BP Chats

2010-06-23 19:00:00 (link to chat)Would someone with Strasburg's stuff be A) Better, B) Worse, or C) the same if equipped with the brain of Brian Bannister?
(Ben L from NYC)
It's a real question - how much does thinking about what you're doing help a ballplayer? Moneyball spent a lot of time examining the question, and didn't really come to a good answer. I think it's rather scary to think of Strasburg getting better, though. (Colin Wyers)
2010-02-26 13:00:00 (link to chat)Is it just me, or are you getting tired of the "OMG, Joe Baseball Player doesn't understand advanced stats!!" meme. I mean, when did this become a mockable offense?
(marmour from Corvallis OR)
Joe Baseball Player doesn't have a whole to gain by understanding most advanced stats. All knowledge is good, but on the field? Not so much. Does Brian Bannister gain from some of what he's studied? Sure, but is something like his fly-ball-ground-ball rates "advanced ststs"? In today's day and age, they really aren't. (David Laurila)
2008-07-03 13:00:00 (link to chat)Thanks for the chat. I'm in a keeper league where the only pitching stats that count are innings pitched and runs (both earned and unearned) allowed. I'm thinking of trading Brian Bannister and Leo Nunez for Mike Mussina. Are my frustrations with Bannister leading to a bad move? Another wrinkle: whoever has Bannister would have control over him for the next few years, whoever has Mussina would be stuck with him next year as well, but I want to win this year. Thanks!
(Dennis from LA)
I think I'd do that. As much as I love Bannister's cerebral approach to the game and want to root for him, I don't want to touch him on any of my leagues. The blowup potential is just too high. Don't mistake that with an endorsement of Mussina - he's getting by now, but I think that dissipating strikeout rate is really scary. But ... he will get you those innings, and he's safer than Banny right now. (Jeff Erickson)
2008-05-01 13:00:00 (link to chat)Brian Bannister said after being pounded in Texas last night (paraphrasing): I'm a fly ball pitcher who pitches to contact in with the wind blowing out, I'm the last pitching in baseball we wanted on the mound tonight. His intelligence is well-known by now, but isn't it still refreshing for a major leaguer, in one quote, to reference park factors and accurately assess his own abilities and shortcomings?
(BL from Bozeman, MT)
That's a fantastic comment. It'll never catch on, but I love hearing baseball players talk about baseball, instead of interpersonal relations, or spouting cliches, or what have you. Maybe they don't all have much to say, but wouldn't you love to talk about hitting mechanics with Barry Bonds or Manny Ramirez, or pitch selection with Pedro Martinez, or footwork with Jeff Kent? There's a lot of baseball out there to be covered in the gaps between this controversy and the next one. We're working on it. (Joe Sheehan)
2008-04-23 13:00:00 (link to chat)Brian Bannister... I dont get it. Do you?
(Harold from Ithica)
I don't. And it bothers the hell out of me. (Kevin Goldstein)
2008-02-29 13:00:00 (link to chat)Dear Mr. Fox, Before my question, I must tell you that I have been a Cubs fan since my high school days in Niles, and I must say I really appreciate your blog piece on Goose Gossage. Now, about utilizing pitching f/x data: Your late piece on gyroball and Matsuzaka seems to bring light to the "deceit" of a pitch's movement. A surprising success of reliever Okajima last season had puzzled me. I tracked his pitching f/x data, and his pFx is weird. His pitches around upper 80mph moved WILDLY horizontally, ranging from a 10 to 15-inch apart from any trajectory line. I read mlbtraderumor's interview with Royal minor pitcher Brian Bannister. He talked about the sidespin of Jake Peavy's fastball that allows the pitch to move randomly and confuses batters. Is there any study on the effect of sidespin affecting batters' visualization of it? And had Okajima's pitches carry a similar, if not the same, effect of such pitches such as Peavy's or gyroball's?
(Dorasaga from Taipei, Taiwan)
Wow good question.

After I saw your question I went and pulled down Hideki Okajima's PITCHf/x data. I have 573 pitches for him which go into the post season.

In perusing his cannonical pfx chart he throws his three primary pitches (fastball, changeup, and curve) probably 90% of the time with his fastball ranging from 85 to 90, his changeup high 70s to 85, and his curveball from the low to mid 70s.

But in looking at the chart his fastball doesn't seem to move too much horizontally as compared to other pitchers. It sits in the 0 to 5 inch range whereas many pitchers see a tail of 5 to 8 inches on their fastballs. His changeup does tail 5 to 9 inches or so and drop about 5 inches more than his fastball.

What you may have seen is that his vertical component for the fastball registers in the 10 to 15 inch range but you have to remember that those values represent the difference from a pitch thrown with no spin. So in other words his fastball has a "rise" of 10 to 15 inches as compared to a theoretical reference pitch. In reality most pitchers see a range of 8 to 13 inchdes in this component and so his fastball may ride a little more than some others (which would be attributed to more backspin, not side spin) but it certainly doesn't tail any more.

Since you mentioned Jake Peavy I should mention that John Walsh at THT has done some great work on calculating the run value of individual pitches which you'll probably want to check out. But to directly answer your question I haven't seen anything specific on side spin or visualization of that. (Dan Fox)
2008-02-04 13:00:00 (link to chat)Thanks for your great work. Your interview with Brian Bannister was one of the best things I read all year last year. Just wanted to ask you your opinion on two players: James Shields and Nick Swisher. What do you see in their futures and who do you think is the more valuable player?
(Dennis from LA)
Thanks, Dennis. Bannister makes any interviewer look good.

I recently had someone opine to me concern about Shields' mechanics, specifically that they haven't been consistent over the course of his career. Granted, that's not my opinion -- I'm only passing along what I heard -- but if true it poses a question.

Swisher can hit. Given a choice of the two, I'd take Swisher. (David Laurila)

BP Roundtables

DateRoundtable NameComment
2010-04-05 09:30:00Season Opener Roundtable"redsoxin2004 (Columbia): Do you know of any teams, or individual players, that are using Pitch F/x or similar data in scouting and game preparation?"

Brian Bannister is probably the most prominent player using Pitch F/X and other sorts of data. There are several teams using Pitch F/X at least to some extent - most teams had reps in San Francisco for Sportvision's Pitch F/X Summit. (Colin Wyers)
2008-10-02 11:00:00Thursday Playoff GamesRandom fact #3: Dewayne Wise's home run today was his 16th in the big leagues. They have come off 15 different pitchers who have a combined record of 736-713; the winningest of the bunch being Jeff Weaver with 93. Wise homered off Brian Bannister twice this season. (David Laurila)
2008-09-29 10:30:00Tigers/White Sox Play-In GameGreg Pizzo (China, Maine) asks: "Does the terrific September by the Royals mean anything? Before the season started, we probably would have thought 75 wins was pretty good, but did they find out anything about their 2009 Royals using this September?"

I'm not so sure all that much progress was made. Guys like Billy Butler and Alex Gordon didn't take steps forward, they got a harsh reminder that Brian Bannister doesn't have a lot of upside, and even things that were good for them to have sorted out--like Tony Pena Jr. and Mark Teahen aren't regulars--didn't necessarily turn out perfectly well. It seems that guys like David DeJesus and Mike Aviles need to move from center and short, respectively. Their defense is a bit of a mess, there are questions over who plays where, and there's a mistake like the Jose Guillen contract to live down. On the plus side, Hillman seemed to get his bullpen sorted out well enough, Greinke's settling in, and Hochevar and Davies don't seem too far behind. They're still a few Gloads shy of having all the bricks to build a lasting foundation, but they're getting there. (Christina Kahrl)
