I'm not giving up on Valverde yet, but obviously he needs to removed as the closer until he works things out.
Eight runs in his past four appearances (two each inning); nine runs in his past five. Two blown saves in a row.
He tried a new set-position windup on Memorial Day, bringing his hands high over his head (like the oldtimers did). A new approach isn't going to work instantaneously. But you certainly don't experiment while other members of the bullpen have closing experience.
When a reliever is overpowering, he can groove an 0-2 pitch, hoping to blow it by the batter. When he's not doing well, you waste an 0-2 or 1-2 pitch, hoping the batter will chase it.
When I saw him challenge the batter with a fastball down the middle on an 0-2 count on Monday, I thought, the manager and his pitching coach are not doing their job.
