Bud Black’s second successful challenge on Sunday proved to be an especially crucial one. After already having a call at first base overturned in the seventh inning, Black challenged a ruling at first that Cameron Maybin had not beaten the throw on a slow grounder to open the ninth. The play was reversed and Maybin later scored the game-winning run as the Padres prevailed, 4-3, over Arizona in walk-off fashion to snap a four-game losing streak.
