Thirteen. That’s the word of the day. Defined, it means one less than twelve, the sum of six and seven, or the amount of runners the Red Sox left on base tonight. The margin between winning and losing a baseball game is often minuscule. You only get so many chances and to win games you have to take them. The Braves even gifted the Red Sox base runners with multiple errors throughout the game, but the Red Sox never took advantage. Games like tonight, against a right-handed pitcher remind me that Triston Casas is on the IL. His plate discipline and ability to hit the ball to all fields lengthens the lineup, makes things so much more difficult on the pitcher, and ultimately makes the team better.
