Eli in Connecticut read yesterday's post about the most innings pitched in a season and wrote:
I have a follow up question and am not sure how to find the answer. With the latest 15-inning win this past Friday (13-6), it made me wonder, "What is the largest run differential in an extra inning MLB game?" A home team, correct me if I'm wrong, can at maximum win by 4 runs, with a grand slam in the bottom of an extra inning. But away teams can pound away as we saw the other night! Any info is appreciated.
