Hey, it worked for the Phillies and Blue Jays last season, so why won’t it solve all the Mets’ problems now?

One year ago, the underachieving Phillies fired Joe Girardi (22-29) and interim manager Rob Thomson (65-46) subsequently pressed all the right buttons on the way to a playoff berth and three series upsets to capture the National League pennant. On the other side of MLB, the middling Blue Jays fired Charlie Montoya (46-42) and turned to John Schneider (46-28), who piloted a return to the playoffs.

Now, a boisterous segment of Mets fans is convinced that firing Buck Showalter as soon as possible will provide the spark necessary to salvage a spiraling season.

Who can blame them when the $364 million World Series hopeful is now 6-16 in June (35-43 overall) — following Monday night’s 2-1 loss to the Brewers — and behind six teams for the final National League wild-card berth?
