Going into the start of the regular season, the Yankees were a mystery to many analysts, as the team was not expected to do much while putting up historic numbers in spring training. Masahiro Tanaka, who had put up spectacular statistics during the spring, including having pitched in a combined no-hitter, was tagged to start Opening Day against the Tampa Bay Rays, in which he'd struggle greatly. CC Sabathia pitched the second game of the young season, pulling the team to a 1–1 record, but the rest of the rotation continued to struggle. Through the team's first five games (3 at Tampa Bay, 2 at Baltimore Orioles) the Yankees were 1–4. In the third game of the series against the Orioles, the Yankees came from behind to win the game, going into their first home stand of the season having gotten their second win.

This momentum would benefit the team greatly, as the Yankees would sweep the first 2 series at Yankee Stadium (3 games against the Rays, 3 games against the St. Louis Cardinals), and taking 2 of 3 against the Chicago White Sox. The Yankees would continue to maintain this momentum through the rest of April, finishing the month with a record of 15–8.

One of the main storylines of the early season were the series of injuries the Yankees suffered. The team started the season without their shortstop, Didi Gregorius, who had maintained an injury playing in the 2017 World Baseball Classic. The team also lost rookie sensation catcher Gary Sanchez within the first five games, and Greg Bird, the first baseman who had missed the entire 2016 season, was performing abysmally, recording only six hits in his first 60 at bats. However, the team managed to work around these issues. Ronald Torreyes[3] and Austin Romine,[4] who were brought in to replace Gregorius and Sanchez, respectively, blew away the expectations placed on them and put up some of the best numbers for players at their positions. Aaron Hicks, who had struggled for much of the 2016 season played exceedingly well, Chase Headley put his lackluster performance in April of the previous season to shame, Starlin Castro hit well enough for the second-best batting average in the American League, and the rotation as a whole pitched amazingly, putting up some of the best numbers in the American League.

By far the biggest story of April, though, was rookie outfielder Aaron Judge. Having struggled in his debut season of 2016, Judge worked extensively over the offseason to adjust his mechanics, reducing his strikeouts and increasing contact rate, while honing his impressive natural power. The adjustments were wildly successful, as Judge dramatically reduced his strikeout rate, put up one of the best batting averages in the league, and tied the record for most home runs by a rookie in the month of April, with 10. He would continue his slugging ways, hit 10 home runs in April, tying a Major League record for rookies.[5]

In a very dramatic game, on Friday, April 28, 2017, the Yankees, at home facing the Orioles, struggled offensively to start the game, with starter Sabathia proving to be ineffective. At the middle of the 6th inning, the Orioles held a 9–1 lead over the Yankees. The Yankees would then put up 3 runs in the bottom of the 6th, to which the Orioles responded by adding 2 more runs, making the game 11–4. The Yankees would attempt to shorten the gap with a Jacoby Ellsbury grand slam to make it 11–8. The Yankees would then score a run in the 9th with an RBI groundout by Ellsbury, followed by a two-run shot by Castro to tie the game. Then, with one out in the bottom of the 10th, Matt Holliday won the game with a 3-run walk-off homerun, capping off an "impossible" comeback win. With it, the Yankees won their fourth come-from-behind game in which they were losing by 8-or-more runs since 2005, twice as many as the next best team.

The Yankees entered May tied with the Baltimore Orioles for first place in the AL East with a 15–8 (.652) record, much better than their 8–15 (.348) 23-game start in 2016. During the opening series of May, Jacoby Ellsbury sustained an injury that would sideline him for nearly a week after colliding into the Yankee Stadium center field wall in a game against the Toronto Blue Jays.[6] On May 2, first baseman Greg Bird was placed on the 10-day disabled list with a nagging ankle injury.[7] The next day, right fielder Aaron Judge was named Rookie of the Month for April, 2017, beating out solid performances from Boston's Andrew Benintendi and Seattle's Mitch Haniger.

On May 7, the Yankees completed a sweep of the defending-champion Chicago Cubs at Wrigley Field in Chicago with an 18-inning 5–4 victory that extended deep into the night (it lasted over six hours by the time the night was done). After closer Aroldis Chapman blew his first save of the season by allowing three runs in the bottom of the ninth, the Yankees' bullpen carried the team through another complete game's worth of extra innings. Of note in this game was the fact that the Yankees and Cubs set the MLB record for strikeouts in a single game with 48. The Yankees also set a major-league record of seven pitchers with multiple strikeouts in their appearances (Luis Severino, Dellin Betances, Chapman, Tyler Clippard, Adam Warren, Jonathan Holder, and Chasen Shreve). Following the victory (and the Washington Nationals' loss), the Yankees held sole possession of the best record in the major leagues at 20–9.

The Yankees retired Derek Jeter's No.2 jersey and played a single-admission double-header on Mother's Day, May 12.[8] The rest of the month would see the Yankees cool off, a result of struggles from Tanaka, a lower output by the offense in general, and a slow-down in the rate Judge hit homers, though he would still finish out the month with 17 homeruns on the season and the AL Rookie of the Month for May. The Yankees would compete with the Orioles for first place until the last week of the month, with the Orioles falling to third, being leapfrogged by the Red Sox. On May 31, the Yankees sat in first place with a record of 30–20 (good for the second-best AL record, behind the 1st place Houston Astros), the Red Sox sitting at 29–23 and the Orioles at 27–24.

From June 7–11, the Yankees scored 8 or more runs in 5 straight games for the first time since 1956.

On July 18 the Yankees acquired Todd Frazier, David Robertson and Tommy Kahnle in a 7-player trade with the Chicago White Sox.

On August 24, 2017, at Comerica Park the Yankees and Detroit Tigers game broke into a brawl. The altercation led to several suspensions and fines for players on both teams, with the game being labeled as the "MLB's wildest game of the 2017 season."[9]

With the Tigers up 6–3, Yankees pitcher Aroldis Chapman began to warm up in replacement for the ejected Kahnle. Yankees catcher Austin Romine and Tigers designated hitter Miguel Cabrera were standing facing each other behind the plate, as Romine was due to catch and Cabrera was due to bat. With Torres' back turned facing them, the two exchanged phrases until Cabrera stepped towards Romine, leading Romine to take off his catcher's mask. Cabrera then shoved Romine in the chest. Romine tackled Cabrera to the ground, with the two throwing punches at each other.[10] At this point, the benches on both sides cleared, and a fight formed in the center of the field. Gary Sánchez ran out from the dugout and landed punches on Cabrera and Tigers' third baseman Nicholas Castellanos before his teammate, injured Yankees' outfielder Clint Frazier, attempted to restrain Sánchez.[11] Austin Romine ended up beside his brother, Tigers infielder Andrew Romine. As the fight cleared, both Austin Romine and Cabrera were ejected from the game for their roles in the fight.[12]

In a postgame press conference, Girardi visibly expressed frustration with the umpiring crew for their mishandling of the situation, specifically the lack of a warning after Fulmer's hit on Sánchez. "If you can't see that Fulmer clearly hit Sánchez on purpose, there's something wrong. I think it could have really been avoidable."[13] He stressed the importance of the game due to the Yankees' playoff aspirations compared to the 4th-place Tigers, and cited an inconsistent strike zone at the end of the game. Regarding Romine's ejection, he said "Cabrera went after him and you're gonna throw my catcher out for protecting himself? I mean, pay attention. Somebody's gotta pay attention to what's going on in this game." He demanded additional discipline for Ausmus, rhetorically asking, "Brad Ausmus is going to say 'F-you' to one of my players? Come on, Brad. What is that?"[14]

Romine claimed that Cabrera asked him, "You got a fucking problem with me?", then took off his mask and got shoved to the ground. "It felt like he wanted a confrontation there and I just tried to defend myself the best I could."[15] Sánchez, who was seen throwing punches, stated through his interpreter that "At that moment, instinct just takes over, because you want to defend your teammate. That's your family out there."[16]

Gardner, who was involved in altercations with Ausmus and Iglesias, said "I thought the way things were handled, things got out of hand in a hurry. You'd like to see that get squashed from the start. It's not good for the game... I think any time you go through some controversy, it can bring guys together." Todd Frazier, on getting hit by Wilson, said "I thought everything was done with. I just kept asking him, 'Did you do that on purpose?' He wouldn't say a word, just kept staring at me, and that's when I got pretty excited."[17]

The next day, Major League Baseball announced discipline for the players involved in the brawl, including the suspensions of five players and managers and the finings of seven additional participants. Cabrera received the longest suspension at seven games, while Yankees catcher Sánchez received the longest suspension on his team at four games. All disciplined players had their suspensions reduced by one game following appeals.

The Yankees were swept at home by the American League-leading Cleveland team from August 28–30, after which Cleveland went on to record a historic 22-game win streak.[18]

In September, Aaron Judge broke out of a prolonged slump[19] and the Yankees pulled ahead in the American League wildcard race by winning 23 of their final 34 games. From September 11–13 a three-game series against the Tampa Bay Rays was relocated from Tropicana Field to Citi Field due to Hurricane Irma, marking the first time since 1998 that the Yankees played a game in Queens not against the Mets.[20]

The Yankees clinched a post-season berth in Toronto on September 23. The Yankees continued their 6-man starting rotation throughout the month. Both relief pitchers Dellin Betances and Aroldis Chapman showed some struggles during this month.

On September 25 in a makeup game against the Kansas City Royals, Aaron Judge tied and broke the MLB rookie record for home runs hit in a single year. In doing so, he also became the youngest player to have 7 multi-home run games in Yankee history since Babe Ruth and Mickey Mantle.

In the month of September, a documented phone conversation between Yankees pitching coach Larry Rothschild and replay room officials revealed that Yankees had inappropriately used a dugout phone to obtain information on pitch selection; this resulted in the team being fined.[21][22]

Yankees won the AL Wild Card Game 8–4. Yankees rallied from trailing 0–2 to rally to win the ALDS in 5 games against Cleveland Indians. Yankees also trailed the ALCS 0–2 and were 1 win away from heading to the World Series but failed and lost in 7 against the Astros. On October 26, 5 days after the Yankees were eliminated the team announced that they would not bring back Joe Girardi for the 2018 season.
