A very late post tonight but I had an all day meeting and this is more than substantial enough to warrant it. Much was made about Lance Lynn’s second half surge. He had struggled with command early in the season and frankly just was underwhelming. As the season progressed, however, he achieved some impressive results including a 16 strikeout game.
With the release of the Baseball America and Baseball Prospectus lists came some unusual — and the first I’d heard mention of anywhere — reports that Lynn had gained some velocity on his fastball. John Vuch, Director of Minor League Operations, was kind enough to fill me in on some of the details of Lynn’s improved fastball. Mr. Vuch noted that Lynn had some minor nagging injuries earlier in the season and went on to say:
He did touch 96 on several fastballs late in the year, but really worked more consistently in the 92 MPH range (with quite a few 94’s). Since earlier in the year he would sit at 90 MPH with the occasional 92-93, the gain in velocity is significant, at least in terms of where he finished the season. Much of Lynn’s success stems from the deception in his delivery, which allows his fastball to “jump” out of his hand, making his fastball a swing and miss pitch.
Without seeing Lynn’s new fastball, I can’t speak to the deception but 2 mph on average is a very significant velocity gain. I’m not sure that it radically alters the “consensus” view of Lynn as a middle of the rotation type player but it certainly grates against my personal opinion based on the time I saw him in person and the video of Lynn I’ve watched.
I also asked Mr. Vuch what might the ideal version of Lance Lynn fully developed would be like.
Ideally, Lynn can pick up where he left off at the end of last season, and continue to improve his command of all pitches while maintaining his velocity. A big key for him is to continue to have a consistent delivery, which helps him to reduce his “mistake pitches” (which led to the majority of his mid-season HR problems). When his command is on and he makes his pitches and hits his spots, he’s very effective, so it’s really a matter of consistently executing his pitches.
There’s a bit of a coy response there since any pitcher that consistently executes their pitches is going to see the best results there. I think Mr. Vuch is speaking to a general point that we can talk about control and command of pitches in an isolated sense but those things are very closely tied to good repeatable mechanics. Specifically for Lynn and the long held Cardinals organizational philosophy about pitching low in the zone, command is a factor in his effectiveness to avoid the homerun.
It’s worth keeping in mind that Lynn did have a mixed 2010 but I hope this helps shed some light on (some) of the reasons for that. I’d feel irresponsible to tell you to totally disregard his first half performance — indeed, Lynn will probably have times when he loses his mechanics for a couple starts and has command issues — but Mr. Vuch’s words certainly lend credence to the arguments that Lynn’s second half was more characteristic of his ability than the first half of 2010.
It’s easy to focus on what we as fans have considered organizational “failures” in the past with regards to certain prospects. For those of you keeping score, this looks like a clear point for the organizational “successes” column.

Lynn’s 2nd half was nice to see after an uneven first half of the season for him. Like you, still see him as more of mid rotation starter than top of the rotation type, but with that said, mid rotation starters still hold plenty of value to any team, and its nice to have a Lynn type pitcher close to the major leagues. Its also a nice luxury to be able to have him continue to work on things in Memphis but also glad to have him as a decent fall back option should one of our 5 starters get hurt, which seems like a good probability over the course of a 162 game season and the injury history of them.
For a guy who convinced me that FIP was a good measure of a pitcher I’m surprised and disappointing you didn’t challenge Vuch on whether, based on FIP, Lynn’s second half was really an improvement (there was minimal difference by my rough calculation). Not only would it be interesting in general terms to hear his response, we might have gotten some very useful insight into the importance (or not) of FIP to the Cardinals in terms of evaluating their minor league prospects.
GREAT stuff, AZ; thanks for sharing it.
I’m not John Vuch, but here’s how I’d have answered CC’s point if I was. “Good question, but keep in mind that FIP, like all tools like it, is prone to small-sample-size effects and selection bias. Velocity on a fastball is not. You don’t need three seasons’ worth of radar-gun statistics to notice it when a guy gains 2 mph on a fastball; two or three games before the gain, and a similar number afterward, will tell you whether the gain has occurred. That, for me, says more about Lance Lynn getting on track than FIP or mid-season splits can. Thanks for calling.”
“Yes John, but velocity isn’t worth much if a player cant locate the pitch or fool anyone. From his FIP (small sample size or not) it doesn’t appear he did any better (or worse) in doing that in the second half than he did the first. ”
In all fairness to Mr. Vuch. I’m not sure he actually said that Lynn’s 2nd half was an improvement. It was Az that indirectly indicated his 2nd half was better.
Lynn’s FIP may be equivalent between the first half and second half of the season but for entirely different reasons. In the first half, his command was weak and he didn’t have an effective fastball. In the second half, he got bit by the long ball. If you normalize for HR rate, his second half was better though not substantially so.
The goal of the post wasn’t to make a comprehensive argument about Lynn’s season. It was to share with you guys a report about his velocity. Read the article with the narrow focus it was intended in.
I was able to see Lynn pitch from behind home plate in his first year at springfield. His fastball then sat 88-92. I left the game thinking jeff suppan (in his prime for the cards) was a good comp. for him.
That answers my question which was whether the 2MPH gain was added just over his first half of 2010 or whether that’s a gain over his historic base line. If he’d just lost a couple of MPH and then regained it it wouldn’t mean much but it sounds like it’s territory he hasn’t been in before. If he maintains it he might have a higher ceiling than we thought.
I believe he was up in this range his So year in college and lost velocity in his Jr year.
great to hear of improved velocity. In Lynn’s case, though, isn’t it possible that an improvement in mechanics and control would be directly related, or COULD be directlly related to his conditioning? I know pitchers in the past have pitched well with less than svelt physique’s. in most cases, though, wouldn’t you think that losing weight, while maintaining strength and flexibility, would lead to better repeatability of his motion AND a possible increase in velocity? haven’t seen him personally, from what I have read he is not an athelitic specimen. just wanted others opinion on this, maybe he just got into better shape later in the year, does anyone have info on this? thanks.
His increase in velocity is significant is that it eventually helps him become a better major league pitcher.
