Not all grand slams are created equal. The difference is in win probability added (WPA). In this series, Andrew Young’s grand slam had a WPA of 15%. Against the Padres on 28 Sept 2019, Christian Walker’s grand slam had a WPA of 57%. Nevertheless, all grand slams are appreciated!
Saturday’s two homers give the Diamondbacks 20 homers for the season. Their homers rank in a 3-way tie for third place in the Majors.
The last game of series with the Nationals starts at 10:05 am Arizona time. The game preview and game day thread can be found at AZ SnakePit.
