St. Louis had 5 LHP in that series, and 3 of them started 5 of 7 games (Tudor 2, Magrane 2 and Mathews 1). LHP threw 29.2 IP, RHP threw 29.1 IP.
Hrbek faced a LHP in 17 of 29 PA in that WS; 2-16 (.125), 3/1 K/BB (his only 3 K's in the WS) 1 HR, 6 RBI, but came up big when needed. He was 3-8 (.375), 0/4 K/BB (.583 OBP), 0 HR, 0 RBI against RHP
Larkin PH 4 times, each of the 3 games in STL as the pitchers still hit in the NL park at that time, and once for Randy Bush (F-8 against Dayley in game 2, an 8-4 Twins win. If the game was closer I think Baylor, not Larkin, hits for Bush). He also played 1B in the 9th inning of game 1, a 10-1 blow out victory for the Twins. so his totals were; 5 GP, 0-3, 0/1 K/BB in the series.
Even with all this information, it is hard to tell if Rocco PH's for Hrbek against Dayley in that spot, I don't think so because Hrbek was one of the core players, but he was struggling and the team was on the verge of elimination. Thank goodness TK let him hit!!
