He played in Major League Baseball as a center fielder from 1962 through 1973, most notably as a member of the New York Mets team that became known as the Miracle Mets when, they rose from being perennial losers to defeat the favored Baltimore Orioles in the 1969 World Series for one of the most improbable upsets in World Series history.

[1] Agee performed two impressive defensive plays in center field to help preserve a Mets victory in the third game of the series.

[2] Agee was born in Magnolia, Alabama, and played baseball and football at Mobile County Training School with future New York Mets teammate Cleon Jones.

After two seasons in the Indians' farm system with the AAA Portland Beavers, Agee received a September call-up to Cleveland in 1962.

With the Indians already behind 11-1 to the Minnesota Twins, Agee made his major league debut on September 14 at Metropolitan Stadium pinch-hitting for pitcher Bill Dailey in the ninth inning.

After earning the starting center fielder job in spring training 1966, he hit a two-run home run in the season opener,[5] and was batting .264 with nine home runs and 38 RBIs to be named the White Sox's sole representative at the 1966 Major League Baseball All-Star Game.

To alleviate this problem, the White Sox imported perennial .300 hitter Tommy Davis, along with pitcher Jack Fisher and two minor leaguers, from the New York Mets for Agee and Al Weis.

To commemorate the home run, there was a painted sign in that section of the stadium with Agee's name and uniform number and the date.

This was followed by a five-game losing streak that saw the Mets fall into fourth place in the newly aligned National League East.

Cubs starter Bill Hands knocked down the first batter he faced, Agee, who had been moved into the lead-off spot in the line-up, in the bottom half of the first inning.

Agee batted .357 with two home runs and four RBIs in the Mets' three-game sweep of the Atlanta Braves in the 1969 National League Championship Series.

Agee, playing the left-handed hitting Elrod Hendricks to pull, made a backhanded catch near the base of the wall in left centerfield.

The second catch came in the seventh inning with Nolan Ryan relieving Gentry; the bases were loaded with two outs, and Agee made a headfirst dive in right centerfield on a ball hit by Paul Blair.

Agee was traded from the Mets to the Houston Astros for Rich Chiles and Buddy Harris at the Winter Meetings on November 27, 1972.

[22] He was batting .235 with eight home runs and 15 RBIs when the Astros dealt him to the St. Louis Cardinals on August 18, who were in a battle with the Mets and Pittsburgh Pirates in the NL East.

Agee was also known as the most active former Met, taking part in many charitable events and children's baseball clinics around both the New York area and Mobile.
