Obviously you don't have to have a degree to hit a curveball, and that's great news for Major League Baseball players who are lacking when it comes to college degrees.

A grand total of 39 MLB players who have played this season have earned a college degree. Keep in mind that 917 men have appeared in a game as of Wednesday morning, so that means just 4.3 percent of ballplayers have acquired four-year college degrees.

It's not totally shocking when you consider a large percentage of players are drafted right out of high school and others come to America from foreign countries to play ball.

First of all, Fox Sports Jon Paul Morosi reports, the Arizona Diamondbacks are the most educated club with seven players who have obtained four-year sheepskin. J.J. Putz (Michigan), Willie Bloomquist (Arizona State), Craig Breslow (Yale), John McDonald (Providence), Takashi Saito (Tohoku Fukushi University Japan), Mike Zagurski (Kansas) and Brad Ziegler (Southwest Missouri State) are the players.

"I am thrilled to see we have the most educated players, but they are only as smart as their win/loss record," Diamondbacks club president Derrick Hall explained to Morosi when told of the numbers from Stats Inc.. "I happen to believe our guys are as smart as any, but fans want to see wins. Where I do see the difference is with an educated group that understands the business of the game, the importance of the fan and the significance of giving back to the community. That can be linked to education and a strong level of common sense."

Meanwhile, the floundering Houston Astros are tied with the Tampa Bay Rays with the second highest total of college grads in the majors at four each.

Alex Rodriguez and Derek Jeter are the headliners in the Bronx, but Curtis Granderson is the only 2012 New York Yankee with a diploma. Grandy Man, the son of teachers, returned to school to earn his degree in business management and business marketing from the University of Illinois-Chicago.

"It's very difficult to do," Granderson told FoxSports.com. "A lot of stuff had to line up for me to get the opportunity to go back to school. "First, the individual has to want to do it. School's not necessarily for everyone."

By the way, Morosi notes that more than 60 percent of amateur contracts signed in 2011 by players born in the U.S., Canada and Puerto Rico includes some form of scholarship money. Yet if the trend continues, 56 percent of that cash will be wasted.

In short, 43.3 percent of Major League teams don't have a single college graduate on their roster.

Among that uneducated baker's dozen, Bobby Valentine's Boston Red Sox lead AL clubs, and the list includes the Chicago White Sox, Cleveland Indians, Detroit Tigers, Kansas City Royals, Oakland Athletics and Seattle Mariners.

The senior circuit is more educated, that is to say 11 teams are represented by at least a single player with a degree. The Atlanta Braves, Washington Nationals, Cincinnati Reds, San Diego Padres and Pittsburgh Pirates are N.L. clubs without a graduation situation.
