gregerson is getting a try out at closer at most, but he too doesnt have that K pitch.
Also, whoever is callin the pitches late in the game, is slacking. gregerson threw his big curve the 2nd pitch in back to back at bats. and then the next time he throws it low for a ball the hitters dont bite on it
Hes got a good fastball and a good changeup. hes got to work the count with those pitches, and then show the curve on a 2 strike count when the hitter is thinking about swinging the bat to stay alive. NOT the second pitch of an at bat.
