MLB Network's countdown of baseball's best players at each position concluded Saturday night with the last two installments of the "Top 10 Right Now!" series, featuring the game's top center fielders and relief pitchers.
The five-week program hosted by Brian Kenny -- which already ranked today's best right fielders, second basemen, third basemen, shortstops, left fielders, catchers, first basemen and starting pitchers -- used rankings based on player performance over the last two seasons, a number of offensive and defensive metrics, both advanced Statcast™ data and traditional numbers and analysis by the MLB Network research team.
The series featured appearances from MLB Network on-air personalities and former Major Leaguers Eric Byrnes, Cliff Floyd, Mike Lowell, Dan Plesac, Harold Reynolds, John Smoltz, Jim Thome, Dave Valle and Preston Wilson, as well as roundtable discussions with Kenny, president of SABR Vince Gennaro, the Ringer's Ben Lindbergh and MLB.com analyst Mike Petriello.
Each episode also featured a fan-generated Top 10 Right Now list compiled via voting on MLB Network's Facebook, Instagram and Twitter pages using #Top10RightNow.
Below is a breakdown of this year's rankings results:
