The New York Mets looked motivated to end their five-game losing streak after a four-run first inning against the Philadelphia Phillies on Thursday. However, it all went downhill for Carlos Mendoza's team after the opening frame of the contest.The Mets conceded six unanswered to lose 6-4, their sixth consecutive defeat, leading to a sweep against their division rivals. After the loss, Mets manager Carlos Mendoza was asked if he was "worried" about the team's wild card spot, he said:"Teams are right behind us," Mendoza said. "The way you look at it is, we’re still in control of the situation, we’re still in control of the ultimate goal. We just have to go out and do it."Mendoza's answer has frustrated Mets fans who vented their anger on social media."Stay not worried bro it’s fucken over."DeeDubb @DeeDubb24LINKStay not worried bro it’s fucken over.“Still in control?' you haven’t been in control for the past 2 months, many of us saw this coming a mile away."Stacy NYC @Hustlediva1LINK“Still in control” you haven’t been in control for the past 2 months, many of us saw this coming a mile away"Not worried? DUDE! We lost the whole series, pitching besides the young ones has been horrible, hitting doesn’t even exist. Is like like the Mets play 5 good games and then 15 bad. Sorry but you should be worry."Javier @BearNBeets0080LINKNot worried? DUDE! We lost the whole series, pitching besides the young ones has been horrible, hitting doesn’t even exist.

"Frustrating, but nothing we can do about it now. We have to get back at it tomorrow, go back home and win some baseball games."The Mets have gone 5-10 in their last 15 games and could end up losing their playoff spot if their slide continues. However, they are back in Queens for their next nine games, which could spark a turnaround for the Mets as they hold a 45-27 record at Citi Field this season.
