Plenty of players have worn No. 15 throughout the long history of baseball, and with 2015 upon us, MLB.com takes a look at 20 Major Leaguers who have excelled while wearing the number.
Here are the 20 for '15:
Dick Allen: He spent 15 years in a Major League uniform and played for five organizations. The 1964 National League Rookie of the Year made seven All-Star teams and hit .292 in his career. Allen spent the bulk of his career, nine seasons, with the Phillies, and won the 1972 American League MVP Award as a member of the White Sox.

Sandy Alomar Jr.: Across 20 Major League seasons, Alomar played for seven organizations and wore as many numbers, but he did don the No. 15 as a member of both the Indians and Rangers. Alomar was a six-time All-Star, the 1990 AL Rookie of the Year and also won a Gold Glove Award in '90.

Carlos Beltran: Perhaps best remembered for his historic postseason in 2004, Beltran cracks this list having worn No. 15 for four teams -- Royals, Mets, Astros and Giants. In the '04 postseason, as a member of the Astros, Beltran hit .435 with eight homers in 12 games. Over the course of his 17-year career, Beltran has made eight All-Star teams.

Davey Lopes: A four-time All-Star, Lopes was drafted by the Dodgers in 1968 and spent the first 10 seasons of his 16-year career in Los Angeles. He led the NL in stolen bases in 1975 (77) and '76 (63), and now tries to pass that knowledge along as the Dodgers' first-base coach. He continues to wear No. 15.
Tim McCarver: A two-time All-Star and two-time World Series champion, McCarver accomplished a lot in his 21-year career. He played for the Cardinals, Phillies, Red Sox and Expos before starting his career as a broadcaster. McCarver's success carried on even after his playing days concluded as he won the 2012 Ford C. Frick Award for broadcasting.
Kevin Millar: He spent 12 seasons in the Majors and was a key component in the Red Sox 2004 World Series championship. Millar spent three years in Boston, five with the Marlins, three in Baltimore and one in Toronto. Millar hit .274 in his career and finished with 699 RBIs.

Thurman Munson: The Yankees are the only team to have retired No. 15, doing so for their former captain. During his 11 seasons in pinstripes, Munson was a seven-time All-Star. The catcher also won the 1970 AL Rookie of the Year Award and the '76 AL MVP. Munson tragically passed away in 1979 after he was involved in a plane crash.

Dustin Pedroia: If there's a baseball award you can think of, odds are Pedroia, 31, has won it. In nine seasons with the Red Sox, he has won a Rookie of the Year Award, four Gold Gloves, an AL MVP and a Silver Slugger. He is also a four-time All-Star and has won two World Series titles.

Tim Salmon: The 1993 AL Rookie of the Year is a rare example of a player who spent his entire career with one organization. The California Angels drafted Salmon in 1989, and he played 14 Major League seasons after his debut in 1992.

Ben Sheets: A four-time All-Star, Sheets spent nine of his 10 seasons wearing No. 15. Sheets spent the bulk of his career in Milwaukee, but also played with the Athletics and Braves. The right-hander finished his career with a 3.78 ERA.

Joe Torre: It's hard to find a baseball career longer or more complete than that of Torre. Not only did he play 18 seasons, but he managed for 29 years and also had a stint as a broadcaster. And if that wasn't enough, Torre currently serves as MLB's Chief Baseball Officer. During his playing career, Torre was a nine-time All-Star and won the 1971 NL MVP. As a manager, he won six AL pennants and four World Series championships. He was inducted into the Hall of Fame in 2014.
