Each of the New York Mets, Cincinnati Reds and Oakland Athletics came from five runs down to win in Monday's MLB action.
The New York Mets hit a franchise-record eight homers in their 16-7 rout of the Philadelphia Phillies, including two to Wilmer Flores.
Flores, David Wright, Juan Lagares, Travis d'Arnaud, Michael Cuddyer, Daniel Murphy and Yoenis Cespedes all went deep for the Mets, after Ryan Howard clobbered a three-run homer to put the Phillies 3-0 up in the first inning.
In fact, the Phillies and Mets went homer-for-homer in the first three innings, as the Phillies built a 7-2 lead.
But Flores' line drive to left field at the top of the fourth was the first of five straight homers for the Mets, and the first of 14 unanswered runs.
Wright's homer in the second inning was significant - the 32-year-old rising to the occasion at his first at-bat since returning from a career-threatening spine injury.
Not one Phillies pitcher was spared - starter Adam Morgan conceding four homers - but it was Hector Neris who earned the loss after he allowed four earned runs in 1.1 innings work, including two homers.
It was the Mets' fourth straight win, taking them 5.5 games clear top of the East division in the National League (NL)
NL Central leaders the St Louis Cardinals increased their buffer to 3.5 games, with a 5-3 victory over the Arizona Diamondbacks.

AL Central leaders the Kansas City Royals were 8-3 winners at home to the Baltimore Orioles.
Rusney Castillo batted in all of the Boston Red Sox's runs, as they claimed a 5-4 win at the Chicago White Sox.
JA Happ struck out six in six innings pitched, leading the Pittsburgh Pirates past the Miami Marlins 5-2, while the Cincinnati Reds arrested a five-run deficit with a 10-run sixth to down the Detroit Tigers 12-5.
The Oakland Athletics were the third team to come from five runs down and win, matching the Mets' and Reds' heroics to saunter to an 11-5 result over the Seattle Mariners.
The Atlanta Braves beat the Colorado Rockies 5-3 and the Chicago Cubs walked off against the Cleveland Indians 2-1.
Travis d'Arnaud, New York Mets: Finishing a triple shy of the cycle, d'Arnaud went three-for-five with three RBIs.

FACT OF THE DAY
With 11 strikeouts against the Cubs, Indians starter Corey Kluber recorded his 19th double-digit strikeout game since 2014. Only White Sox ace Chris Sale (20) has more in the past two seasons.
Good: Pirates outfielder Gregory Polanco went four-for-five with two doubles, a stolen base and an RBI.
Bad: For the fourth time in eight second-half starts, Orioles pitcher Ubaldo Jimenez gave up six or more runs. This time it was to the Royals, who scored six runs off Jimenez in the sixth inning alone.
Alfredo Simon is high on confidence as he leads out the Tigers at home to the Angels, the Rays welcome the Twins in a key battle for an AL wildcard, and the Cubs will have Jake Arrieta on the mound when they take on the Giants in San Francisco.
