2018 Chicago Cubs season

The 2018 Chicago Cubs season was the 147th season of the Chicago Cubs franchise, the 143rd in the National League and the Cubs' 103rd season at Wrigley Field. The Cubs were managed by Joe Maddon, in his fourth year as Cubs manager, and played their home games at Wrigley Field as members of Major League Baseball's National League Central.

The Cubs began the season March 29 at the Miami Marlins and finished the season on September 30 against the St. Louis Cardinals. On September 26, the Cubs clinched a trip to the postseason for the fourth year in a row, marking the longest streak in franchise history. The Cubs finished the 162-game schedule 95–67, earning a tie with the Milwaukee Brewers for the division and the best record in the National League. They lost to the Brewers in a 163rd game to determine the Central Division champions, failing in their quest to win the division for a third consecutive year. Instead, they hosted the NLWC Game against the Colorado Rockies, but the Cubs lost 2–1 in 13 innings.

Previous season

The Cubs finished the 2017 season 92–70 in first place in the Central Division, winning the division title for the second consecutive year. The Cubs defeated the Washington Nationals in the National League Division Series three games to two to advance to face the Los Angeles Dodgers in the League Championship Series in a rematch of the previous year's series. In the best of seven NLCS, the Cubs lost to the Dodgers four games to one.

Television broadcasts

The 2018 season was the second of the last for team broadcasts on long time FTA broadcaster WGN-TV, the 2018-19 offseason was when it was announced that effective Opening Day 2020, the Cubs will be moving to a brand new regional cable TV channel, making them the 4th team overall to have their own cable station, officially ending a 7-decade long presence there. WLS-TV, the team's secondary over the air broadcaster, will soon take over the free to air broadcasts of Cubs games from that year on.

Offseason

Wrigley Field renovations

The fourth phase of the 1060 Project off-season improvements began after the end of the 2017 season. Construction was started under the seats behind home plate on the first of four premier luxury clubs to be located around the park. The players dugouts have been relocated further down the left and right field foul lines to accommodate two of the four new clubs. The final club, located in the upper level, is planned for the 2019 season. The Hotel Zachary, just across Clark Street, celebrated its opening along with the Cubs' home opener against the Pittsburgh Pirates on April 9, 2018.

February

• February 27 – Cubs announced Jon Lester will be the opening day starter on March 29 against the Miami Marlins.

March

• March 29 – On Opening Day, Ian Happ homered on the first pitch of the game while Anthony Rizzo and Kyle Schwarber each hit solo home runs. Jon Lester struggled and could not make it out of the fourth, but the bullpen pitched 5.2 scoreless innings as Tommy La Stella hit a pinch-hit two-run double in the seventh to give the Cubs the 8–4 win.
• March 30 – Kyle Hendricks allowed one run over six innings, but the Cubs only managed one run in support. In a game that lasted 17 innings, Eddie Butler pitched seven innings of relief before leaving in the 17th and being replaced by Brandon Morrow, in his Cub debut, who allowed the game-winning hit. The Cubs fell to the Marlins 2–1, striking out 20 times in the game.
• March 31 – Yu Darvish made his Cub debut, but struggled, giving up five runs in 4.1 innings. The Cub bullpen came through again against the Marlins, pitching 5.2 innings of one-run relief, but the game still went to extra innings. Ben Zobrist drove in the go-ahead run in the 10th and Kris Bryant cleared the bases with a double to give the Cubs the 10–6 win.

April

• April 1 – In the final game of the opening series against Miami, José Quintana took a no-hitter into the fifth inning before falling apart and allowing six runs. The Cub bats were quiet again, failing to score as the Cubs lost 6–0.

• September 27 – With the Brewers off, the Cubs pushed their division lead to one game as Jon Lester pitched six innings of scoreless baseball.

• September 30 – Needing to win to at least force a tiebreaker game for the division, the Cubs fell behind early as Mike Montgomery gave up two runs in the first and left in the third inning. The Cubs tied it in the third on a triple by Ben Zobrist to knock in Daniel Murphy. Zobrist then scored on a wild pitch to tie the game. After a walk to Javier Baez, Anthony Rizzo doubled to score Baez and give the Cubs the 3–2 lead. Jason Heyward then drove in Rizzo with a groundout following an intentional walk to Kris Bryant to extend the lead to 4–2. Two innings later, Bryant drove in two on a double and Willson Contreras homered to give the Cubs an 8–2 lead. The Cubs coasted from there, winning 10–5.

Wild Card game

Following their loss to the Brewers the previous day, the Cubs faced the Rockies who were forced to travel from Los Angeles following their tiebreaker loss to the Dodgers to face the Cubs in Chicago on October 2. The Rockies scored in the first on two hits and a sacrifice fly giving the Rockies a 1–0 lead. Jon Lester, despite giving up the first inning run, pitched six innings and allowed only the one run. Rockies' pitcher Kyle Freeland pitched well, limiting the Cubs to four hits in 6.2 innings of work. Freeland left in the seventh with a runner on. The Cubs eventually loaded the bases via a walk and Tommy La Stella reaching on a catcher's interference. However, Jason Heyward struck out as a pinch hitter to end the threat. Following a two-out single by Anthony Rizzo in the eighth, Rizzo was lifted for pinch-runner Terrance Gore who immediately stole second. Javier Baez then doubled in Gore to tie the game. However, Albert Almora Jr struck out to end the threat. Following a quiet ninth inning, the game proceeded to extra innings. Cole Hamels entered the game for the Cubs and allowed a single in the 10th and a single and walk in the 11th, but did not give up a run. The Cubs put runners on first in second with one out in the 11th, but could not push across a run. Kyle Hendricks entered the game in the 12th and, in the 13th with two outs, gave up three straight singles to give the Rockies the 2–1 lead. The Cubs went quietly in the 13th as they lost the game 2–1.
