Alois Terry Leiter (/ˈlaɪtər/; born October 23, 1965) is an American former professional baseball player and current television sports commentator.

A two-time National League (NL) All-Star player, Leiter pitched for three World Series winning teams and threw a no-hitter in 1996 during his tenure with the Marlins.

As a member of the New York Mets, Leiter was named the recipient of the prestigious Roberto Clemente Award in 2000.

Leiter has mentioned on a YES Network broadcast that early in his career with the Yankees, manager Billy Martin walked up to him and asked him why he was lifting weights.

The young Leiter grew nervous easily; teammate Tommy John observed "If they had named him to start on opening day [in 1989], he wouldn't have slept for a week.

"[5] In one of his final starts as a young player for the Yankees, manager Dallas Green left Leiter in to throw 162 pitches on a cold damp day in 1989.

[citation needed] Leiter finally got over his injury troubles in 1993, making 32 appearances (12 starts) for the Blue Jays.

Leiter started Game 7 for the Marlins, pitching 6 innings and giving up two earned runs while being credited with a no decision.

He was booed by Yankee fans when presented that year's Roberto Clemente Award prior to Game 2 of the World Series.

[10] On April 30, 2002, Leiter became the first Major League pitcher to defeat all 30 teams, after beating the Arizona Diamondbacks 10–1.

In 17 appearances (16 starts), he had a 3–7 record and a 6.64 ERA, and he took much criticism for the Marlins' first-half struggles in 2005 (they were 7 games behind the surprising Washington Nationals at the All-Star break).

On July 10, when the Marlins played their last game before the three-day All-Star break, he gave up six runs in three-plus innings.

On July 15, 2005, Leiter was acquired by the New York Yankees, who had four starting pitchers on the disabled list, for a player to be named later.

[13] In his final official appearance in a Major League uniform, Leiter earned a win, pitching 2⁄3 scoreless innings in Game 4 at Yankee Stadium.

The primary reason he spent part of spring training with the Yankees was to keep in shape for the World Baseball Classic.

After the United States team was eliminated from the World Baseball Classic, he officially retired in an interview on YES, after a Yankees spring training victory versus the Indians where Leiter pitched 1⁄3 of an inning.

[14] Al Leiter has worked in the television broadcast booth for Fox during the playoffs for several seasons, mainly to provide in-depth analysis of various pitchers.

The following year, Leiter was in the booth with Joe Buck and Tim McCarver for the Boston Red Sox Vs. NY Yankees in the ALCS.

Leiter has expressed interest in running for political office as a Republican in his home state of New Jersey.

[17] Leiter has donated thousands of dollars to GOP candidates, including Donald Trump, David Perdue, Kelly Loeffler, Lindsey Graham, Chris Christie, and Rudy Giuliani.

[19] He and his wife Lori have four children: three daughters, Lindsay, Carly and Katelyn, and one son, Jack (who made his MLB debut with the Texas Rangers in 2024).
