"I think it's tremendous," said Astros manager Bo Porter, whose club recognized veterans from every conflict since World War II on the field. "When you think about our country and all the things we've been through, to be able to have a day where the entire league honors the veterans and what it is our country stands for, it's great for baseball and great for our country."
Veteran Pat Duncan, 90, threw out the ceremonial first pitch in Houston after being recognized for surviving the Dec. 7, 1941, attack on Pearl Harbor while serving in the Navy. He received eight commendations and medals over his career.
The occasion was particularly meaningful to Houston outfielder Robbie Grossman, whose father, Rob, spent 11 years in the Navy and was an aviator in the first Gulf War. Rob Grossman was a Seahawk pilot who flew helicopters off the back of frigates, cruisers and destroyers.
"It's a tribute to the people who served this country and fought for our freedoms and everything we have and take for granted," Robbie Grossman said. "It means a lot to me."

Martin Dempsey, Chairman of the Joint Chiefs of Staff, greeted the ballpark crowd with a scoreboard message from Bagram Airfield in Afghanistan.

A graduate of West Point and a MIT doctorate, Aldrin was also a fighter pilot in the Korean War, with 66 combat missions.
"Memorial Day is very important to me, because I'm a military person," Aldrin said. "I had some very close friends who were POWs. I think veterans should be very proud."

In the visitors' clubhouse at AT&T Park in San Francisco, Oakland's Josh Donaldson donned camouflage cargo shorts prior to the game before slipping into his special-edition uniform for the ballgame. Reliever Jerry Blevins was one of the many who donned his camouflage A's cap as soon as he saw it hanging in his locker.
"It's a national day," Blevins said. "This is about letting people gather today and as a society, as a people, taking the time to appreciate it all. As much as baseball is America's pastime, what they do is much more important."
Senior Airman Ben Akers proposed to his girlfriend, Kirsten Opperman, before the first pitch in Kansas City, where the first 20,000 fans received miniature American flags.

Prior to the Interleague game between the Cubs and White Sox in Chicago, Challenger, the bald eagle, flew across the pitcher's mound during the national anthem, and five members of the armed forces threw a ceremonial first pitch.
"It's one of the bigger holidays we have in the country," said Cubs manager Dale Sveum, who has three tattoos to honor his father, George, who was a Marine. "To take a day and remember what people sacrificed for the things we get to do out here. It is a really special day. Besides Christmas, I think it's the biggest holiday."
