ICYMI in Mets Land: David Peterson's struggles continue, Justin Verlander to throw live BP

Here's what happened in Mets Land on Saturday in case you missed it...

• David Peterson allowed seven earned runs, including four in the first inning, as the Mets fell to the San Francisco Giants 7-4.

• With the Mets already dealing with a very thin rotation, Peterson's ineffectiveness is becoming an issue for the club, writes John Harper.

• Buck Showalter said Justin Verlander will throw a live batting practice session on Sunday, while Carlos Carrasco will start throwing in two-to-three days.

• Saturday was another big day for some of the Mets top prospects, as both Mark Vientos and Ronny Mauricio had three-hit performances.

• Brandon Nimmo launched a home run, adding to what's been a stellar west coast trip for the center fielder.
