The Mets score again in the twentieth on a sacrifice fly by José Reyes to win the game, 2–1. The Mets use 24 of the 25 men on their roster.

The last was the Cincinnati Reds' Paul Wilson in {{baseball year|2005}}.
• April 20 – At Fenway Park, Darnell McDonald pinch-hits a two-run home run to tie the game in the eight inning and a walk-off single in the ninth to push the Boston Red Sox to a 7–6 victory over the Texas Rangers.

• April 21 – The Chicago Cubs confirm reports that manager Lou Piniella is moving struggling starter Carlos Zambrano to the bullpen, in a move that may not be temporary. Zambrano is 1–2 with a 7.45 ERA in four starts, and the move makes room for Ted Lilly, who is returning to the Cubs' starting rotation after undergoing offseason shoulder surgery.

• April 22

Zambrano gave up a run in {{frac|1|1|3}} innings and had a sacrifice fly in Chicago's three-run eighth.
• April 26 – The Philadelphia Phillies sign Ryan Howard to a five-year, $125 million contract extension that will keep Howard with the Phillies through 2016.

• April 28 – Commissioner Bud Selig's special committee for on-field matters expands All-Star rosters again, with each team bringing 34 players, with 13 pitchers per team, to the July 13 game at Angel Stadium in Anaheim, California, as part of several changes. Another change is that a pitcher who starts on the final Sunday before the All-Star break will be ineligible to pitch in the ASG and will be replaced on the roster. In addition, a designated hitter will be used in the ASG every year, including in National League cities; the AL's starting DH will continue to be elected by fans, and the NL's starting DH will be chosen by the NL All-Star manager. Under a change that runs contrary to normal baseball rules, each manager may designate a position player who will be eligible for re-entry to the game if the final position player, at any position, is injured.^[4]
• April 29 – A new report shows Major League Baseball equaled its best grades for racial and gender diversity hiring, even as the percentage of African American players dropped again in 2009, from 10.2 percent to 9 percent. The sport had made a small stride since reaching a low of 8.2 percent in 2007, but the latest data indicates a steady rise in the percentage of black players might be years away.^[5]
• April 30 – Johnny Damon becomes the 68th player to score 1500 runs. He is batted in by Magglio Ordóñez' sacrifice fly.

Ramos followed his debut by going three-for-four and driving in his first run on May 3.
• May 3
  • New York Yankees second baseman Robinson Canó and Minnesota Twins starter Francisco Liriano are named the American League Player and Pitcher of the Month for April, respectively. Canó hit a Major League-best .400 batting average, including eight home runs, 21 runs scored and 18 RBI. Liriano went 3–0 and finished as the only AL starter with a sub-1.00 ERA (0.93) in 29 innings, which included a 23-inning scoreless streak.^[6]

Jiménez, who posted a 5–0 record with 31 strikeouts and a 0.79 ERA in {{frac|34|1|3}} innings of work, also hurled the first no-hitter in Rockies history.^[7]
• May 6 – In Round Rock, Texas, the Express debut a new pitcher named Billy Ray "Rojo" Johnson, who in reality was actor Will Ferrell in disguise.
• May 7
  • At Citizens Bank Park, Jamie Moyer becomes the first pitcher to throw a shutout in four separate decades, giving up only two hits in the Philadelphia Phillies's 7–0 victory over the Atlanta Braves. At 47 years, 170 days old, Moyer is also the oldest pitcher to throw a Major League shutout, eclipsing Phil Niekro's record by almost a year. At 46 years, 188 days old, Niekro, while pitching for the New York Yankees, tossed a four-hit shutout against the Toronto Blue Jays on October 6, {{Baseball year|1985}}; the shutout was also Niekro's 300th career victory.^[8]
  • Starlin Castro of the Chicago Cubs becomes the first player born in the 1990s to play in the majors. Castro arrives in historic style, hitting a three-run home run in his first at-bat and a bases-loaded triple, sliding head-first into the record books with six runs batted in, the most ever in a modern-day debut. Chicago defeats the Cincinnati Reds, 14–7, while the 20-year-old rookie becomes the youngest shortstop in Cubs history, surpassing Marty Shay, who was 100 days older when he made it to the majors in {{baseball year|1916}}.^[9]

• May 9 – On Mother's Day, with his grandmother in attendance, Dallas Braden of the Oakland Athletics pitches a 4–0 perfect game against the Tampa Bay Rays at Oakland–Alameda County Coliseum. The perfect game is the second in Athletic history. Catfish Hunter had thrown the first, 42 years and one day earlier, on May 8, {{Baseball year|1968}}, also by a 4–0 score at Oakland–Alameda County Coliseum. It is also the first no-hitter by an Athletic pitcher since Dave Stewart in {{Baseball year|1990}}, and the first complete game of Braden's career. The Tampa Bay Rays had been the victim of the last perfect game in the Majors, by Chicago White Sox pitcher Mark Buehrle on July 23, {{mlby|2009}}.
• May 11 – Due to the pending G-20 Summit to be held in Toronto, Ontario, Canada that weekend, the Philadelphia Phillies–Toronto Blue Jays series is moved from Rogers Centre to Citizens Bank Park. For statistical purposes, the Blue Jays serve as the home team and use the designated hitter rule in this interleague series. This marks the first time the Phillies have played the Blue Jays in Toronto since the 1993 World Series.
• May 13
  • Mat Latos comes extremely close to pitching a no-hitter, but has to settle for a one-hit shutout and the first complete game of his career, as the San Diego Padres beats the San Francisco Giants, 1–0. The only hit Latos allows is a ground ball by Eli Whiteside in the 6th inning that glances off him towards third baseman Chase Headley, whose throw to first base is a fraction too late to retire Whiteside. For good measure, Latos also drives in the only run of the game.
  • Zack Greinke finally earns his first win of the year, but it comes too late to save Kansas City Royals manager Trey Hillman. The Royals announce after their 6–4 win over the Cleveland Indians that Hillman has been fired and will be replaced by former Milwaukee Brewers manager Ned Yost. At the time, the Royals are 12-23 and in a familiar last place in the AL Central Division.
• May 19 – Center fielder Ángel Pagán hits an inside-the-park home run and starts a triple play, but it is not enough for the New York Mets in a 5–3 loss to the Washington Nationals. Pagán becomes the first player in 55 years to take part in both feats in the same game. Philadelphia Phillies shortstop Ted Kazanski was the last player to do both, on September 25, {{baseball year|1955}} against the New York Giants.^[10]
• May 20 – After trailing 9-3 against the Cincinnati Reds, the Atlanta Braves score seven runs in the bottom of the 9th inning, all topped off by a walk-off grand slam from pinch hitter Brooks Conrad.
• May 27 – The New York Mets complete a three-game sweep of the Philadelphia Phillies in which Philadelphia is shut out all three games. The last time the Mets accomplished such a feat was September 26–28, {{baseball year|1969}} also against the Phillies.
• May 29 – At Sun Life Stadium, Roy Halladay of the Philadelphia Phillies pitches a 1–0 perfect game against the Florida Marlins. With Oakland's Dallas Braden having pitched a perfect game on May 9, this season is the first in modern history to witness two perfect games.^[11] Halladay strikes out 11 in his masterpiece, the second perfect game in Phillies history. Jim Bunning had pitched the first, on June 21, {{baseball year|1964}}. The home plate umpire is Mike DiMuro, whose father Lou had been home plate umpire for Jim Palmer's no-hitter in {{Baseball year|1969}}.
• May 30
