A three true outcome All-Star game

Not only was there an above average number of HRs in the game, there was a slightly above average number of walks and strikeouts.

There were 9 walks in 10 IP.  The MLB average per team is 3.3 per 9 IP. So that would be 6.6 for two teams. 9 in 10 is above average.

There were 25 strikeouts in the game or 12.5 per team. The MLB average per 9 IP is 8.5.

Half of the hits were HRs. 10 out of 20.

The average team gets 7.3 non-HR hits per game. So you would expect 14.6 in 9 innings. But in 10 innings there were only 10.
 
Maybe most all-star games are like this. But this game did shatter the HR record.

Today is the anniversary of the "Grich game" when he almost single handedly defeated the Yankees and Ron Guidry in 1979

Click here to go the box score and play by play at Baseball Reference.

Bobby Grich went 4 for 5 (all against Guidry). That included a HR and a 2B with 5 RBIs in a 5-4 come from behind win for the Angels. Grich had a win probability added (WPA) of 1.211, the 9th highest that we know of. Guidry won the Cy Young award the year before while leading the league in ERA. He would lead the AL again in ERA in 1979. This was a home game for the Angels.

Here are Grich's ABs:

1st: Lineout with one out and none on trailing 2-0.

3rd: Single with runners on 1st and 2nd and one out to drive in a run to make the score 4-1.

5th: Single with a man on first and two outs. But next batter makes an out.

7th: Double with runners on 1st and 2nd and one out. Both runners score to make it 4-3.

9th: HR with man on 1st and two outs. Gives the Angels a 5-4 victory in front of 40,739 fans (also in 2 hours 19 minutes).

As mentioned earlier, Grich had a win probability added (WPA) of 1.211, the 9th highest that we know of (using the Baseball Reference Play Index-for games of at least .9, the earliest is 1925). Click here to see all those games. Art Shamsky had a game of 1.503 in 1966, which is the best. WPA uses historical data to estimate how much every change in the base-out-score situation changes a team's probability of winning. The later and closer the game, the more a hit increases WPA.

That famous "Sandberg game" when Ryne hit two clutch HRs off of Bruce Sutter is 42nd with 1.063. I have written about that game. It was impressive, but Sutter was no longer in is prime like Guidry was in 1979. Grich's game is far better. See my post from a few years ago Where Does "The Sandberg Game" Rank In WPA? I explain how hitting a HR off of Sutter was not especially hard at that point in his career.

Guidry as well rested coming into the game. He went 6 innings on July 10th, so he was not over worked. He did face 38 batters in this game, including 10 Ks and 2 BBs. So he could have easily thrown over 100 pitches.

He faced Grich for the 5th time that game in the 9th inning. Guidry's OPS allowed that year when facing batters for the 4th time or more in a game was .863. Pretty high. But the year before it was just .334 and the year after it was .627. So Guidry was not necessarily going to have problems in this situation. In 1977 it was .739

Here is what all AL pitchers allowed facing batters for the 4th time or more in a game in from 1977-80 with the league average OPS for all PAs after it in parentheses.

1977: .746 (.735)
1978: .719 (.711)
1979: .765 (.743)
1980: .766 (.731)

So batters did somewhat better facing a pitcher for the 4th time or more, but in the two previous years, not by much. Yes, Guidry faced Grich for the 5th time in the 9th. But he was the Cy Young award winner the previous year (with a 1.74 ERA). So it is not surprising a manager would stick with him.

Rich Gossage, one of the Yankees' best relievers, worked 3.2 innings the day before and another good righty reliever, Ron Davis had pitched 2.1. Davis also pitched on July 13th. Looking at the Yankee roster, those guys seem to have been the best possible options.

Grich was a righty and Guidry was a lefty. But Guidry did not get hit that hard by righties. Here are his HRs allowed divided by PAs for the years 1977-80:

1977: 9/606
1978: 11/757
1979: 17/776
1980: 12/729

So a manager would not have worried too much about Guidry having to face a righty.

Here is the OPS Guidry allowed vs. righties:

1977: .629
1978: .561
1979: .667
1980: .724

Here is the OPS Guidry allowed during innings 7-9:

1977: .677
1978: .428
1979: .755
1980: .659

Again, no big indicators that it would be a problem to leave Guidry in. Grich did hit 30 HRs that year but before that he had never hit 19. He did have 18 HRs in 358 PAs thru July 14, which is a pretty good total.

Here are his OPS vs. lefties:

1976: .794
1977: .807 (in only 50 PAs, he was hurt)
1978: .796
1979: .909 (but it was .900 vs. righties)
1980: .547

So it looks like there would have been no reason for a manager to especially fear Grich when facing a lefty. Good, but not devastating numbers.

Update 7-16-18: Grich had only faced Guidry 7 times before this game in his career and only once before that season. Grich was 2 for 7 with a single, a double and 3 strikeouts. Sandberg had faced Sutter 12 times including 4 times that season.

Was Bobby Murcer one of the most underrated players of the '70s?

That is what someone said on Twitter today. But who underrated him? How do we measure that?

I have tried to estimate this before and links are provided below. If you read them and click on links to the complete rankings, Murcer does not appear to have been underrated.

Here I just looked at where he ranked in WAR among position players and in MVP shares among position players. Here are the WAR leaders from the 1970s using the Baseball Reference Play Index

WAR leaders of the 1970s.

Murcer is 38th.

I also copied and pasted all the MVP votes from 1970-1979 from both leagues into Excel and found the cumulative total for each player.  I took out any pitchers. Murcer is 36th, very close to his rank in WAR. So it seems that he was rated just about right by the MVP voters. He had three top 10 finishes (a 7th, a 5th and a 9th).

Was Willie Mays The Most Underrated Player In History? Or Was It Wade Boggs? Is Albert Pujols The Most Overrated? (Revised)

Mariners specialize in high leverage situations

Now you might think it is just a good bullpen. But they hit much better in high leverage situations, too. Overall, the Mariners have an OPS of .742 and have allowed .709. That .033 differential is modest. Using my regression generated formula of

Pct = .5 + 1.3*OPSDIFF

That gives them about a .543 pct when it is actually .632. So they have won about 8 more games than expected (they are now 55-32).

Here is what their hitters are doing. Data from Baseball Reference.

Split BA OBP SLG OPS
High Leverage 0.298 0.357 0.505 0.862
Medium Leverage 0.268 0.330 0.414 0.744
Low Leverage 0.235 0.296 0.388 0.683

Now what the pitchers allow.

Split BA OBP SLG OPS
High Leverage 0.250 0.313 0.361 0.674
Medium Leverage 0.241 0.298 0.407 0.705
Low Leverage 0.246 0.306 0.426 0.731

Now the OPS differentials. So they play like the 1927 Yankees in High Leverage situations (the Yanks that year had an overall differential of .196).


Split OPS OPS Diff
High Leverage 0.862 0.674 0.188
Medium Leverage 0.744 0.705 0.039
Low Leverage 0.683 0.731 -0.048
