Reynolds -- rated the Mets' No. 7 prospect by MLB.com -- would be just the second player in the modern era to make his Major League debut in the postseason. Mark Kiger made two pinch-running appearances for Oakland in the 2006 American League Championship Series against Detroit.
A second-round Draft pick out of the University of Arkansas in 2012, Reynolds posted a .267/.319/.402 slash line, with six homers and 65 RBIs, in 115 games for Triple-A Las Vegas in the hitter-friendly Pacific Coast League this season. It represented a dropoff from the .333/.385/.479 line he recorded at the same level in 2014.
