Walking into the Mets clubhouse Friday afternoon, you’d never know the team was in the midst of the worst losing streak of the season.

New York Mets right-hander Kodai Senga, the major league ERA leader, was diagnosed with a Grade 1 strain of his right hamstring, hours after he was placed on the 15-day injured list.

However, it's hard not to call Kodai Senga an ace, given that his 1.47 ERA is the best in all of baseball right now. But in that case, it initially seemed like the Mets might be without their ace for some time after Senga suffered a hamstring strain while covering first base in the sixth inning of the Mets' June 12 game against the Washington Nationals.
