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.

rick82It does feel that way, but let's see what happens in the next two days. If we steal a game tomorrow, and Felix dominates, we may be feeling different.5 hours 52 min ago
Gordon GrossWe'll see. It's a bad week to have a bad week, but nobody's running away with the 2nd wildcard. We have offensive and pitching reinforcements. We'll see if and how we deploy them, but this is where a manager has to pull the right strings and get a lil lucky. We haven't been lucky the last week. Give it a minute to see if that continues.5 hours 53 min ago
SABR Mattwe are about to swoon out of the race IMHO6 hours 2 min ago
GLSLove to see the M's go after Hammel in the offseason.9 hours 11 min ago
DaddyOThe starting pitching seems to have hit a wall, and except for Ackley's resuscitating 3-run bomb in the final game vs. Washington this offense is again on life support. We are hanging in the Wild Card 2 chase only because our nearest competitors are also struggling. But we are letting more teams creep into the competition. Hope our current struggles are like they've been all year, temporary. What's worrisome is this is the first time the pitching has contributed to the struggles.9 hours 50 min ago

rick82Grand Slam Quintero should be activated immediately to put fear in the hearts of the Orcs!13 hours 47 min ago
moethedogThe Mariners have placed first baseman Jesus Montero on the suspended list for the remainder of the 2014 season, the team announced. The move comes as no surprise given that Mariners GM Jack Zduriencik recently said that Montero wouldn’t play again this year in order to focus on off-the-field issues. Montero’s suspension and Willie Bloomquist being moved to the 60-day DL creates two spots on the team’s 40-man roster that have been filled by catcher Humberto Quintero and right-hander Carson Smith, who had their contracts selected in corresponding moves.13 hours 51 min ago
rick82So nice to see our consolation prize draft pick salvage the weekend of Stasburg, Harper and Rendon.16 hours 16 min ago
MtGrizzly‬"I just think he's turned a corner," manager Lloyd McClendon said after Ackley finished 2-for-4 to lift his batting average to .260. "He believes in what he's doing and he's very confident in the type of player he is, and it's showing up in the field."‬1 day 7 hours ago
MtGrizzlyAckley is in a nice zone right now. He's very calm looking in the batter's box, which is nice to see.1 day 8 hours ago
DaddyOWhere would the M's be if the Ackley of July and August was the Ackley we've seen since his rookie year?1 day 8 hours ago
Tacoma RainOh now you have done it... Jinx city... Ackley is about to go zero for thousand1 day 10 hours ago
rick82Ackley is for real. I'm sold. And I didn't think Morales could get even slower. He's an albatross around this offense's neck with his inability to move. He needs more power to justify his spot in this lineup.1 day 11 hours ago
rick82I've taken my grandson to watch 18 innings this week, in which we scored a grand total of 1 run. The problem remains the offense. And last night...James Jones to the rescue? Where's Romero, the guy who's tearing apart AAA? Heck, Ty Kelly, for that matter.1 day 13 hours ago
Tacoma RainAdam Dunn to the A's for minor league relief pitcher.... I wonder how many more moves teams in the playoff hunt will make this year.1 day 15 hours ago
Tacoma RainMaybe our players are tired because of all the travelling and due to the stress of all the close games2 days 5 hours ago
IcebreakerXInteresting that the M's haven't been able to find a way to keep Felix & the starters fresh, even with the extremely awesome bullpen.2 days 7 hours ago
GLSWhy is our pitching staff getting worn down as opposed to other teams? Have our starters pitched more innings relative to the rest of the league?2 days 11 hours ago
MtGrizzlyFelix does tend to wear down in September. Troubling implications for October, should they get there.2 days 17 hours ago
