With Pedro Strop sidelined by a hamstring injury Bryce Harper Jersey , Chicago Cubs manager Joe Maddon gave the ball to Jorge De La Rosa for the ninth inning.And it worked.The 37-year-old De La Rosa got three outs for his first career save, helping the Cubs top the Cincinnati Reds 3-2 on Friday night.Ian Happ hit a three-run homer in the seventh inning as NL Central-leading Chicago stayed 1 1/2 games ahead of second-place Milwaukee, which posted a 7-4 victory over Pittsburgh. Ben Zobrist had three hits, and Dillon Maples (1-0) earned his first career win.De La Rosa surrendered a one-out double to Curt Casali and walked Billy Hamilton with two down before Scott Schebler flied out to center. It was the first save opportunity for Chicago since Strop strained his left hamstring trying to beat out a double-play grounder during Thursday’s 4-3 victory at Washington, shelving the key reliever for the rest of the regular season.Strop had been subbing for closer Brandon Morrow, who is on the disabled list with a right arm injury.After Cole Hamels allowed two runs over 6 2/3 innings, Maples got the final out of the seventh, Jaime Garcia tossed a perfect eighth and De La Rosa closed it out in his 426th major league appearance.Maddon called it an “unlikely bullpen.”“The walk to Hamilton made it interesting, but (De La Rosa) had great composure,” he said. “First big league save Stephen Strasburg Jersey , wow. Good for him.”Happ’s homer was just his second in 22 games. The 24-year-old switch hitter is batting .186 over the span.“It’s been a while since I’ve had one of those,” Happ said. “To get a hit in that situation coming off what we’ve had to do the last couple of weeks, to give us a chance to win a ballgame, it was great.”Cincinnati had won four of six, including two of three against the contending Los Angeles Dodgers. The last-place Reds wasted a terrific start by Matt Harvey, who struck out six in six scoreless innings.“It was just about getting ahead,” Harvey said. “The big thing was being able to mix different pitches for a strike and really throw it whenever I wanted to.“That was the first time in a long time that all four pitches were kind of doing exactly what I wanted to.”Cincinnati jumped in front on consecutive homers by Jose Peraza and Joey Votto in the fourth, but Chicago rallied after Harvey was replaced by David Hernandez (5-1).Victor Caratini led off the seventh with a single and David Bote reached on an error on third baseman Eugenio Suarez. After pinch-hitter Tommy La Stella hit into a forceout, Happ drove a 1-0 pitch into the bleachers in left-center.Hamels struck out seven to increase his career total to 2,396 http://www.nationalsfanproshop.com/authentic-gio-gonzalez-jersey , matching Sandy Koufax for 48th on the all-time list. He is 4-0 in nine starts since he was acquired in a trade with Texas.CLOSER CONUNDRUMStrop had 11 saves in 13 opportunities since Morrow went on the DL in July. He is 6-1 with a 2.26 ERA over 59 2/3 innings in 60 appearances.Unless the Cubs can make a trade, Maddon said he envisions using a closer-by-committee approach, including veterans Steve Cishek, Justin Wilson and Jesse Chavez.TRAINER’S ROOMReds: RHP Lucas Sims is sidelined with a strain on his right side. “He’s got little something going on with his lat that he’s not available to pitch right now,” manager Jim Riggleman said.Cubs: Morrow (right biceps inflammation) is scheduled to throw a simulated game on Saturday. … Maddon said OF Jason Heyward (right hamstring tightness) might return next week.UP NEXTReds LHP Cody Reed (0-2, 5.08 ERA) faces Cubs ace Jon Lester (15-6, 3.57 ERA) on Saturday. Lester lost his last start on Monday to Milwaukee, exiting after 5 2/3 innings with lower back tightness. ATLANTA (AP) — Atlanta Braves rookie Ronald Acuna Jr. has struck again.The 20-year-old Acuna has become the youngest player in major league history to homer in five straight games, doing it Tuesday night when he hit his third leadoff shot in a row. Then he added another in the seventh inning, a three-run shot for his 19th of the season.A day after hitting leadoff homers in both games of a doubleheader against Miami Anthony Rendon Jersey , Acuna connected. He opened the bottom of the first inning against the Marlins by homering on the first pitch for the second straight day.

He tied the Atlanta record of five straight with a homer set by Brian McCann in 2006.The only other player younger than 21 to homer in four straight games was Miguel Cabrera for the Marlins in 2004.Acuna is hitting .352 with 11 homers since moving to the top of the batting over, a stretch of 24 games beginning right after the All-Star break. The outfielder went 5 for 8 with two homers, five RBIs, five runs, two walks, a double and a stolen base in Atlanta’s doubleheader sweep of the Marlins.After Acuna circled the bases, Charlie Culberson homered on the second pitch from Miami’s Trevor Richards.
