If your blood glucose level is higher than 250 mg/dl, you do not have ketones in your blood or urine, and you want to exercise, I recommend starting your workout then stopping after 15 minutes to see if your blood glucose level is rising or dropping.
Outfielder Ty Cobb, whose career ended in 1928, has the highest batting average in Major League Baseball (MLB) history. He batted .366 over 24 seasons, mostly with the Detroit Tigers. In addition, he won a record 11 batting titles for leading the American League in BA over the course of an entire season.
Ty Cobb retains the title of player with the all-time highest career batting average, .366. Make the Calculation. Fortunately for rabid baseball fans everywhere, calculating a player's batting average doesn't take advance math. Just divide the number of base hits the player gets by the number of times he's been at bat. For example, if a player has been at bat 520 times and has gotten 179 hits, his batting average is 179/520, or .344. Walks do not count as an at-bat, and neither do sacrifice flies or bunts or getting hit by a pitch.
