The Opsera is a statistic RealGM Executive Editor Chris Reina created in order to objectively rank teams by how well they hit (OPS) and pitch (ERA). In order to determine the Opsera rating for each, we take their OPS, multiply that number by 10 to move the decimal point over one place to the right and then subtract their ERA from that number. Below are the rankings through the Thursday, July 19th games: The rankings from last week are in parenthesizes. 1. (1) New York Yankees - 4.31 2. (2) Texas Rangers - 4.15 3.

Prince Fielder joined Ken Griffey Jr. as the only players to win multiple Home Run Derby titles on Monday night at Kauffman Stadium. Fielder thrilled the crowd with several shots into the right-field fountain, beating Toronto's Jose Bautista 12-7 in the final. "Just being mentioned with him is real special," said Fielder, who spent time at Griffey's house when he was a kid. "My dad would let me go over and play video games all day. He always took care of me when I was a kid."
