1969 National League Championship Series

New York won the series, 3–0.

In Game 1, the top 2 Cy Young candidates faced off with the eventual winner Tom Seaver taking the mound for New York, while the Braves sent out Phil Niekro, who was the only other pitcher to receive a Cy Young vote in the NL, behind Seaver. The Mets struck first in the second off Niekro when Jerry Grote singled in a run with two on and Ken Boswell scored on a passed ball by Braves catcher Bob Didier. The Braves cut the lead in half in their half on a sacrifice fly by Clete Boyer with runners on second and third off of Seaver.

The Braves took a 3–2 lead in the third inning scoring twice on three consecutive one-out doubles by Felix Millán, Tony González, and Hank Aaron. The Mets immediately re-took the lead in the fourth inning on a two-run triple by Bud Harrelson after a two-out single and walk.

Gonzalez then tied the game at 4–4 in the fifth inning with the first home run in NLCS play. Hank Aaron gave the Braves the lead with a home run in the seventh.

In the eighth, however, things fell apart for the Braves. Wayne Garrett led off with a double and was singled home by Cleon Jones. Art Shamsky singled and Jones stole third. Ken Boswell then grounded to first, but Braves first baseman Orlando Cepeda threw wildly home in an attempt to retire Jones. Boswell reached first and Al Weis, running for Shamsky, went to second. Ed Kranepool forced Weis at third, and Grote grounded out to first, putting runners on second and third. Harrelson was walked intentionally to load the bases. Then, J.C. Martin, batting for Tom Seaver, drove in two runs with a single to right center. Harrelson came around to score from first when González misplayed the hit. Martin reached second, but was cut down in a rundown. Ron Taylor pitched two shutout innings to close it out as the Mets won the first NLCS game in history.

For the second game, the Braves started 25 year old Ron Reed, making his postseason debut, while the Mets started Jerry Koosman, another young up and coming pitcher behind their ace Tom Seaver. The Mets scored early and often in this one, pounding six Braves pitchers for 13 hits and 11 runs. Ed Kranepool brought in the first run in the top of the first with a bases-loaded single. Tommie Agee's two-run home run after a walk next inning extended the Mets' lead to 3–0. Cleon Jones doubled with two outs and scored on Art Shamsky's single to knock Reed out of the game. Next inning off of Paul Doyle, Jerry Grote reached on an error before scoring on Bud Harrelson's double. After a two-out intentional walk, Wayne Garrett's RBI single made it 6–0 Mets. Ken Boswell's two-run home run off of Milt Pappas made it 8–0 Mets. The Braves got on the board in the bottom half off of Koosman when Rico Carty doubled with one out and scored on Orlando Cepeda's single. In the top of the fifth, Garrett doubled and scored on Jones's single. In the bottom half, Koosman got two outs before allowing a single and walk, then Hank Aaron's three-run home run cut the Mets' lead to 9–4. After a walk and double, Clete Boyer's two-run single brought the Braves within three. However, Ron Taylor, who earned the win, and Tug McGraw held them scoreless for the rest of the game while Jones's two-run home run in the seventh off of Cecil Upshaw extended the Mets' lead to 11–6. They took a 2–0 series lead heading to New York.

For the pivotal Game 3, Atlanta started Pat Jarvis, while New York started rookie Gary Gentry (on his 23rd birthday). In what would be his last postseason appearance, Hank Aaron put the Braves up 2–0 in the first inning with a two-run home run, his third of the series, off of Gentry, who only lasted 2 innings.

Once again, the downfall of the Braves was their inability to stave off the hot Met hitters. Tommie Agee homered in the third, and Ken Boswell hit a two-run home run in the fourth to put the Mets on top 3–2 off of starter Pat Jarvis.

Orlando Cepeda gave Braves fans a glimmer of hope by hitting a two-run home run off Nolan Ryan in the fifth after a two-out walk to put the Braves back on top, 4–3. But, in the bottom of the inning Ryan singled with one out and Wayne Garrett then homered to give the Mets a 5–4 lead, which they would not lose. Cleon Jones's double knocked Jarvis out of the game. Boswell added an RBI single off of George Stone, and next inning, Jerry Grote hit a leadoff double off of Stone and Agee singled him home off of Cecil Upshaw. Ryan pitched seven innings in relief of Gentry for the win as the Mets advanced to their first World Series.
