For all the positive things Luis Severino has done this season—further solidifying himself as a premier arm in the MLB with yet another All-Star nod—it is clear that the 24-year-old is in a major slump.

Call it a midseason hangover following the break or fatigue from carrying the New York Yankees weak rotation with an impressive AL-leading 14 wins, the young righty has lost his way recently. His latest performance on Saturday against the Kansas City Royals could be rock bottom. 

At least, Yankee fans hope this is the end of the downward spiral. Everything about the fall portends an underlying issue, however.

He gave up six earned runs in just 4.1 innings to one of the worst teams in baseball and certainly the worst offensive team in the MLB in terms of total runs scored. Unfortunately, New York's 10-5 loss provides insight to just how bad Severino has been in his last four appearances.

It's been a tale of two halves for Sev thus far, and the Yankees obviously can't afford to lose any more ground on the AL East-leading Boston Red Sox. Or, you know, let the Oakland A's keep charging at them from behind.

Sure, Gary Sanchez hitting sub-.200 and dealing with injuries is a serious problem. Yes, Gleyber Torres missing significant time has stung the club, and let's not even waste time discussing how detrimental slugger Aaron Judge's absence is for New York's powerful lineup. 

The reason why we have to put Severino under the microscope is because the team has enough depth to weather the storm of the issues mentioned above, so long as their ace comes to play. There's a chance something is significantly wrong with his now-flat stuff, and if the results are the current Real Severino, then Yankee fans have every right to be terrified.

The good news is that the Yankees have done a great job utilizing the trade market and adding valuable arms in starter J.A. Happ and reliever Zach Britton. New York might not even stop there after reports of a potential deal for Rays ace Chris Archer are picking up steam

Despite all of the help, Severino is undoubtedly the biggest anchor to this team. He sets the tone for the rest of the squad including the offense, bullpen and starters 2-5. 

If he can't get it right soon, then forget the division crown. The Pinstripes could be in an unexpected fight amongst the rest of the AL's hungry Wild Card-contending clubs. That's not something most expected just a few weeks ago, and it's too early to hit the panic button. Yet the pressure is slowly mounting.
