In 1969, Buzz Aldrin and Neil Armstrong became the first men to walk on the moon.
It was also the last time a pair of Houston Astros players sent home run balls into orbit as grand slams in the same game.
Jimmy Wynn and Dennis Menke both hit slams to beat the New York Mets on July 30, 1969. The feat actually came in the same inning.
On Sunday, Chris Carter and Jon Singleton each hit grand slam's in Houstons's 14-5 win over the Minnesota Twins. Carter's blast came in the seventh inning to make the score 9-3 and Singleton added even more insurance with a ninth inning dinger.
Carter and Singleton weren't the only Astros swinging hot lumber as Dexter Fowler and George Springer each hit home runs, too. They were both solo shots. The 14-run output was the most for the Astros since early in the 2013 season.
Houston remains in last place in the American League West Division. The Astros are 28-36 and sit 11.5 games behind the first place Oakland Athletics. However, they are one of the hottest teams in baseball.
The Astros have won 11 of their last 15 games and are 17-10 since May 11. The offense has been leading the turnaround, much like it did against the Twins on Sunday and for the entire weekend series.
They took two of three from the struggling Twins. On Friday, the top half of the Houston order each collected at least one hit in a 5-4 victory. Matt Dominguez led the charge with three hits and a pair of RBIs.
Dexter Fowler went 2 for 2 in a loss on Saturday, bringing his batting average up to .276 which is second-best on the team.
Singleton has only been on the big league roster for six games. Sunday was the first multi-hit game of the 22-year-old's career. He also doubled in the fourth inning, his first in the majors.
Singleton went to the plate six times in the big win, however he also struck out three times. In fact, he's racked up 10 Ks already in just 25 at-bats. The first baseman has had four multi-strikeout games in his only two series playing with the Astros.
Plate discipline seems to be the only flaw in his game, though. Singleton had a batting average of around .280 with 77 home runs in a four-year stint in the minor leagues. He hit 14 homers this season alone with Triple-A Oklahoma City before his call up to Houston on June 3.
Carter is in his second season as an everyday player. Since the Astros jumped from the National League to the American League, he has thrived as the team's normal designated hitter. He belted 29 home runs and 82 RBIs in 2013, although he did strikeout a major league-leading 212 times. Only three other players recorded that many strikeouts at the plate.
He has 10 home runs with 27 RBIs already in 2014. Though the strikeout numbers remain high; he's already whiffed 67 times. The grand slam on Sunday was also his first hit in five games.
Like the Astros, themselves, Carter and Singleton are trying to turn their seasons around.
It sure was a grand start to that transformation on Sunday.
