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.

DaddyOSome of the MLB coverage is delayed, but ROOT Sports is broadcasting live Wed/Thu of next week, and then three weekday games the following week.10 hours 36 min ago
okdanShannon Drayer has some cool video up of Patrick Kivlehan, Jordy Lara, and D.J. Peterson taking BP down in Peoria. Just BP of course, but my initial reactions are: Kivlehan looks athletic but a little jumpy at the plate. Lara looks like he could be a beast, big kid. DJ looks patient and cool as a cucumber, like a 10 year vet in the box.

SABR MattCorrect...MLB.TV's spring schedule shows us getting coverage on the 4th, 5th, 6th, 9th, 11th, 13th, 15th, 18th, 20th, 22nd etc...regional sports network new deal must have included expanded ST coverage. Usually we don't get anything until the 15th or so and then only 6 games all spring.11 hours 5 min ago
DaddyOIIRC, usually it's not 'til the middle of spring training that we begin to see TV broadcasts.11 hours 7 min ago
DaddyOOn the M's official website here: http://seattle.mariners.mlb.com/schedule/broadcast/index.jsp?c_id=sea11 hours 8 min ago
SABR MattWhere did you see that?11 hours 31 min ago
DaddyOAm I seeing this right? The M's are starting to televise spring games right away, starting with next Wednesday and Thursdays games games against the Padres.13 hours 29 min ago
SABR MattMoe...SS is a weakness until someone actually does produce. Neither Miller nor Taylor has proven anything15 hours 23 min ago
MtGrizzlyAssuming Weeks can play LF, the bench puts a pretty decent floor on the current roster. The platoon advantages can help cover for under performance a bit. It's curious - individually, I don't really llike Weeks, Bloomquist or Ruggiano but as an ensemble, I think they kind of work.1 day 55 min ago
moethedogNo weakness at SS. One of those guys will produce.1 day 1 hour ago
SABR MattSo I see the Mariner offense as having three major ?s SS, LF and 1B. I don't much care for Zunino's chances of being awesome in 2015 either but we don't need him to kill it to be a hero. We need better than we got from SS in 2014 and we definitely need production in LF and at 1B. But of those questionmarks, we have solid possible replacements lined up at 1B (Montero, Peterson, Kivlehan) and SS (Taylor, Marte)...where we are weakest is LF (Kivlehan, Romero)...but there are a lot of teams who would enjoy that sort of weakness in depth.1 day 8 hours ago
moethedogDead on Matt. Just posted that I absolutely expect one of the Montero/Kivlehan/Deej/Romero quartet to mash there way into the lineup. Which one? Don't know. But those 4 rolls of the dice are more likely to be a natural than the one roll of LoMo (or Ackley). BTW, if one of you guys has a voodoo doll, could you get a little mojo going for a Bloomquist hammy pull?1 day 10 hours ago
SABR MattMoneyball thought - did the Mariners intentionally leave 1B open because it's pretty easy (theoretically) to work a prospect or platoon bat in there when he's hitting enough to merit the call? The media is talking about how big of a gamble it is for Seattle to count on Logan Morrison. I see five guys queued up in line behind him with a legit chance to be productive: Montero, Weeks, Kivlehan, Peterson, Romero.1 day 11 hours ago
benihanaI'm with you Matt. I kind of want the M's to trade Taylor, Lomo, and Ramirez for Fielder and some $$. What a murderer's row would Cano, Cruz, Fielder, and Seager make?2 days 4 hours ago
DaddyORight re: underground drip irrigation. That's what I was referring to. If you are spending $125 million on ballplayers every year you would think it would be worth it to protect that investment even if it costs a million dollars a year. I dunno, maybe I'm wrong here.2 days 4 hours ago
SABR MattFWIW, I bet 37 roto dollars on Prince Fielder this year. I think he will have a good year2 days 5 hours ago
mojicianHamilton would have been the biggest bust in the history of Seattle. They would have run the entire Z regime out on a rail for 2014 Hamilton performance alone. It says here if you are going to have a star, he should have great makeup. I think Fielder will bounce back. His game wasn't dependent on being a yoga instructor. What he has are large muscles and a disciplined plate approach, see Papi, Big. Fat guys rake.2 days 6 hours ago
SpectatorAnd how about Z whiffing on Hamilton and Prince Fielder before connecting on Cano, the only one who looks to hold his superstar value? Balance of power in the West could turn on those three contracts.2 days 7 hours ago
SABR MattYep...Taylor would probably go to AAA so that Lloyd could have his cheerleader on the bench not begging for PT and Taylor could work on his plate discipline.2 days 7 hours ago
SpectatorLloyd says if Bloomie healthy, then Miller and Taylor won't both make roster. At least that's their plan at the moment.2 days 7 hours ago
