It's official: The Boston Red Sox will have the No. 4 overall pick in the 2021 MLB Draft. Here's a look at some of the best No. 4 picks in MLB history.

Munson wasted no time making his presence felt in New York after being drafted fourth overall in 1968. The legendary catcher quickly burst on the scene as a top prospect and earned American League Rookie of the Year honors in 1970.
During his 11-year MLB career, Munson helped the Yankees to two World Series titles, won an MVP award in 1976, and earned three consecutive Gold Gloves. He was an integral part of New York's success all the way up until his untimely death in 1979 at the age of 32.

Winfield is right up there with Tony Gwynn and Trevor Hoffman as one of the best players in San Diego Padres history. The Hall-of-Fame outfielder was a 12-time All-Star, seven-time Gold Glover, and six-time Silver Slugger. He also helped the Blue Jays to a World Series title in 1992.
Winfield finished his 23-year MLB career with 3,110 hits and 465 home runs.

Larkin quickly ascended to the major leagues after being selected by the Cincinnati Reds in the 1985 draft. The shortstop made his debut in '86, then went on to enjoy a career in which he earned 12 All-Star selections, three Gold Gloves, nine Silver Sluggers, and an NL MVP.
Larkin helped the Reds to a World Series title in 1990 and spent his entire 19-year career with Cincinnati.

Brown joined the Texas Rangers' starting rotation full-time in 1989, when Nolan Ryan was Texas' ace. In Texas, Brown notched a 78-64 record and a 3.81 ERA.
A six-time All-Star, he went on to enjoy most of his success with the Florida Marlins, finishing as the NL Cy Young runner-up in 1996 and helping them to a World Series title in '97.

Wood made his MLB debut in 1998 and finished that season as the NL Rookie of the Year with a 13-6 record, 3.40 ERA and 233 strikeouts. In his fifth career start, Wood had arguably the greatest pitching performance of all time: a one-hit, no-walk, 20-strikeout shutout against the Houston Astros.
Injuries were an issue for Wood throughout his 14-year career, but his talent was undeniable. He transitioned to a closer role in 2007 due to his injuries and saw success in that role with 63 career saves.

Zimmerman has been considered the heart and soul of the Nationals since being selected in the 2005 draft. He was the team's first ever draft pick when the franchise moved from Montreal.
The only active player on this list, Zimmerman has spent his entire 15-year career in Washington. He's a two-time All-Star who became a World Series champion in 2019 and hit the first World Series home run in Nationals franchise history.
