Mason: Dave Dombrowski says don't hold your breath on in-season extensions for Red Sox core

Jenrry Mejía, the first player in MLB history to receive a lifetime ban for PEDs, is reportedly Boston bound.

Mejía was reinstated for the 2019 season, and according to MLB Network's Jon Heyman, the Red Sox have signed him to a minor-league deal.

A right-hander, Mejia posted a 3.68 ERA with the Mets, but hasn't pitched since the 2015 season. The controversial reliever has been popped for anabolic steroids three times.

For what it's worth, he got off to a hot start in '15, allowing just six baserunners in 7 1/3 innings, but it's certainly fair to wonder how artificial those numbers are.
