Sean Doolittle explains sabermetrics to you

22 Comments

Athletics reliever Sean Doolittle provides a nice service today. In filling in for Buster Olney at ESPN.com, he provides a nice primer to sabermetric concepts. Both educating uninitiated readers and putting lie to the notion that players themselves have no use for advanced metrics.

He even goes further, providing an inside view of some of the more esoteric, proprietary stats used by the Oakland A’s. For example:

BABIP: That’s batting average on balls in play, right? Wrong. It’s baseball averages compared to Bip Roberts. According to Baseball-Reference.com, over 12 seasons, Bip Roberts held a .294 batting average and a .358 on-base percentage and had a 162-game average of 36 stolen bases per year. Roberts played his final season for the A’s in 1998, but sabermetricians still use his stats when evaluating players.

Hmm. I’m starting to think only half of the column is to be taken seriously. Though, to be fair, his version of BABIP is more useful than some of the stats others use with a straight face.

Marlins trade David Phelps to the Mariners for four prospects

The Miami Marlins have sent reliever David Phelps to the Seattle Mariners in exchange for four prospects. MLB.com’s Mark Feinsand and Ken Rosenthal had rumors of the deal first, Jon Morosi, Jeff Passan and Jon Heyman (among others) all reported the trade at virtually the same time.

Phelps, 30, had a fantastic 2016 season, posting a 2.28 ERA in 64 games while striking out 11.8 batters per nine innings. He’s not been as strong this year, but he’s still been a solid setup man, posting a 3.45 ERA in 44 games while striking out 51 batters and walking 21 in 47 innings. He throws in the mid-90s and induces grounders. The Mariners could probably use rotation help more than bullpen help, but solid innings are solid innings at one point and improving your pen takes some of the pressure off of your rotation. Phelps will help Seattle with that. He’s under team control for next year too, so this is more than a rental.

The top prospect in the deal is Brayan Hernandez, a 19 year-old outfielder from Venezuela, currently playing in low-A ball. Also in the deal: righty Brandon Miller, righty Pablo Lopez and righty Lucas Schiraldi who, yes, is the son of ex-big leaguer Calvin Schiraldi. None of these guys are blue chippers, but you never know what’ll happen. It’s a volume return for the Fish.

We’ve already seen some big bullpen names move, including David Robertson, Sean Doolittle and Ryan Madson. Among others who could be moved:  A.J. Ramos (Marlins); Justin Wilson (Tigers); Addison Reed (Mets); Jerry Blevins (Mets); Brad Hand (Padres); Tony Watson (Pirates); Juan Nicasio (Pirates); Brad Brach (Orioles); Drew Storen (Reds); and Raisel Iglesias (Reds).

 

Corey Seager has more homers than any other shortstop in Los Angeles Dodgers history

Corey Sager homered in the Dodgers’ win over the White Sox last night. It was his 45th career homer, 44 of which have come while playing shortstop. While that’s great given that the guy has only played in 270 games, it’s not a lot of homers in an absolute sense. Thousands of players have more homers than that, obviously. Baseball has been around for a long time!

But it’s enough to set a record. A Los Angeles Dodgers record, specifically, for the most homers from a shortstop. It puts Seager past Rafael Furcal, who hit 43 while wearing Dodger blue. The record for the franchise, including Brooklyn, is Pee Wee Reese, who hit 122.

It seems astounding that no other Dodgers shortstop has hit more than 44 homers in the nearly 60 years since the club has been in Los Angeles, but it’s true. If you had asked me before I saw the factoid mentioned on Twitter I would’ve bet my life that Bill Russell would’ve had more. Not because he had any power — he was, in fact, one of the more punchless players of his era — but because he simply played in L.A. so long, logging 1,746 games at short for Walt Alston and Tommy Lasorda. Nope. He only hit 46 in his 18-year career, with a handful of those coming as an outfielder. His season high is seven. Seager has hit seven homers in May of his rookie season.

Oh well, you learn something new every day.
