Who's next: 5 more players on the verge of retirement

Baseball has become a young man's game.

Twenty-three-year-old Bryce Harper became the youngest unanimous winner of the NL MVP on Thursday, just one day after newly minted 40-year-old David Ortiz declared, on his birthday, his plans to retire at the conclusion of the 2016 season.

While Ortiz has set forth his intentions, there are a number of other stars who are also approaching the final days of their careers. Here are five players on the verge of retirement:

Ichiro Suzuki, Marlins

Age: 42
Drafted/signed: 2001
Debut: April 2, 2001
MLB seasons: 15

Ichiro Suzuki has at least one more season left in the tank as he continues his quest to reach the 3,000-hit mark. The 42-year-old agreed to a one-year deal with the Marlins in October and sits 65 hits short of the goal. Suzuki recorded 91 hits across 398 at-bats last season, for a .229 average - the worst mark of his 15-year career.

Mark Buehrle, FA

Age: 36
Drafted/signed: 1998
Debut: July 16, 2000
MLB seasons: 16

While it was expected that the 2015 season would be his last, Mark Buehrle has yet to make a decision on his retirement. The left-hander had a strong year, but fell 1 1/3 innings short in his quest to become the fifth major leaguer to throw 200 or more innings in 15 consecutive seasons. Depending on his desire, Buehrle could likely find a deal after going 15-8 with a 3.81 ERA across 32 starts.

Chase Utley, FA

Age: 36
Drafted/signed: 2000
Debut: April 4, 2003
MLB seasons: 13

Chase Utley's agent says his client is 100 percent playing next season, despite coming off a year in which he provided career-worst production. The 36-year-old hit .212/.286/.343 with eight home runs and 64 strikeouts across 107 games, leading the Los Angeles Dodgers to decline his option and make him a free agent.

Bartolo Colon, FA

Age: 42
Drafted/signed: 1993
Debut: April 4, 1997
MLB seasons: 18

The oldest pitcher in the majors, Bartolo Colon continues to be remarkably durable as he approaches his 43rd birthday in May. The 18-year vet went 14-13 with a 4.16 ERA across 194 2/3 innings, the third straight year he's eclipsed the 190-inning mark. Colon has expressed interest in pitching next season, though where remains to be seen.

Carlos Beltran, Yankees

Age: 38
Drafted/signed: 1995
Debut: Sept. 14, 1998
MLB seasons: 18

Carlos Beltran's production in 2016 will have a direct impact on how much longer the 38-year-old remains in the league. Beltran's contract with the New York Yankees runs one more year, and the eight-time All-Star said last week that he might play another season if he's healthy and can produce. Beltran slashed .276/.337/.471 with 19 home runs and 34 doubles in 133 games last season.
