fanned 43 and walked 12 in 45 innings for Chicago and has let to allow a home run. He was named the National League Pitcher of the Month for August. Last time out, he gave up two runs in six innings against the Brewers.The former Philadelphia Phillie is 16-9 with a 2.63 ERA in 36 career starts against the Nationals.Washington did not immediately name its Game 2 starter.The Nationals on Friday activated left-hander Sean Doolittle from the 10-day disabled list. The Washington closer missed 54 games with a stress reaction in his left foot.Doolittle is 3-2 with a 1.45 ERA. His 22 saves (in 23 chances) are tied for eighth best in the National League.“It’s tough mentally for different reasons to have to be on the sidelines and watch kind of the way the second half of the season unfolded for us and not being able to contribute, not being out there with the guys was really tough,” Doolittle said.
