Michael Conforto and Brandon Nimmo, born the same month, have played their entire MLB careers with the Mets, including six seasons as teammates in the Queens. Conforto, who did not play this year, has played 757 MLB games and Nimmo 608 games. Their career lines:
BN 608 G, .269/.385/.441/.827, OPS+ 130, 17.2 bWAR
MC 757 G, .255/.356/.468/.824, OPS+ 124, 15.7 bWAR
Nimmo has about four times as many plate appearances as Conforto has at the top of the order, but here are their career lines as leadoff hitters:
BN 1675 PA, .273/.380/.450/.829, tOPS+* 100
MC 414 PA, .258/.379/.504/.884, tOPS+* 114
Nimmo is projected to land a nine-figure contract while Conforto may need to settle for a one-year pillow contract. Of course, Conforto may be broken after undergoing shoulder surgery. Conforto's agent, Scott Boras, might tell teams otherwise.
* tOPS+ -- OPS for split relative to Player's Total OPS. Above 100 is good; below 100 is bad.
