Mets starting pitcher Steven Matz was supposed to start against the Arizona Diamondbacks at Chase Field on Thursday night. But now, thanks to a blister on his middle finger, he will start on Saturday, with Jason Vargas starting in his stead on Thursday.
Matz has bounced back after a rough April. Since the start of May, he’s posted a 2.68 ERA over seven starts, striking out 28. He has, however, walked 17 batters in that span and given up six home runs. He’s had a blister before, back in his rookie season in 2015, and it was also on his middle finger.
