A couple of days ago, before LoMo made his hopes come true, Colin O'Keefe tweeted this out:

Since 2010, the Mariners have 60 walk-off loses and 20 walk-off wins. Here's to hoping they can close the gap to 39 tonight.

As Colin was tweeting I was poking around walkoff data in bbref myself. Here's a little deeper dive into the walkoff stats over the last 15 years. First here's walkoff wins and losses by team this millenium. See if you can find the Mariners (I'll give you a hint, they are at the bottom).

Wow, that's pretty bad. What pitchers were responsible for all those walkoff losses? Here's some of your leaders.

Of course those numbers are not scaled for number of opportunities to give up a walkoff hit. In any case I do find it a bit sad that Dominic Leone has had the opportunity to give up 3 walkoffs in his short career. Seems unfair to put him those high leverage situations. But if we can't blame the pitchers, who can we blame?

Well, here's a little chart that shows the evolution of each team's net walkoff number starting in Y2K. Each time they win in a walkoff their line ticks up, each time they lose it ticks down. See if you can figure out who I blame.

The M's actually won more walkoffs than they lost in 2009, but since then, as Colin pointed out, it's been a disaster. Almost all of the teams are bunched between -20 and +20 except for Seattle and Oakland. Almost makes you think GMs matter.

OK that's the bad news, but we won a few walkoffs as well. Let's take a look at good news - who are the batters that got the walkoff hits for us?

That was a surprise. Jose Lopez and Yuni at the top of the list? Yup:

Wonder why I don't remember this gem from 2006: Yuni hits a single, Bloomquist scores, Reed to 2nd. It's like the replacement-level all stars. All I can say is that if your good news arrives in the form of Yuniesky Betancourt and Jose Lopez, there isn't really any good news.
