TBS televised the games in the U.S.[1][2] This was the second time in LCS history, and second year in a row, that two wild card teams faced each other.

For the third straight full season, a team with less than 90 wins won the NLCS, as the 84-win Diamondbacks pulled off the upset to defeat Philadelphia in seven games.

Kelly's replacement, Joe Mantiply, gave up a two-run double to J. T. Realmuto to give the Phillies a five-run lead.

The first six innings of Game 3 consisted of a scoreless pitcher's duel between Arizona's Brandon Pfaadt and Philadelphia's Ranger Suárez.

Pfaadt was pulled in the sixth after striking out Brandon Marsh, a decision that was heavily booed by fans at Chase Field.

Arizona's Paul Sewald worked around a Harper walk and stolen base to send the game to the bottom of the ninth, where closer Craig Kimbrel was sent in for the Phillies.

[15] In the bottom of the second inning, Christian Walker scored on a single by Emmanuel Rivera to stake the Diamondbacks to an early 1–0 lead.

Alec Bohm hit a two-run single off Ryan Thompson in the sixth to give Philadelphia a 4–2 lead.

With Arizona trailing by two runs in the bottom of the eighth, Philadelphia closer Craig Kimbrel gave up a double to Lourdes Gurriel Jr. With one out, pinch-hitter Alek Thomas hit a two-run home run into the Chase Field pool to tie the game at five.

After striking out Perdomo, Kimbrel gave up a single to Marte and hit Corbin Carroll with a pitch.

In the top of the first, Bryson Stott singled off Gallen to score Kyle Schwarber to give the Phillies the early lead.

In the bottom of the seventh, Alek Thomas hit a home run off Zack Wheeler to put the Diamondbacks on the board cutting their deficit to three.

In the top of the eighth, J. T. Realmuto hit a two-run home run off Luis Frías to extend the Phillies lead to 6–1.

Tommy Pham and Lourdes Gurriel Jr. led off the second inning with back-to-back home runs to take a 2−0 lead.

Alek Thomas walked and scored when Evan Longoria doubled to left center field, giving the Diamondbacks a 3−0 lead.

Corbin Carroll singled in the fifth inning and would later score on a Ketel Marte triple to extend the Diamondback lead to 4−1.

Marte tied a Major League record to start a postseason career with Marquis Grissom with 15 straight games with a hit.

Ryan Thompson, Andrew Saalfrank, and Kevin Ginkel pitched scoreless sixth, seventh, and eighth innings to preserve the Diamondbacks lead.

In the bottom of the fourth, Bryson Stott doubled home Bohm to give the Phillies a one-run lead.

In the top of the fifth, Corbin Carroll’s RBI single scored Emmanuel Rivera tying the game at two apiece.

[18][19][20] The Phillies were the first NL team with home-field to win the first two games of an NLCS and drop the series since the Dodgers did so against Cardinals in 1985.

It was the longest hit streak in postseason history by 3 games; the previous high of 17 was accomplished by Hank Bauer (1956-58), Derek Jeter (2003-04) and Manny Ramirez (2003-04).
