New York Yankees fans pulled no punches following Saturday night's 1-0 loss to the St. Louis Cardinals.To add insult to injury, the shutout came at the hands of the very pitcher they shipped off at the deadline, Jordan Montgomery. He threw five shutout innings. He surrendered only two hits on the night and registered the win.Fan frustration is understandable in the wake of the trade deadline. After a flurry of moves that saw Andrew Benintendi, Lou Trevino, and Frankie Montas join the pinstripes, the New York Yankees have yet to win.Snake@Elijah_ShrinerFire Brian Cashman and fire Aaron Boone.

Nobody envies the scrutiny you're subjected to if you fail to perform to the standard. Just ask Joey Gallo.New York Post Sports@nypostsportsJoey Gallo felt like 'piece of s–t' before Yankees traded him trib.al/DfHgp5121Joey Gallo felt like 'piece of s–t' before Yankees traded him trib.al/DfHgp51 https://t.co/ZyNWMptkEFNot everybody can handle the pressure of donning pinstripes. The question is, can this version of the New York Yankees thrive under pressure, or will they cave beneath the weight of criticism?Are the New York Yankees' recent struggles cause for concern?Manager Aaron Boone of the New York Yankees visits the mound.With the trade deadline so fresh in the rearview mirror, it's easy to scrutinize the Yanks' four-game losing streak. However, it's not time to panic just yet. Despite their losing streak, the Yankees still sport the best record in the American League.Every team hits a few bumps on the road. It's better to get those kinks out at this point in the season. This would be a disaster if it were happening during the final games heading into the playoffs.Ironically, pitching has been the issue of late with the Yankees. They have surrendered a total of 20 runs in their past four outings. That 5.00 ERA includes Saturday's 1-0 loss.Aside from the shutout, offense has not been the issue for the Bronx Bombers. They may have whiffed in their recent contest, but their 12 runs in the three games prior to Saturday is less worrisome than their pitching woes. Considering these struggles are uncharacteristic of the club that holds the third-lowest team ERA at 3.24, expect the rotation and bats to rebound.
