Looking at Walker's pitches, 92-93, 4 seamer, sweeper, slider, 2 seamer, almost no splitters.
A very expensive long reliever without that splitter working.
Allard was bad, couldn't throw a FB close to the K-zone (not that it's a great pitch at 90-91).
Without command, he has no chance, they're lucky they were only 4 down after 3.
