Since starting the season 9-19, a disastrous opening act that caused the organization to switch managers, the Phillies have completely turned things around. Don Mattingly's team completed a Rivalry Weekend sweep of the Pirates on Sunday for their fourth straight win. Philadelphia is now 15-4 since employing the nuclear option, which has been enough to elevate them past .500 and into second place in the National League East. What was once a massive hole does not seem as daunting as the Braves' division lead has been shaved down to eight games and a wild card spot is only 3 1/2 games out of reach. It's a remarkable turn around on a dime and new life has been breathed into the franchise even quicker than the biggest optimist would have hoped.The immediate turnaround mirrors what happened four years ago as a mid-season managerial change ushered in a 14-2 run and an eventual trip to the World Series. This upcoming stretch of play, beginning with the Reds coming into town on Monday, will reveal just how hot the Phillies are—and if they are for real.Boston also pulled the rip cord on its skipper after a 10-17 start, yet the Red Sox haven't been able to capture the same lightning in a bottle, going 9-10 since the move and getting no closer to what they need to do.In the American League East, the Yankees continue to give up ground to the Rays. New York has lost seven of its past 10 contests to fall a full three games behind blistering Tampa. The surprising White Sox are nipping at the Guardians' heels in the AL Central (1 1/2 games back), the AL West is a logjam of mediocrity (with the .500 Athletics atop the leaderboard) and the NL West is a two-horse race between Los Angeles and San Diego. A Cubs cool-off has allowed the Brewers and Cardinals to get within a 1 1/2.The Brewers and Cubs face off beginning Monday night in a pivotal series at Wrigley and the Tigers have a much-needed chance to breathe some life into their miserable May by taking on the Guardians. For a late-night treat, the Dodgers and Padres will square off for the division lead.MLB scoresRays 6, Marlins 3Orioles 7, Nationals 3Phillies 6, Pirates 0Braves 8, Red Sox 1Guardians 10, Reds 3Blue Jays 4, Tigers 1Mets 7, Yankees 6Rangers 8, Astros 0White Sox 9, Cubs 8Twins 5, Brewers 4Royals 2, Cardinals 0Diamondbacks 8, Rockies 6Giants 10, Athletics 1Dodgers 10, Angels 1Padres 8, Mariners 3MLB standingsAmerican League EastTeamRecordGames BehindRays30-15--Yankees28-193.0Blue Jays21-259.5Orioles21-2610.0Red Sox19-2711.5American League CentralTeam RecordGames BehindGuardians26-22--White Sox24-221.0Twins21-264.5Tigers20-275.5Royals 20-275.5American League WestTeam Record Games BehindAthletics23-23--Rangers22-241.0Mariners22-262.0Astros19-295.0Angels16-317.5National League EastTeam RecordGames BehindBraves32-15--Phillies24-238.0Nationals23-249.0Marlins21-2611.0Mets20-2611.5National League CentralTeam RecordGames BehindCubs29-18--Brewers26-181.5Cardinals27-191.5Pirates24-235.0Reds24-235.0National League WestTeam RecordGames BehindDodgers29-18--Padres28-180.5Diamondbacks22-236.0Giants20-279.0Rockies18-2911.0MLB scheduleAll times ETGuardians vs. Tigers, 6:40 p.m. Orioles vs. Rays, 6:40 p.m. Reds vs. Phillies, 6:40 p.m. Braves vs. Marlins, 6:40 p.m. Mets vs. Nationals, 6:45 p.m. Blue Jays vs. Yankees, 7:05 p.m. Red Sox vs. Royals, 7:40 p.m. Astros vs. Twins, 7:40 p.m. Brewers vs. Cubs, 7:40 p.m. Rangers vs. Rockies, 8:40 p.m. Athletics vs. Angels, 9:38 p.m. Dodgers vs. Padres, 9:40 p.m. Giants vs. Diamondbacks, 9:40 p.m.White Sox vs. Mariners, 9:40 p.m. More MLB from Sports IllustratedAdd us as a preferred source on GoogleFollow
