With the second month of the baseball season a mere 10 days away from being all said and done, many MLB managers are starting to feel the heat.
From teams with high expectations that are performing horribly to teams that have consistently struggled the last few years, some heads will roll before the season is over.
So, which managers are on the hot seat?
Don Mattingly is the most obvious manager on this endangered list.
The Los Angeles Dodgers have the highest payroll in baseball and are not even close to meeting expectations. While the Dodgers are dealing with a multitude of injuries, nobody expected the team to be seven games under .500 in May at 18-25.
Fox Sports' Ken Rosenthal believes Mattingly will get fired sooner rather than later.
If the Dodgers lose their current series with the Milwaukee Brewers, that move could happen during Thursday's off-day.
The last 14 months have been tough for the Philadelphia Phillies and manager Charlie Manuel.
Manuel had a dream team for a starting rotation in 2012, but the stars were out of alignment and things went wrong. This year hasn't been any better, as the Phillies are 21-24 heading into late May.
Making matters even worse for Manuel is that he is in the final year of his contract. Should the Phillies continue to struggle, the team may look elsewhere for a manager.
Unlike many of the other managers on this list, however, Manuel has at least earned the right to finish out the season.
Mike Redmond doesn't have much to coach with the Miami Marlins.
Fans know it. Even owner Jeffrey Loria knows it.
Apparently, Redmond's status with the Marlins came into question when Loria mandated Redmond make a change to the lineup during a doubleheader.
According to Yahoo! Sports' Jeff Passan:
Miami Marlins owner Jeffrey Loria personally mandated the lineup card change that flip-flopped starting pitchers Jose Fernandez and Ricky Nolasco in a doubleheader Tuesday and left Marlins players furious with his continued meddling, three sources with knowledge of the situation told Yahoo! Sports.
Loria has no respect for the game, as it's a general rule that veterans can pick which game of the doubleheader they want to pitch.
It seems Loria plays by his own rules, and he doesn't care how it may affect his players. He certainly doesn't care about Redmond. There's a good chance Loria will cast the manager aside after this year, claiming he didn't win enough games.
John Gibbons may be in his first year with the Toronto Blue Jays, but if the team doesn't at least finish above .500, his job will be in question.
The Blue Jays made big splashes in the offseason, acquiring R.A. Dickey and Jose Reyes, among others. They were favored by many people to win the AL East but have struggled this season.
Some may think it may not happen, especially considering GM Alex Anthopolous "went off the radar" to bring him back to Canada, according to Baseball Hot Corner.
However, if things continue to decline, look for a move to be made during the offseason, especially if there is a "sexier" managerial candidate available.
There are times when a team just needs a new voice in the locker room.
Mike Scioscia has done an excellent job of leading the Los Angeles Angels during the last 13 years. Despite helping make the Angels one of the class organizations in all of baseball, the team faltered at the end of last year and isn't doing so well this season either.
With a powerful lineup consisting of Mike Trout, Albert Pujols, Josh Hamilton and Mark Trumbo, it is surprising to see the Angels at 17-27.
Scioscia is a great manager, but maybe it is time for a new voice.
Terry Collins has been the manager of the New York Mets since 2011. In that time, the Mets have gone 168-198.
Should the Mets continue to struggle, Collins might not see 2014 as the Mets manager.
The Mets don't have a lot on their MLB roster, although Matt Harvey has given them a lot to be excited about.
Still, Harvey and David Wright aren't going to be enough to save Collins' job. The New York media won't allow that to happen.
