Editing Roger Clemens (section)

===New York Yankees (1999–2003)===
On the first day of 1999 Spring Training, the Blue Jays traded Clemens to the [[New York Yankees]] for [[David Wells]], [[Homer Bush]], and [[Graeme Lloyd]].<ref>{{cite web | url=https://apnews.com/e56db6e613e6c4b00d6f760383a5a89c | title=Roger Clemens Traded to Yankees | website=[[Associated Press]] }}</ref> Since his longtime uniform number #21 was in use by teammate [[Paul O'Neill (baseball)|Paul O'Neill]], Clemens initially wore #12, before switching mid-season to #22.

During the 1999 regular season, Clemens posted a 14–10 record with a 4.60 ERA. He logged a pair of wins in the postseason, though he lost Game 3 of the [[1999 ALCS]] in a matchup against Red Sox ace [[Pedro Martínez]], which was the Yankees' only loss in the 1999 playoffs.<ref name=post>[https://www.baseball-reference.com/boxes/BOS/BOS199910160.shtml "Yankees at Red Sox, October 16, 1999."] ''www.baseball-reference.com.'' Retrieved February 17, 2017</ref> Clemens won the Yankees' Game 4 clincher over the [[Atlanta Braves]], giving up only one run in {{frac|7|2|3}} innings.

Clemens followed up with a strong 2000 season, in which he finished with a 13–8 record with a 3.70 ERA for the regular season. Though Clemens lost two games in the [[2000 American League Division Series#Oakland vs. New York|ALDS]] against Oakland, the Yankees won the other three and thus advanced. In [[2000 ALCS#Game 4|Game 4 of the ALCS]] against Seattle, Clemens set the ALCS record for strikeouts in a game when he fanned 15 batters in a one-hit shutout. In Game 2 of the [[2000 World Series]], Clemens pitched eight scoreless innings against the New York Mets.<ref name="Stats" />

In 2001, Clemens became the first pitcher in MLB history to start a season 20–1 (finishing 20–3), and won his sixth Cy Young Award. Clemens started for the Yankees in Game 7 of the [[2001 World Series]] against the [[Arizona Diamondbacks]], where he dueled [[Curt Schilling]] to a standstill after 6 innings, yielding only one run. The Diamondbacks went on to win the game in the 9th.

Early in 2003, Clemens announced his retirement, effective at the end of that season. On June 13, 2003, pitching against the [[St. Louis Cardinals]] in [[Yankee Stadium (1923)|Yankee Stadium]], Clemens recorded his [[300 win club|300th career win]] and 4,000th career strikeout, the only player in history to record both milestones in the same game.<ref>{{cite web |url=https://www.baltimoresun.com/news/bs-xpm-2003-06-14-0306140329-story.html |title=A milestone night for Clemens: 300 wins and 4,000 strikeouts - Baltimore Sun |website=www.baltimoresun.com |access-date=17 January 2022 |archive-url=https://web.archive.org/web/20210624084954/https://www.baltimoresun.com/news/bs-xpm-2003-06-14-0306140329-story.html |archive-date=24 June 2021 |url-status=dead}}</ref> The 300th win came on his fourth try; the Yankee bullpen had blown his chance of a win in his previous two attempts. He became the 21st pitcher ever to record 300 wins and the third ever to record 4,000 strikeouts. His career record upon reaching the milestones was 300–155. Clemens finished the season with a 17–9 record and a 3.91 ERA.

The end of Clemens's 2003 season became a series of public farewells met with appreciative cheering. His last games in each AL park were given extra attention, particularly his final regular-season appearance in [[Fenway Park]], when despite wearing the uniform of the hated arch-rival, he was afforded a standing ovation by Red Sox fans as he left the field. (This spectacle was repeated when the Yankees ended up playing the Red Sox in the [[2003 American League Championship Series|2003 ALCS]] and Clemens got a second "final start" in his original stadium.) As part of a tradition of manager [[Joe Torre]], Clemens was chosen to manage the Yankees' last game of the regular season. Clemens made one start in the World Series against the [[Florida Marlins]]; when he left trailing 3–1 after seven innings, the Marlins left their dugout to give him a standing ovation.
