Freddie Freeman put the bitter ending to last season behind him with a walk-off, two-run home run that clinched a National League playoff berth for the Atlanta Braves on Tuesday.
Freeman blasted the game-winner to give the Braves a 4-3 win over the Miami Marlins, one year after he made the final out of the season that saw the team blow an 8 1/2-game lead in the wild card race.
"This is the coolest thing I've ever had happen to me in my life," Freeman told reporters after being mobbed by team mates celebrating Atlanta's return to the post-season.
"This is a dream come true. I just don't know what to say."
Atlanta (89-65) still have a chance to catch NL East leaders Washington, who they trail by four games.
In Houston, the St Louis Cardinals moved closer to sealing a playoff berth with a 4-0 win against the Houston Astros.
Jaime Garcia fired seven scoreless innings and the Cardinals (84-71) moved 4 1/2 games in front of Milwaukee (79-75) in the race for the National League's second wild card berth.
The Brewers fell 4-2 in Cincinnati as their hopes are looking slim with just eight games remaining.
In San Diego, the Los Angeles Dodgers also saw their playoff chances suffer after a 2-1 defeat dropped them 4 1/2 games adrift of a post-season spot.

"It's definitely a lot of fun," Angels outfielder Torii Hunter told reporters of the post-season chase.
