:BRAVE NEW WORLDRookie phenom Ronald Acuna Jr. will try to get the first-place Atlanta Braves off to another fast start when they visit Arizona in a matchup of NL playoff contenders. Acuna hit his eighth leadoff homer Wednesday Mariano Rivera Jersey , setting a club single-season record, but the Braves blew a late six-run lead in an excruciating 9-8 loss to Boston at home. Brandon Phillips’ two-run homer with two outs in the ninth inning of his long-awaited season debut capped the biggest comeback by the Red Sox this year. On the heels of a three-game sweep, Anibal Sanchez (6-5, 2.98 ERA) looks to get Atlanta back on track when he faces Zack Greinke (13-9, 2.97) and the Diamondbacks in the opener of a four-game series. Acuna has 24 homers, including 17 since the All-Star break.GETTING CLOSERWith their magic number down to eight Babe Ruth Jersey , the Cleveland Indians attempt to move closer to a third consecutive AL Central title when they play at Toronto. Lefty reliever Andrew Miller (sore shoulder) is expected to throw a bullpen before the game. He’s been on the disabled list since Aug. 29.CLOSING TIMENo telling who the Chicago Cubs will use as their closer when the NL Central leaders open a series at Washington. Brandon Morrow held the job through the All-Star break, but hasn’t pitched since then because of a biceps injury. He hasn’t thrown off a mound during his recovery. Pedro Strop has gotten the ball in the ninth inning lately, but has never been a full-time closer. Steve Cishek and Justin Wilson also could perhaps fill in. Manager Joe Maddon says even if Morrow heals, it’s hard to say how he’d be used.CHECK HIMPhillies third baseman Maikel Franco has returned to Philadelphia to have his sore right wrist examined by a specialist. He didn’t play in the three-game series at Miami this week. Franco is expected to rejoin the team later this week. The Phillies, who have lost four of five while trying to catch Atlanta in the NL East, play this weekend vs. the Mets in New York. Adam Glanzman/Getty ImagesBoston Red Sox star J.D. Martinez stood behind a 2013 Instagram post that attributed a fake quote to Adolf Hitler.The post included a picture of Hitler that read: "To conquer a nation http://www.yankeesfanproshop.com/authentic-giancarlo-stanton-jersey , First disarm it's citizens."TheNew York Daily News' Kate Feldman provided a screenshot of the post:Kate Feldman kateefeldmanI just...what...

I stand by the Constitution and I stand by the Second Amendment and it's something that I take pride in. It's something that I'll back up.At the time I posted that, the Second Amendment at the time was definitely a hot topic.The point of it wasn't to offend anybody."Chad Amaral of Boston 25 News shared Martinez's full comments from Tuesday:Chad Amaral Chad_AmaralJD Martinez on controversial Instagram post quot;Im here to play baseball guys, Im not a politician....

Still, Red Sox team president Sam Kennedy told theBoston Herald'sSteve Buckleythe team had addressed the situation with Martinez.Kennedy said the Red Sox "work with our players regularly to reinforce that their social media interactions can be interpreted in ways that are unintended."Controversy about his past social media habits aside, Martinez is having an incredibly successful debut season in Boston.He's batting.338 with 38 home runs, 110 RBI and a .656 slugging percentage, and his 5.4 WAR is tied for seventh-best among MLB position players Mickey Mantle Jersey , perFanGraphs.The Red Sox need that production to continue as they look to remain on top in the American League East and avoid the wild-card game in the postseason.
