Unlike in years’ past, players who signed MLB contracts for the 2019 season cannot be traded after the July 31st deadline. Waiver trades no longer exist, so the only that MLB players can change hands after that is through the waiver claim process or by being released and signed to new free agent contracts. Those same rules do not extend to non 40-man roster players in the minor leagues, however, and today the Milwaukee Brewers announced a trade for just such a pitcher.
RHP J.P. Feyereisen (assigned to minor leagues) has been acquired from the Yankees in exchange for INF Brenny Escanio and international signing bonus pool money.
