Launch it Higher!


Dear Frank,
 
After reading your book and your column regularly and loving your very insightful explanations I just couldn't hold back my questions.
 
How does altitude affect the optimum launch conditions for a driver? Let me explain my situation. I live and play golf here in Ecuador at an altitude of 9000 feet, so the aerodynamic conditions are completely different than at sea level. From what I can deduce: due to the lower lift and drag properties of the thin air a driver would have to generate more spin and have a higher launch angle to achieve optimum conditions but I was wondering if you can shed some light into the matter.
 
And a following more specific question: As Ecuador is not known for its abundance in golf stores, let alone launch monitors I wanted to take advantage of a future trip to the U.S. to test out some new clubs and I wondered: How should I choose a driver loft for 9000 feet once I have found my optimal value at sea level?
 
And as all good things come in three: Can you please recommend a loft/shaft stiffness to start testing for me (Have those 9000 feet in mind). Swing speed is 90 to 100mph, at the moment I play with 9.5 (I know now it's low, but two golf pros suggested it) stiff shaft driver. I hit 200 to 230 yards with a fairly low trajectory and relatively lots of roll (if I hit the fairway).
 
Thank you for your time and keep up the good work,
-Michael

 
Michael,
 
You are correct. Due to the lower density of the air at an altitude of 9,000 feet, the ball needs to spin a little more and be launched a lot higher compared to sea level to give you maximum distance (optimum launch conditions).
 
At 100 mph head-speed you will gain about 40 yards in total distance at 9,000 ft compared to sea level, if you launch the ball at about 16 to 17 degrees compared to 13 degrees at sea level. A spin rate of 3000 rpm is good and for your head speed get a driver with a stiff shaft and loft of about 15 degrees (which is about the max. available).
 
You should understand this assumes the temperature remains the same. Unfortunately, as you increase in altitude you decrease in temperature, which will have a detrimental effect on distance because the air is more dense at colder temperatures but not enough to be of major concern. Just keep your body warm and hit it high in warm humid weather at altitude (9,000 ft) and you will gain about 35 yards over your 240 yards at sea level drives.
 
Just a reminder when the air becomes humid, at any altitude, it will be less dense because water vapor molecules made up of hydrogen and oxygen have a lower molecular weight than nitrogen and oxygen molecules, which they are replacing. Nitrogen and oxygen make up about 90% of the air we breathe so replacing these with lower weight molecules will make the air less dense.
 
Humid air is therefore lighter, not heavier and this results in less lift on the ball but also less drag. So on high humidity days launch the ball a little higher.

Special Balls for Putters


Hi Frank,
 
First let me say that I am a new owner of a Frankly Frog putter! I have used both blade and mallet style putters in the past [most recently using a ' TMMC (full name redacted) putter] and am your stereotypical 'feel' putter. I have avoided sight lines and the like on a putter for a very long time. However, after reading some of the testimonials on your site, I thought I would take a chance and, wow, am I pleased! I am consistently hitting my putts along the line that I want (although I still need some green-reading prowess!!) and my distance control is good on putts of any length. In addition, my pulls and pushes seem to be reduced...new club'itis? Perhaps, but my confidence on the green has increased many-fold thanks to the frog.
 
Now my question.....
 
Based on today's designs, is there an optimum ball for the Frog (or for any style putter)? Meaning, based on the materials used and machined faced qualities, is there a particular type of ball that would get the most out of the design? Hard cover? Soft Cover? Three piece? Two piece?...etc.
 
Thank you for sharing your ideas and your technology!
 
Best Regards,
-Kevin

 
Kevin,
 
Thank you for the kind comments about the Frog Putter. You can request a download of a free putting guide by clicking here and make sure you take advantage of the putting tips provided. This will really keep you on track; give you something to practice and enhance your success and confidence on the green.
 
With regard to a special or optimum ball to be used with the Frog, please remember that you are not permitted to change balls during the play of a hole unless it is so damaged as to be declared unfit for play. With this in mind select the ball type you feel most comfortable using tee to green and make sure you use this ball type during your putting practice.
 
There was no specific ball which I had in mind when designing the Frog.
A suggestion which will help your putting, is when you get onto the practice putting green to calibrate your stroke before a round during your warm up - this is not practice but getting a feel for the green speed and building confidence - take only one ball onto the practice green. Read each putt using your pre-shot routine and hole it out every time - no matter how short the putt may be. This will remind you to follow a plan and stick to your pre-shot routine when you are on the green during your round.
 
Kevin, becoming a good putter takes a little work but by following good instruction to improve, will help the rest of your game because you build more confidence on the green and carry this to the next tee. Of course, it also helps to have a good putter.
 
I am pleased you have discovered how well a good putter works.
 
-Frank

Fleetwood flawless en route to Abu Dhabi lead

By Will GrayJanuary 18, 2018, 2:06 pm

New year, same results for Tommy Fleetwood.

The reigning Race to Dubai champ picked up where he left off in the opening round of the Abu Dhabi HSBC Championship, carding a bogey-free 66 during which the Englishman found all 18 greens in regulation. At 6 under, he shares the lead with Japan's Hideto Tanihara and sits one shot clear of five other players.

"Very stress-free. Played really well from start to finish," Fleetwood said. "Felt like I did what you need to do around this golf course, which is drive it well, hit your irons solid. You can't really be too greedy a lot of the time, and then sort of my pace putting was really good. So basically just did what you need to do to get a good score around this golf course, and I got one."

Fleetwood shined in a marquee grouping that included world No. 1 Dustin Johnson and Rory McIlroy, as he birdied three holes on each nine. This is his first worldwide start since a T-3 finish at the Hero World Challenge.

It was at this event a year ago that Fleetwood sparked a career campaign, edging Johnson and Pablo Larrazabal for the win. He added another win at the French Open in the summer to go along with a pair of runner-up results and a T-4 finish at the U.S. Open, all of which helped him capture the European Tour's season-long title.

Fleetwood's sudden success in Abu Dhabi serves as a microcosm for his career resurgence. Prior to last year's victory, he had missed the cut in four of his five other trips to this event.

Sergio starts season with 66 in Singapore

By Associated PressJanuary 18, 2018, 12:56 pm

SINGAPORE – Sergio Garcia opened his season with a 5-under 66 and a share of the clubhouse lead on Thursday in the first round of the weather-interrupted Singapore Open.

Playing his first tournament of the year, the Masters champion rebounded after making an early bogey to collect four birdies and an eagle at the Sentosa Golf Club.

He was later joined by American qualifier Kurt Kitayama in the clubhouse lead. Still on the course, Tirawat Kaewsiribandit was at 6 under through 16 holes when play was suspended for the day because of the threat of lightning.

Louis Oosthuizen, the 2010 Open champion, was at 5 under through 16 holes when he also had to stop his round because of the weather.

Of the players who did finish their opening rounds, only three were within two strokes of Garcia and Kitayama. One of them was Casey O'Toole, who aced the par-3 second with a 7-iron.



The 38-year-old Garcia dropped his only shot of the day on the par-4 15th, his sixth hole after teeing off on the back nine, when he missed the fairway and was unable to make par. But he made amends when he birdied the par-3 17th and then eagled the par-5 18th to go out in 33.

''I was 1 over after (the) seventh but it didn't feel like I was playing badly,'' said Garcia, who made birdies on each of the two par 5s and one of the par 3s on the second nine. ''But then I hit two greats in a row for holes 17 and 18. I got a birdie-eagle there, so that settled me a little bit and I could play solid in the back nine and it was a great round.''

Garcia made the shortlist for the Laureus Sports Awards in the Breakthrough of the Year category after claiming his first major at Augusta National last year and is hoping for more success this season.

He credits the Singapore Open as having played a part in toughening him up for his Masters win because he opted to start his 2017 campaign in the stifling humidity of Southeast Asia to prepare himself for the bigger tournaments ahead.

Although he finished tied for 11th in Singapore, Garcia won the Dubai Desert Classic the next week and was in peak form when he won the Masters two months later.

Kitayama only secured his place in the $1 million event on Monday by finishing at the top of the qualifying competition, but he made a strong start with birdies on three of his first five holes. The 25-year-old Thai was 6 under through 13 holes but spoiled his otherwise flawless round with a bogey on his last.

''I started with a birdie and I just let it roll from there. I had some good tee shots, which I think, is the biggest thing for this course,'' Kitayama said. ''I'm a little tired, but I'm hanging in there. Whenever I have time off, I'll try not to think too much about golf.''

13-year-old beats DJ in closest-to-the-pin contest

By Ryan LavnerJanuary 18, 2018, 12:26 pm

Dustin Johnson didn’t just get beat by Tommy Fleetwood and Rory McIlroy on Day 1 of the Abu Dhabi HSBC Championship.

Even a 13-year-old got the best of the world No. 1.

Oscar Murphy teed off on the 177-yard 15th hole as part of the tournament’s Beat the Pro challenge during the opening round. The Northern Irishman, one of the HSBC’s Future Falcons, carved a 3-wood toward a back-right pin, about 25 feet away, closer than both Johnson and Fleetwood.

“An unbelievable shot,” Fleetwood said afterward, “and me and Rory both said, ‘We don’t have that in our locker.’”



Johnson still made par on the hole, but he mixed four birdies with four bogeys Thursday for an even-par 72 that left him six shots back of Fleetwood and Hideto Tanihara after the opening round.

Johnson, who tied for second here a year ago, is coming off a dominant performance at the Sentry Tournament of Champions, where he won by eight shots to strengthen his lead atop the world rankings.

McIlroy 'really pleased' with opening 69 in Abu Dhabi

By Ryan LavnerJanuary 18, 2018, 12:10 pm

It was an auspicious 2018 debut for Rory McIlroy.

Playing alongside world No. 1 Dustin Johnson for his first round since October, McIlroy missed only one green and shot a bogey-free 69 at the Abu Dhabi HSBC Championship. McIlroy is three shots back of reigning Race to Dubai champion Tommy Fleetwood, who played in the same group as McIlroy and Johnson, and Hideto Tanihara.

Starting on the back nine at Abu Dhabi Golf Club, McIlroy began with 11 consecutive pars before birdies on Nos. 3, 7 and 8.

“I was excited to get going,” he told reporters afterward. “The last couple of months have been really nice in terms of being able to concentrate on things I needed to work on in my game and health-wise. I feel like I’m the most prepared for a season that I’ve ever been, but it was nice to get back out there.”

Fleetwood, the defending champion, raced out to another lead while McIlroy and Johnson, who shot 72, just tried to keep pace.

“Tommy played very well and I was just trying to hang onto his coattails for most of the round, so really pleased – bogey-free 69, I can’t really complain,” McIlroy said.

This was his first competitive round in more than three months, since a tie for 63rd at the Dunhill Links. He is outside the top 10 in the world ranking for the first time since 2014.
