Sonny Gray’s two most recent starts for the Athletics have altered his stock in a hurry, writes ESPN’s Buster Olney. Gray’s struggles over the past 13 to 14 months have been tied not only to injury but to a (quite possibly related) drop in his swinging-strike rate, but he’s racked up swings-and-misses in his each of his past two outings thanks to a revitalized breaking pitch. Gray’s velocity spiked in his most recent start, as well — an outing in which he completed seven one-run innings and whiffed 11 Marlins hitters on just 88 pitches.
