MLB chose not to institute a replay system whose sole goal was getting calls right, instead opting for a system that involved managerial challenges and strategy, at least until the seventh inning of games. In Tuesday’s Giants-Diamondbacks game, won by Arizona 5-4, we saw exactly what’s going to come of such a system.

Giants manager Bruce Bochy chose to challenge this call in the fourth inning. A.J. Pollock appeared to be picked off first base, but he was called safe on the slide.

The replay was deemed inconclusive, so the umpires will get to add this one to the “we were right all along” tally. Bochy lost his right to challenge, which proved big when, just a couple of pitches afterwards, Pollock scored from third on a passed ball.
