For much of the season, 2010 was frequently labeled the Year of the Pitcher (though this title is also taken by the 1968 season).[1][2] 2010 saw many significant pitching achievements, including:
Six no-hitters were thrown. They were thrown by Ubaldo Jiménez (April 17), Dallas Braden (May 9), Roy Halladay (May 29), Edwin Jackson (June 25), Matt Garza (July 26), and Halladay again, this time in Game 1 of the NLDS. It was only the third time in major league history that at least six no-hitters were thrown in a single season. Braden's no-hitter and Halladay's first were both perfect games.
Armando Galarraga's near-perfect game (June 2), in which Galarraga set down the first twenty-six Cleveland Indians batters in order before umpire Jim Joyce incorrectly ruled Jason Donald safe at first on a ground ball. If not for Joyce's mistaken call, Galarraga's would have been the third perfect game in a season (an MLB record, but it was later done in 2012 by Philip Humber, Matt Cain, and Félix Hernández), and the third in less than a month.
MLB pitchers combined for 329 shutouts (the most since 1972, when there were 357) and a record 34,306 strikeouts (an average of 1,144 per team).[3][4]

Threw the 19thperfect game in Major League history, defeating the Tampa Bay Rays 4–0 on May 9, Mother's Day in the USA. Symbolically and coincidentally (as he had lost his mom to breast cancer while in high school), players wore pink wristbands and ribbons on this day to raise breast cancer awareness. It was also the second perfect game in Oakland A's history; the first coming on May 8, 1968, when Jim "Catfish" Hunter beat the Minnesota Twins, 4–0.
Exactly 20 days later, on May 29, Halladay threw the 20th perfect game in Major League history, defeating the Florida Marlins 1–0. This achievement marked the first time in the modern (post-1900) era that two perfect games were pitched in the same season. In 1880, both Lee Richmond and John Montgomery Ward both hurled a perfect game five days apart. It was also the first perfect game for the Phillies since Jim Bunning's Father's Day perfect game on June 21, 1964, beating the New York Mets, 6–0.
Galarraga threw what would have been a third perfect game on June 2 against the Cleveland Indians. However, first base umpire Jim Joyce made an errant call on Galarraga's coverage of first base on a flip throw by first baseman Miguel Cabrera, which would have been the final out. "I just cost [Galarraga] a perfect game", Joyce replied. "I thought he beat the throw. I was convinced he beat the throw, until I saw the replay. It was the biggest call of my career. I don't blame them a bit or anything that was said. I would've said it myself if I had been Galarraga. I would've been the first person in my face, and he never said a word to me." The 17,738 fans—as well as players and manager Jim Leyland—argued following the game.[13]

The Florida Marlins, as part of the team's rebranding to the Miami Marlins as part of their preparation for the 2012 opening of their new ballpark, has dropped "Florida" from their road uniforms that had been with the team since its inception, using the team name instead.
The Minnesota Twins became the first team to unveil changes for the season. On November 16, 2009, the team unveiled a new logo with a revamped wordmark, and introduced throwback alternates based on their 1961 home uniforms, which were worn on Opening Day and on Saturdays. The Twins also unveiled their first road uniform change since 1987, dropping the pinstripes, and changing to a script "Minnesota" with lettering and numbering in navy with white and red trim. The new wordmark also appears on a revamped logo, with a baseball design and the words "Minnesota Twins Baseball Club" incorporated onto a navy circle.
The Milwaukee Brewers debuted a road alternate jersey with "Milwaukee" on the front, marking the first time the city name will appear on a road jersey since 1999.[47]
The New York Mets introduced an alternate pinstripe home uniform for the 2010 season. The new uniforms are cream-colored instead of white, and are based on the original Mets uniform, when the team debuted in 1962. The Mets continue to wear their non-pinstriped white uniforms and their black alternate jerseys at Citi Field as well.
The San Francisco Giants unveiled an orange alternate jersey for 2010 worn on "Orange Friday" games at home. The jersey will have the Giants name in black with a white outline along with a two-stripe black trim around the neck and sleeves. The team also changed their socks, adding three orange stripes to the black stockings already worn (while not wearing their "pajama pants.")

The San Francisco Giants retired the #20 worn by Monte Irvin, one of the first African-American pioneers in Major League Baseball, on June 26 prior to their game against the Boston Red Sox at AT&T Park. Irvin, with Hank Thompson, were the first black players to play for the franchise while the team was based in New York in 1949.[48]

The Chicago White Sox retired Frank Thomas' #35 on August 29 before their game against the New York Yankees. "The Big Hurt" officially retired as a White Sox member on February 12.[52] The Pale Hose also unretired the #11 made famous by Luis Aparicio and allowed Omar Vizquel to wear it this season.[53] This is due to the fact that manager Ozzie Guillén already wears number 13, which Vizquel has worn through his career in tribute to Dave Concepción.
To celebrate their 40th Anniversary season in Milwaukee, the Brewers wore replicas of their previous uniforms during three home games, first donning their 1972 uniforms on May 14 versus the Philadelphia Phillies, who wore replicas of their powder blue outfits that night; their 1982 uniforms against the Seattle Mariners on June 25, who donned their pullovers from that season, and their 1998 uniforms against the Washington Nationals on July 23.

The Houston Astros, in honor of their 45th year as the Astros, wore their 1965 jerseys on April 10 against the Phillies, who also wore replicas of their 1965 uniforms on that date. In addition, members of the ground crew donned replicas of the "spacesuits" worn by groundskeepers at the Astrodome and several female members were attired in replicas of the Astros' usherettes uniform. The team wore their "Rainbow Shoulders" uniform worn from 1985 through 1995 against the Cincinnati Reds July 24 as well.
For the Civil Rights Game May 15, the Cincinnati Reds and St. Louis Cardinals wore replicas of their uniforms from 1954, the year in which both teams fielded their first black players.
The San Diego Padres held "Throwback Thursdays", featuring the uniforms worn in both 1978, when the team recorded their first winning record, and from 1984, when the team won their first pennant in the National League. Several teams – notably the Atlanta Braves and the Pittsburgh Pirates – joined in by wearing replicas from that season.
The Orioles wore an all-orange uniform on August 13 at the Tampa Bay Rays, who donned uniforms of the Tampa Tarpons from that 1970 season as well. Orioles skipper Buck Showalter criticized the uniforms, and said they will never wear them again for a turn back the clock game.
The Nationals and Cleveland Indians wore throwback uniforms on June 12 to commemorate each city's first World Series wins in 1920 and 1924, respectively (the Washington team were then the American League Washington Senators franchise).

Due to the 2010 G-20 Toronto Summit, the Toronto Blue Jays along with Major League Baseball decided to hold their three-game interleague series with the Philadelphia Phillies at Citizens Bank Park rather than at Rogers Centre on June 25 through 27 as originally planned. This series was played under American League rules with a Designated Hitter and the Blue Jays as the home team for both scoring and statistical purposes. It was the first time the Designated Hitter rule was used in a National League ballpark (other than exhibition games and all-star games) since Game 2 of the 1984 World Series. As a result, during the 2011 season, the Phillies will visit Rogers Centre on Canada Day weekend (July 1 through 3).
