About the Home Run Matt Holliday Hit Last Night
If, like me, you switched to Cardinals-Diamondbacks after the end of Yu Darvish’s almost-perfect game against the Astros on Tuesday night, you were immediately treated to the sight of something almost as interesting:
We’re about 0.8 percent of the way through the season, but that sixth-inning game-winner hit by Matt Holliday was one of the strangest home runs you’ll see this year. There are a few reasons why the pitch Holliday hit out of Chase Field was so unlikely to lead to a homer:
1. It was low. Really low.
The ball was 1.05 feet off the ground when it crossed the front of home plate. Only one pitch lower than that was hit for a home run last season, a slider 0.96 feet high (thrown to Delmon Young, naturally). And Matt Holliday is 6'4", so the pitch was lower relative to him than it would have been to most batters.
Since it came in low, it also went out low: the maximum height the homer reached, according to Hit Tracker, was 52 feet, which would have put it in the bottom 1.5 percent of home run heights in 2012. Also according to Hit Tracker, it would have been out of only five other parks.
*Update* Never mind the bit about it being a sinker. Here's what Cahill said:
I agree with the guys! Changeups are hit for home runs more often than sinkers, so that makes this a little less weird, but not by much. Only two lower pitches classified as changeups by PITCHf/x have been hit for home runs, one in 2011 and one in 2009.
3. It was thrown by Trevor Cahill.
So immediately after the excitement of Darvish’s domination, we saw a low-percentage homer hit off an extremely low pitch thrown by a pitcher who doesn’t give up fly balls. I don’t know if we learned anything, since we already knew that baseball is hard to predict and that Matt Holliday is strong and good at hitting home runs. But it was a helpful reminder that baseball never makes us wait long for the next nice surprise.
