Atlanta Braves fans want a closer: Here’s data to help you pick one
By Fred Owens
Clean innings and meltdown innings
Noting irks fans more than a reliever that immediately puts runners on base, particularly in a save situation. Fangraphs provides a metric for shutdown and meltdown innings; a complex calculation designed to replace the save.
". . .(the metrics) answer a simple question: did a relief pitcher help or hinder his team’s chances of winning a game? If they improved their team’s chances of winning by a certain amount, they get a Shutdown. If they (made it worse) certain amount, they get a Meltdown."
That’s all very nice, but I wanted something simpler.
Last year I introduced my no-hit innings pitched statistic. Unlike SD/MD I look for the number of innings a pitcher didn’t allow a hit or walk more than one batter, then set it as a percentage of innings pitched.
For those who did complex stats, the table below shows the Fangraphs SD/MD as a percentage of their relief innings as well as my NHIP metric. All of the pitchers included pitched a similar number of innings.
All statistics derived from or come directly from Fangraphs.
Player ID | NHIP/IP | MD/IP | SD/IP | Notes |
9073 | 49% | 7.0% | 69.8% | |
10756 | 53% | 11.1% | 58.3% | |
12076 | 34% | 7.1% | 52.0% | Allows base runners but usually gets out of trouble |
6661 | 65% | 5.2% | 49.1% | |
9111 | 57% | 7.2% | 57.6% | |
8048 | 57% | 7.1% | 68.6% | |
11710 | 46% | 6.1% | 51.0% | |
7196 | 55% | 15.2% | 48.5% | Solid but can let things get out of hand |
6986 | 44% | 17.4% | 29.8% | |
12910 | 42% | 6.1% | 45.5% | |
10430 | 44% | 18.3% | 33.9% | |
11682 | 34% | 15.9% | 35.7% |
I added a couple of hot takes on the data. FG looks as every inning so the percentages won’t match, but when they are close, it’s a good thing.
For comparison’s sake, Luke Jackson has had one clean inning in eight July outings. He’s had 12 clean innings in 45 appearances this year, so in 26 percent of his outings this year he hasn’t allowed a hit or a walk.
But if you use my NHIP/IP method he has 14 such outings, which is good for 31 percent.
