If I had an unlimited budget and was tasked with assembling the best possible baseball team with players from all eras, taking into consideration both offensive and defensive ability, here is the team I would create:
Pitcher: Sandy Koufax. Koufax is widely considered to be one of the greatest pitchers of all time, and he would be the ace of any pitching staff. He won three Cy Young Awards and four World Series championships, and he had a career ERA of 2.76.
Catcher: Johnny Bench. Bench is one of the greatest catchers in baseball history, and he would be a great asset to any team. He won 10 Gold Gloves and two MVP awards, and he was a key member of the Cincinnati Reds' Big Red Machine teams of the 1970s.
First Base: Albert Pujols. Pujols is one of the greatest hitters of all time, and he would be a force at the plate for any team. He has won three MVP awards and two World Series championships, and he has a career batting average of .328 with 683 home runs.
Second Base: Roberto Alomar. Alomar is one of the greatest second baseman in baseball history, and he would be a great addition to any infield. He won 10 Gold Gloves and two World Series championships, and he was a smooth fielder with a great bat.
Third Base: Mike Schmidt. Schmidt is one of the greatest third baseman in baseball history, and he would be a great addition to any infield. He won 10 Gold Gloves and three MVP awards, and he was a feared hitter with a great glove.
Shortstop: Honus Wagner. Wagner is widely considered to be the greatest shortstop in baseball history, and he would be a great addition to any infield. He won eight Gold Gloves and was a feared hitter, and he was known for his incredible range and fielding ability.
Left Field: Ted Williams. Williams is one of the greatest hitters of all time, and he would be a great addition to any outfield. He won two MVP awards and two World Series championships, and he had a career batting average of .344 with 521 home runs.
Center Field: Willie Mays. Mays is widely considered to be the greatest all-around player in baseball history, and he would be a great addition to any outfield. He won 12 Gold Gloves and two MVP awards, and he was a feared hitter with a great glove.
Right Field: Babe Ruth. Ruth is widely considered to be the greatest baseball player of all time, and he would be a great addition to any outfield. He won seven World Series championships and four MVP awards, and he was a feared hitter with a great arm.
This team would be a powerhouse on both offense and defense, and they would be the favorites to win every game they played.
