The 10 Most Valuable Relief Pitchers of 2013
First of Two Pitching Lists

After ranking our Top 20 hitters of 2013 here and here, we’re back with two lists of pitchers.

Once again, this is just our “camera angle.”  We do not purport to have rendered all other baseball analysis obsolete, nor do we claim to “prove” that one player is better than another.  We are simply pointing out the interesting results that one gets when one examines the overlap of certain “non-random” results.

The philosophical background is here and here, and expounded upon here.

Relief pitchers are difficult to measure for a variety of reasons.  First, they don’t face a huge number of batters, so there isn’t as much data (some would call this “small sample size”; I don’t but that’s just me; I call it “small amount of data”).  Second, since the manager selects when they go into the game, they are more likely to pitch in situations that are favorable to their strengths.

So it’s not surprising that relief pitchers generally rank much higher than starters on our metrics, and these results don’t necessarily indicate that these pitchers would have the same level of success pitching as starters.

The minimum number of batters faced for ranking is 200.

SI reporting that the M's and Yankees had trade talks involving several players. Hmmmmmm? 'Kuma, I bet. Yanks also need 2B help as Drew is not good. Would they look at Ackley? Why not just give Refsnyder the fulltime gig? They could also use a 1B/DH bench typ bat. Montero....??? With his handful of hits last night (w/a 2B and HR), the kid is .465-.530-.775 over the last 28 days. Trade Ackley, DL LoMo, do something....but get Montero into our everyday lineup. Deej had two knocks in his Tacoma debut, btw.

Indubitably.

Imagine a future MLB park where the strike zone data is displayed on the jumbotron right next to the batter's picture and stats in real time, and where a sign is placed behind the plate and in two other spots on the outfield walls, and on the ribbon banners between the upper and lower decks on each side of the field that flashes red for strikes and green for balls the instant the pitch crosses the plate. Won't at bats be more fun to watch in that context?

2015-07-30 07:05

In short...it's only a matter of time. This is the best #News I've heard in my 25 years of watching baseball. I mean that.

2015-07-30 07:04

If the #Cali league is actually doing this and sticks with it for any length of time, two things will happen almost immediately:

1) The minor league statistics of batters and pitchers w/r/t plate discipline will get considerably more reliable (MLB teams will like this) because minor league umpires are known to be incompetent on a level far exceeding our MLB blue...and the MLB blue is pretty bad.

2) Minor league players who come from this league will begin demanding the automated strike zone in higher leagues as they advance. The players association will realize that the computerized zone is way better for their clients, and they will pressure MLB to adopt it.

2015-07-30 06:45

gnatto, yeah, bring it on.

2015-07-30 05:00

wowzers...couple of blockbusters last night...Hamels to the Rangers for six guys and Olivera to the Braves, prospects to the Marlins and Latos/Morse/Wood/Relievers to the Dodgers.

Also as for playing for draft pick.. start that up now.. Let us all face it.. no matter how close we may be to a spot, we are nowhere close. Not at all...Lloyd is not going to make it to the end of the year..,or should not.. start to shake up things sooner rather than later.

2015-07-29 19:39

Baseball team making me sick.. on to football chat yet..? football team not in total danger.. but after "passing" up anither ring.. off season has been filled with some negativity.. 2 d backs coming off injury..other 2 about to holdout. Star qb in middle of contract talk.. atleast they locked up Beastmode..but that got dicey. Hard to keep a champ together these days in the NFL or any league

2015-07-29 17:14

DJ going to Tacoma must mean Montero coming up to create room... so say hello to the DL Mr. LoMo

2015-07-29 16:19

When do we start playing for the high draft pick? Anyone worth hoping for?

2015-07-29 16:00

Good thing you aren't on twitter, DaddyO!!! People would be protesting at your house. I myself appreciate a good joke. I always thought the Confucius jokes were mocking the bad TV portrayal of the Chinese, so it's some deft comedy to turn it on the good ship mariner, which is a bad portrayal of a baseball team.

2015-07-29 15:31

Confucious say, man with egg on face not smile. Me say, How Li not smiling. Jack Z not smiling. Lloyd Mac not smiling. Confucious also say, sometime not sufficient wipe egg off face, face must be replaced. Confucious very wise man. (No offense intended; before PC correctness of the current era, when DaddyO was a kid, Confucious jokes were common, not to mock Confucious, but to use his reputed wisdom to, oh I guess, to mock someone else. Did I just admit to mocking Mariners' franchise leadership?)

2015-07-29 15:20

D-backs in process of completing the sweep. Clearly now the Mariners are dead #Men walking. Some SERIOUS shakeup in the offing, either soon or in the offseason. I find it difficult to imagine top brass doing nothing at all until the end of the season. This team has become a talented embarrass#Ment.

2015-07-29 14:44

Yeah. Where will his PT come from?

2015-07-29 14:34

Seems like an odd promotion. DJ has hardly been tearin' it up at #Jackson.

2015-07-29 11:33

Well that's something.

2015-07-29 10:05

@CurtoWorld: D.J. Peterson is joining the Rainiers today. Zach Shank sent to AA-#Jackson.

2015-07-29 08:00

Let's make room for Montero, huh? With his 3-4 last night (w/a 2B and ANOTHER 3B) he's .449-.519-.725 over his last 28 days, including the #Seattle stint. Morrison? .125-.222-.266 w/ a .104 BABIP. Trade #Jackson or DL Morrison (Hangnail?) or demote Ackley to #Everett, but do something! Heck, even trade Montero for something...at least that would be doing something. Well, don't trade him, really...but "C'mon #Dover! Move your bloomin' arse!" (for you My Fair Lady aficionados). And if we don't know now that 'Kuma will extend, then let's swap him out for something useful, too. Then resign him after the year.

2015-07-29 07:24

Mariners reacquire J.C. Ramirez. Remember him?

2015-07-28 23:06

Matt/Tacoma: I think the only team that gets away with weird platoons these days are the A's, and it's mostly because they have a super-fungible lineup with pronounced strengths/flaws. Like Matt said, it takes a fine touch and also the fact that a skill isn't linear and down to the resulting stats. If you played by the math #Book, you might miss out on a Walker-type power pitcher having a bad day, or the simple occurrence that a high FB pitcher might actually miss their intended target.

2015-07-28 22:57

So the Royals essentially go out and get Cueto, an awesome starter, and the best IF/OF backup in the league with Zobrist. Talk about taking things seriously!

2015-07-28 20:42

My anger management counselor says 70% of communication is body language. Ackley looks stressed/desperate.

2015-07-28 19:12

If we lose, It's your fault, browns

2015-07-28 18:23

Excited to see Iwakuna again as he continues to look good after getting back into the starting rotation. Hopefully I do not jinx him. Should be able to get a W tonight though

Works for me now. Please try it again. Glitches happen...

Matt... as much as the match ups for batters vs pitchers, I was wondering how much the umpire's strike zone comes into play in the decision... for instance Zunino can't hit the high fastball, but young umpire Davidson won't call a high strike on the fastball, so Zunino has a better chance to actually get on base then.

note to admins - something within the facebook plugin or something media6degrees.com - is forcing a reload of pages - which deletes in progress comments. Kind of annoying...
2015-07-28 12:48

Royals sure going for it

2015-07-28 11:43

Plus sabr and tacoma.., the other team is constantly adjusting too. You should always field your best 9, and with the good teams...those 9 do not change too often. Maybe some lineup changes..,but not overall in and out of games

2015-07-28 10:55

Tacoma...that would be absolutely correct if players were strat-o-matic cards. If you manage a team too heavily on match-ups, however, players tend to take that as a lack of confidence in them by you, the manager. E.g. if you find out that Zunino can't hit high fastballs anymore (he can't), and you bench him every time he has to fact a power pitcher with a high fastball affection, you're telling him "I don't believe you'll ever hit a high fastball".

2015-07-28 00:52

Matt - dumb question time... but first my assumptions.
1. teams track their own players strengths and weaknesses when batting
2. teams track and know what each opposing pitcher is good at - meaning tracking where each pitch is thrown effectively in a zone, like most pitchers have trouble throwing off speed stuff inside
3. each umpire is know to have a normal strike zone that they adhere to most of the time

Thus, if a manager is doing his job, he should be using these pieces of information to help pick which players should be playing each day... Correct???
Does anyone think Lloyd this?
