What a day (and a night) for home runs

Some of them came late. A lot of them traveled far.

Wednesday’s major league baseball action was notable for home runs -- the volume hit, the distance they traveled and the effect they had on games.

Lots of LONG long balls

There were 10 home runs calculated to have traveled 430 feet or longer Wednesday, the second-most on one day since ESPN began tracking homers in 2009. The only other day with more is July 27, 2009, when 12 were hit.

There were more homers 430 feet or longer than there were home runs of less than 400 feet (nine).

Wednesday’s longest home run came off the bat of Edwin Encarnacion, whose fourth-inning shot at Rogers Centre was calculated at 471 feet, tied for the seventh-longest home run of the season. It was his second-longest home run since ESPN began tracking homers in 2009, trailing a 488-footer he hit on Sept. 1, 2012.

At Coors Field, Carlos Gonzalez hit a home run calculated at 455 feet. One inning later, Franklin GutiĆ©rrez hit a 445-foot home run, his longest -- by one foot -- since the start of the 2009 season. Gutierrez’s 444-foot home came Sept. 24, 2009, at Rogers Centre.

The locations of the long long balls hit by Encarnacion, Gonzalez and Gutierrez aren’t coincidental. Coors Field has been the site of 45 home runs of 430 feet or longer this season. Rogers Centre is second in yielding home runs of that distance with 30.

When Welington Castillo hit a 432-foot home run in the eighth inning of the Diamondbacks’ game against the Nationals, it was the 10th home run of 430-plus feet Wednesday. The previous high this season was eight, on May 6.

The average distance of the 430-foot home runs is 445 feet, and their total distance was 4,446 feet (more than eight-tenths of a mile).

In all, 29 home runs were hit Wednesday, with an average distance of 413 feet and a total distance of 11,977 feet. That's the longest average distance since ESPN began tracking homers in 2009 (on a day with a minimum of 20 home runs).

Homers here and there

Andrew McCutchen hit a home run calculated at 448 feet, his longest home run of the season and tied for the second-longest of his career.

David Ortiz hit a home run calculated at 441 feet, the second-longest at Yankee Stadium this season. The longest: 453 feet by Alex Rodriguez on July 22.

Miguel Sano hit the longest home run by a Twins player this season with a 447-foot shot at Rogers Centre.

Evan Longoria hit the second-longest home run at U.S. Cellular Field this year, a 439-foot shot that trails only teammate Grady Sizemore’s 443-foot homer Monday night.

When it counts the most

Chris Davis became the sixth player in Orioles history to hit a grand slam in extra innings, giving them a 7-3 win over the A’s in the Orioles’ last at-bat. Before Wednesday, Matt Wieters was the most recent Orioles player to hit a grand slam after the ninth inning, having done so in 2012 and 2013. Before that, the Orioles hadn’t done it since Harold Baines accomplished the feat in 1999.

There was another last-inning home run in the Rockies-Mariners game, in which Michael McKenry hit his first career walkoff homer in a 7-5 win for Colorado in the 11th inning. McKenry’s home run was hit a mere 425 feet, the shortest of the three in the game.
