MLB shows frustration with A-Rod

Major League Baseball had this message for Alex Rodriguez and agent Scott Boras: Shame on you.

Boras announced during Game 4 of the World Series on Sunday night that A-Rod was opting out of the final three seasons of his contract with the New York Yankees. The timing left baseball officials livid, and Boras apologized Monday evening, just after Rodriguez filed with the players’ association and became a free agent for the first time since 2000.

“We were very disappointed that Scott Boras would try to upstage our premier baseball event of the season with his announcement,” Bob DuPuy, baseball’s chief operating officer, said in an e-mail to the Associated Press.

Boras said causing a distraction was an unintended consequence.

“I apologize to the Boston Red Sox and Colorado Rockies and their players, Major League Baseball and its players, and baseball fans everywhere for that interference,” he said in a statement.

Tigers pick up Renteria

The Detroit Tigers filled their No. 1 need, acquiring All-Star shortstop Edgar Renteria from the Atlanta Braves for two prospects.

“We were able to address our biggest need, heading into the winter, with one of the best shortstops in the game,” Tigers president and general manager Dave Dombrowski said on a conference call.

The Tigers gave up right-hander Jair Jurrjens, who showed signs of promise last season, and minor league outfielder Gorkys Hernandez.

Detroit went into the offseason needing to add a shortstop after deciding to shift Carlos Guillen to first base.
