I hadn't, but it's a good question, and unfortunately there's an illuminating answer available at baseball-reference.com https://www.baseball-reference.com/leagues/split.cgi?t=b&lg=MLB&year=2019#all_innng MLB-wide, extra inning OPS isn't too out of line with other innings. (The 9th is markedly low, and there are probably good reasons for that, going beyond the word "closer".) https://www.baseball-reference.com/teams/split.cgi?t=b&team=MIN&year=2019#all_innng Our 2019 Twins have an extra inning OPS of .602, going into today's game. The ninth inning isn't aces either, at .683. I needn't tell you, this is lower than any other inning. It's small sample size territory (106 PA in extras), but not comforting. We go from above average offense to below average, after eight. Time for some soul searching for our batters, and probably the batting coach as well.
