MILWAUKEE - The Mets received a sliver of encouraging news Wednesday when second baseman Daniel Murphy began his minor- league rehab assignment.
Murphy, who has been sidelined with a quad injury, went 1-for-1 with a walk in a rookie- level Gulf Coast League game that was called in the fourth inning due to rain.
Now that Murphy has started his rehab assignment, manager Terry Collins said "it's probably three to four days" until his return from the disabled list.
Murphy is expected to resume playing third base, which he had been manning at the time of his injury.
Slumping rookie second baseman Dilson Herrera was given a night off to "gather his thoughts," Collins said.
Herrera is hitless in his last 14 at-bats. He's hitting .162 since June 10, when he returned to action from a broken finger that sent him to the disabled list.
Said Collins: "The fact that he spent two weeks on the DL and is coming back and playing at this level, I think as we all know it takes a little time to get used to the pace of the game and the quality of pitching you're seeing."
Already serving a suspension for PED use, Mets minor-league righthander Derrick Bernard, 23, received a 50-game sanction Wednesday, this time for testing positive for a drug of abuse.
Bernard's 50-game suspension will begin after the 62-game suspension that was handed down last August.
Bernard is on the roster of the rookie level Gulf Coast League Mets.
Catcher Johnny Monell started because Collins wanted another lefthanded hitter against Brewers righty Jimmy Nelson. Kevin Plawecki will start Thursday's series finale so he can catch Jacob deGrom . . . Michael Cuddyer was given a day off though he's expected back in the lineup Thursday.
