On Saturday, Diaz made his first major league start. He has a bit of an odd, stiff delivery, but the ball explodes out of his hand. He struck out the second batter of the game, Jorge Bonifacio , on three swinging strikes -- all fastballs, 98 mph, 98 mph, 99 mph. He hit 100 a handful of times. He got in one jam, then got Mike Moustakas to ground into a rally-killing double play. He fell behind Eric Hosmer 3-1, then got Hosmer to pop out into foul territory. He went two innings and didn't allow a run. This isn't just not you signing with the Padres; this is credible. The 3,000th-best baseball players in the world are credible.
