Rogers Masters Part Deux

Black Friday has come and gone and Movember is nearly over. The Toronto Argonauts just won the 100th Grey Cup with the quarterback Edmonton moved at the end of last season. Before we get to Part II of last weekend's Masters of Curling, I need to take a moment and plug Around The House, a new Podcast covering the sport of curling. It's hosted by Manitoba's Jordan Bauldic and includes yours truly along with CurlingZone Czar Gerry Geurtz. We're hoping to get an RSS feed set-up soon.

An important note for those gamblers out there.  Curling gambling is underway at Sports Interaction

And now, back to our analysis...

Let's return to the Friday round robin game between Glenn Howard and Kevin Koe, the one I was too tired to expand on in Part 1.

The 5th end (Howard up 2-1) is intentionally blanked by Koe. The intention is to have hammer in the 6th and 8th (final) ends, leaving Howard with hammer in the 7th. This occurs if no end is blanked or stolen. The idea is to go "2 for 1" (2 hammers to one for your opponent). Let's examine this play.

Down 2-1 with hammer with..
4 ends remaining = 40.4%
3 ends remaining = 39.0%

This is very close. Koe isn't losing much by blanking but it doesn't appear that he is gaining either. Let's compare odds based on outcome in the 5th end and 6th end:

Up 1 without hammer (take 2) = 61% (score in 5th end) / 64.4% (score in 6th end)
Tied without hammer (take 1) = 35.9% / 32.9%
Down 2 with hammer (steal of 1 by Howard) = 19.3% / 15%
Up 2 without hammer (take 3) = 80.7% / 85%

Kevin is essentially blanking in order to attempt a deuce in the 6th end to gain 3.4% from scoring two in the 5th end. Note that the reduced odds he would see by being forced to one in the 6th instead of the 5th is 3%. The net of this is a 0.4% gain. A steal (bad) or three (good) is 4.3% better or worse in the 6th versus the 5th end.

Let's look at this another way. Taking two then forcing Howard to one. If Koe does this in the 5th and 6th ends, his odds to win are 67.1%, tied and two ends to play. If he blanks the 5th, takes two in the 6th then forces in the 7th his odds become 79.7% (tied with one end). Remember, general stats for all events show 75% odds if tied with hammer and one end to play but Grand Slams trend closer to 80%.

Now we can see that Koe is putting more pressure on the outcome of the 6th with the goal being a 12.6% improvement if he achieves the same results (take 2/force 1). This gain more than compensates for a steal or force in the 6th versus the 5th end and makes a strong case for this strategy.

Koe is forced to one in the 6th and then the 7th end results in Howard looking at this before third Wayne Middaugh's last rock:

Howard is Red
They take nearly 6 minutes (including 1 for a time out) before Wayne launches his stone. This shot resulted in Glenn being rushed at the end of the game. Ironically, earlier this end Joan mentions that strategy is not an issue for these teams and before that Mike Harris mentioned that Glenn is the best in the world at understanding rock positioning.Wayne makes a perfect shot, hitting a piece of the red in the top four foot and moving both yellows out:

Howard now sitting two. In this situation, Howard is trying to score two (88% winning percentage) at the risk of a force to one (60%) or even giving up a steal and having last rock in the last end down one (40%). Ultimately, I agree with the call (and not just because Wayne made it so well). Glenn only needs two to maximize his chance for a win. Any more is just a bonus. I prefer moving the stones around at this stage because bunching more rocks into the area would increase the odds of a steal and bring in a possible steal of two (disaster).

Even if Wayne had killed the red rock off the button, Glenn may still have a possible chance at two but greatly reduced chance for a steal. I'm just surpised it took them so long to recognize the shot.

Kevin then makes a great shot to sit just on top of the Howard stone. After Glenn peels the guard, Kevin puts another one up and Glenn still had a slight chance at two with a very difficult draw. Didn't make it, and he heads to the final end up one without hammer.

Gerry Guertz gets a little video shot in the booth on at the beginning of the 8th end. Did I mention that I'm joining Gerry on a Curling Podcast called Around The House, which is hosted by Jordan Bauldic? Sorry if I missed that.

In the 8th end (Howard up 1 without hammer), Glenn calls for Middaugh to play a straight back raise with board weight. Wayne hits it high side and rolls for a corner. Without hammer, Howard needs to keep the centre guard and though that was the intent (reason for lighter hit weight), they don't get that result. This changes the entire end and puts Koe into a position to take two with reduced risk of a steal. Wayne actually makes up for his miss with a spectacular shot (shown here in telestrator slo-mo instant replay):

Howard is Red

Wayne misses the yellow stone on the button but leaves the raised stone sitting in front of it.

Koe's third Pat Simmons then draws around the corner again and a timeout for Howard as they try to decide what to call. At this stage they have 1:01 left on their "talk-time" clock. Glen makes a great tap and corner freeze, sitting 2nd and a very close third shot it appears.

Howard is Red

Koe attempts to tap the red in front of his shot stone back button but is too heavy and wide and leaves a very makeable double. Glenn has under 40 seconds to make this attempt, plenty of time but cutting it very close. He throws the stone to the high side and misses the double, leaving a fairly simple shot for two and the win for Koe. If only the center guard had still been there or a little more time on the clock.

Kevin Martin vs Jeff Stoughton in the Quarterfinal.

First end of this game and both teams are knee deep into it. 4 rocks in the four foot, 3 more in the eight foot, one in the twelve foot and two guards out front (10 in total and 2 yet to come). Jeff makes a great tap to sit one and Kevin then follows with a double tap to take 1.

In the 5th end, up 2-1 without hammer, Martin's first rock thrown by Ben Hebert is a longish guard. Not sure if that was an error or intentional, we didn't join the broadcast until later in the end. Once Stoughton gets a rock buried top eight foot, Martin lead Ben Hebert is light, top twelve foot. Stoughton begins to throw rocks out to the side, drawing for second shot. Joan and Mike comment it's not a common sight, playing away from the center.  Seemed to make sense given the situation, but agree we don't see it often.

By the time we reach Kevin's final rock, he's facing this:

Martin is Yellow

Kevin attempts the thin double (red lines) rather than the soft weight hit and roll (green line) to the centre. Martin's top yellow sits a well protected third shot. A very aggressive call that I think many players, even at Kevin's level, would not have attempted. He hits the top rock too thick, and surrenders a deuce to Stoughton.

In the 6th, Kevin has a great chance to get two back but comes heavy on his first and Jeff locks his last shot on top of Kevin's, forcing him to a very difficult draw to the side of the pin for two, which he doesn't make.   Score is 3-3 after 6 ends.

At this stage, everything seems to be going Stoughton's way.

In the 7th, Team Martin called time out John Morris final shot, facing this:

Martin is Yellow

They take a moment to discuss the various angles, what they will leave Jeff and what they expect him to call.  Eventually they call a freeze/tap on the second shot yellow stone (based on lead Ben Hebert's suggestion). It's made perfectly. After a hit by Stoughton's third Jon Mead, Martin is facing a similar shot and makes the same freeze. Eventually, Jeff has a double attempt to score one but the result is a steal for Martin.

After a Marc Kennedy triple peel, Kevin chooses to play the 8th rather open, trying to force Jeff to one and go to the extra end with hammer. Jeff in fact misses his last shot, an open hit that needed to stay in the four foot, and Martin steals one and moves on to the semi-final.

The next broadcast is a quarterfinal with Laycock (a Tier 2 qualifier) versus Brandon Jacobs. My Tivo worked overtime here as the first three ends were blanked. After a deuce in the 4th by Laycock, Jacobs attempts a difficult split on his last in the 5th and only manages a single. He dropped from odds of 19.3% (2 down with hammer) to 16.9% (one down without hammer), attempting to tie the game (39%). Well worth the risk if he has even a 15% chance to make it.

Semi-final: Battle of the Kevin's, Koe versus Martin.

$1 million dollars, announced at the beginning of the week, must still be in the minds of these players. Despite the $1 million, they still can't appear to get more than a couple dozen people into the stands. I know it was an early moring draw, but most curling fans are over 60 and usually up by 6 am.

The game appears a little sloppy, though I heard later from Gerry Geurtz (on the Around The House podcast) that there were issues with the ice. Kevin Martin calls a difficult soft hit on his first shot of the game, rather than blasting, and if Koe had been an inch further with his last, they may have stolen three. Instead, it's a steal of two when Martin's last rock draw is heavy.

In the 4th end, Koe is up 3-1 without hammer, With two red rocks in the top rings, he chooses to place a guard rather than peel the Martin corner guard. An aggressive play which surprises me. I think if Koe had only one in the rings he may have blasted the corner. Martin ends up able to play to the wings and if not for a miss by third John Morris, would have been well positioned to score more than one. Instead, Koe is able to place a rock biting the top four foot and Martin eventually comes heavy on his draw, leaving Koe a steal of one (and almost two).

Martin scores a deuce in the 5th, despite one of Morris' shots picking (they were drawing to sit three at the time). Kevin Koe attempts a raise double on his last and can't remove one of Martin's rocks, but sits 2. Martin makes no mistake with the double and pulls within 1, 4-3 for Koe.

Up 5-3 without hammer in the 7th, Koe's squad takes an incredibly long time deciding whether or not to have second Carter Rycroft peel on his last shot. They do peel and their fears of a draw around their staggered rocks in the house are avoided when John Morris comes heavy with his first shot draw attempt. Koe third Pat Simmons blasts the rocks in the house and result in an eventual blank.

At the start of the eight end they show Jack Nicklaus, Roger Federer and Kevin Martin, and their respective "Grand Slams". I fully expect Jack and Roger have no idea how close they are to being usurped. Also hope Jack did not see the photograph as it appeared he had three chins.

Pat Simmons misses a couple of shots badly, flashes a peel and heavy on a draw. Morris misses his last, moving the centre guard. Koe eventually faces this with his final shot:

Martin is Yellow

Koe's squad discusses the last shot, trying to ensure they don't risk giving Martin a chance at a possible three, which will lose the game. Rather than playing a freeze, Koe decides to play a double on the top two yellow. He ends up kissing his own red on the button to the back of the rings and leaves a possible shot for three. It's not an easy shot and Martin hits it a little thick and only gets one.

Off to an extra end, Koe with last rock.

On Kevin Koe's first shot, he's looking at this:

Martin is Yellow

After much discussion, they decide to play the peel.  They consider playing into the rings now, worried that the last shot will be difficult.  Because of the red corner guard, the draw to the button in not routine (like they usually are :).  If Martin makes a perfect shot, they may have to play a double to blank.  Kevin Martin attempts a hit but rolls slightly to the open side, leaving Koe and draw ot the four foot.  A little heavy, but hangs on by a hair (and a measure) for the win.

Koe goes on to battle in the finals against BC's Jim Cotter (with Manitoba import Jason Gunnlaugson at third).  After a steal of two in the first, Koe rebounds with a deuce of his own and, after a force in the third, cracks a three ender in the 5th to go ahead 5-3.Unlike the Martin game in the semi-finals, it never gets closer and they take home the top prize and sole possession of the title "only team that can win the grand slam and $1 million dollars".

Until the Canada Cup...
