Dustin May
Will he maintain his start? No.
As painful as this may be to write, and as much as I hope it doesn't happen, Dustin May's Statcast data does not correlate with his actual performance at all so far. If his walk rate (9.3%, 44th percentile league-wide) remains the same throughout the season, it would rank as the second-worst mark of his career, while his strikeout rate (17.6%, 29th percentile league-wide) would be the worst mark of his career. And yet, despite those peripherals, May has given up just three earned runs across his three starts and 18.1 innings so far.
Those numbers just don't bode well for a successful season. His xERA is a modest 3.40, but to say he has overachieved given his peripheral numbers this season would be an understatement. May is going to need to have better command as the year goes on, while also missing more bats.
We know May has the stuff to do it, and with his velocity still sitting at 96+ MPH on both his four-seam fastball and sinker, he certainly has the potential to keep up this level. But, using the data we have available so far, the conclusion that May will maintain this level unfortunately seems unlikely.
