NEW YORK — The news keeps getting worse for the New York Mets.In their 5-2 loss to the New York Yankees on Friday, starter Clay Holmes suffered a fracture in his right fibula that will keep him out “a long time,” manager Carlos Mendoza said.Holmes was hit in the right leg by Spencer Jones’ 111 mph low line drive in the fourth inning. The ball ricocheted into foul territory, allowing Jones to reach first base. Remarkably, Holmes stayed in the game not only to finish the fourth inning but also to get another out in the fifth.Only when he walked Jazz Chisholm Jr. and came out of the game did Holmes feel as if something was wrong in his leg. An X-ray confirmed a fracture.“It’s a huge blow,” Mendoza said. “He’s been one of the most consistent guys we’ve had in our rotation. Yeah, it’s a really big blow.”“It just sucks,” Juan Soto said. “Clay is one of the hardest workers I’ve seen in my career. It’s really sad when it happens to him.”“It says a lot about who he is to go back out there again that next inning with a broken leg,” Jones, who has worked out with Holmes in the offseason in Nashville, Tenn., said. “It’s incredible.”The injury to Holmes is a blow for so many reasons. First, he’s been the Mets’ best starting pitcher this season. He entered Friday with a 1.86 ERA, and New York was 5-3 in his starts (compared with 13-22 in everyone else’s). The four runs he allowed in 4 1/3 innings to his former team Friday were his most in a start this season.
