Matt Harvey’s mystery ailment finally has been revealed.
The Mets’ ace had a bladder infection that prompted blood clots, he told reporters Tuesday.
Harvey said he was tested Monday and cleared for light activities.
The club shut down Harvey for the rest of spring training on Monday, but Harvey said he’ll be able to make his Opening Day start on Sunday night in Kansas City. Harvey said he may throw a couple of innings on Wednesday to prepare for the start.
