Starting Pitchers with Highest TTO%

We’ve talked a lot about Three True Outcomes for batters, most recently with Joey Gallo setting a new single-season record for highest TTO%.

Now lets take a look at the record-holders from the starting pitcher standpoint.  Here are the top 25 highest single-season TTO marks by starters with enough innings to qualify for the ERA title in that year.  As you would expect, the early years of Randy Johnson and Nolan Ryan dominate the list.  But the record-holder is the 1998 rookie season of star-crossed Kerry Wood. 47.5 percent of the batters he faced either homered, walked or struck out.

The D-backs’ Robbie Ray nearly topped Wood’s mark this season, with a final tally of 46.9%.  Max Scherzer and Chris Sale also made the top 25 all-time list based on performances this season.
