Depends on what you mean by "Good Day"

As the days get colder, the shadows longer, and the sun shines DIRECTLY IN THE BATTERS EYES off the windows an astute wiffler knows the season is winding down to a winter hibernation. With no championship on the line, what's left to play for is your stats. To be sure it's still good to win a game as well. But with every game now, you know in the back of your head this could be it for the season. Under these circumstances, what makes a good day on the asphalt? Well, it depends an what you mean by "good day." 

Two case studies: Mark and Dewey.

First, the Dewey. Dewey brought two new players, which is a good day. This is really Dewey's thing, ya know? He's the reason Zach is blasting homers and striking out batters in this league. Today Dewey brought his son-in-law Markiel and fireballer Bob B. Dewey got to play a full game of wiffle on a brisk, sunny fall day with his family and friends. It was a good day... until he surrendered 6 runs in the 8th inning to put his team in a 7-6 hole on the scoreboard. Dewey had a good day at the plate: 5-for-11 with a homer and 3 RBI... until he struck out to end the game with the winning runs aboard.

Mark also had a good day. At the plate: a very Dewey-like 5-for-11 with a Grand Slam and 4 RBI. The key figure in that line is the "eleven." I looked it up: eleven is less than fifteen, so you can trust me on this. Mark needed 15 ABs to qualify for the batting title, but he fell 4 short. 15-11=4. Mark's team won (which is good) basically because he hit that Grand Slam (off Dewey, btw, which is good). It was a good day. But if there are no more days this year, he will fall 4 ABs short of a batting title, and might make this seem like less of a good day.

So who had a good day and Nance Bradds Field today? Limit your answer to 750 words, and defend your argument using either mathematics or philosophy (but not both - that would be pretentious or prehensile).

Adrian, Mark, Matt, Pete - 7 runs, 18 hits
Bob B., Dewey, Markiel, Zach - 6 runs, 19 hits

HR: Darden (4); White (4)
