AL yearly strikeout rate since 1954 with a runner on 3rd base and less than 2 outs compared to other cases

Yesterday I posted the same thing for the NL. 

I used Stathead to get this data. In the graph below the blue line shows the strikeout rate with a runner on 3rd base and less than 2 outs while the red line shows the strikeout rate in all other cases. Strikeout rate is SO/PA with IBBs and SHs taken out of PAs.

The two rates stayed pretty close to each other until the early 1980s (for the NL it was around 1990). For some reason, the rate with a runner on 3rd and less than 2 outs has been lower than for other cases since then.

This next graph shows the ratio of the runner on 3rd and less than 2 outs rate to the rate in other cases. As you can see, the ratio has been lower since around the early 1980s (for the NL it was around 1990).
