Mets Suspend Matt Harvey

4:22pm: It’s possible Harvey will file a grievance over the suspension, reports FanRag’s Jon Heyman. “This will end up in a grievance,” one source told Heyman. However, other sources Heyman spoke with indicated that Harvey’s unsure if he’ll contest the ban.

1:20pm: Harvey did not show up at Citi Field for the Mets’ game Saturday, per FOX Sports’ Ken Rosenthal, with a source telling him that Harvey had a migraine. The source also cited a potential miscommunication issue between Harvey and the Mets, but the club “evidently saw it differently,” writes Rosenthal (Twitter links).

12:47pm: Harvey’s suspension is the result of “a compilation of issues” going back to last season, report Seth Walder and Kristie Ackert of the New York Daily News. Prior to Saturday’s game, Mets owner Fred Wilpon and COO Jeff Wilpon engaged in a “heated” on-field conversation that was believed to be about Harvey, an industry source told Walder and Ackert.

9:40am: The Mets have suspended right-hander Matt Harvey three days without pay for a violation of club rules, reports Anthony DiComo of MLB.com (Twitter links here). The ban began Saturday and will run through Monday, meaning Harvey won’t make his scheduled start Sunday against the Marlins.

With Harvey temporarily unavailable, the Mets have selected the contract of Triple-A left-hander Adam Wilk, who will start against Miami. To create room for Wilk on the 40-man roster, the Mets have moved injured ace Noah Syndergaard from the 10-day disabled list to the 60-day DL, which had been expected to happen.

The Mets are unwilling to reveal the reason for Harvey’s brief suspension, per DiComo, with manager Terry Collins saying, “We’ll keep it in-house, the way it’s supposed to be.”

Sunday’s development continues a less-than-ideal year-plus for Harvey, who hasn’t resembled his previous top-of-the-rotation form since the beginning of last season. Harvey logged a 4.86 ERA over 92 2/3 innings in 2016, and then underwent season-ending thoracic outlet syndrome surgery in July. In his return this season, the 28-year-old has continued to throw hard, yet his once-high strikeout rate has dropped to 5.14 per nine innings and he has posted a career-worst walk rate (3.34 per nine) over 35 frames. Thanks in part to his declining K/BB ratio and swinging-strike percentage (7.4, down from 11.7 from 2012-16), not to mention a sky-high home run-to-fly ball ratio (21.2 percent), Harvey’s ERA sits at a lofty 5.14 through six starts.

As of now, the only Mets starter who has gone through 2017 without any real issues is Jacob deGrom. Syndergaard, Steven Matz and Seth Lugo are all shelved with injuries, while Robert Gsellman and Zack Wheeler haven’t been as effective as they were previously (though it’s understandable in Wheeler’s case, as he’s returning from Tommy John surgery).
