The big fix for the next Padres GM

ANAHEIM, Calif. -- As folks in the baseball world waited for San Diego Padres GM Josh Byrnes to be fired last week, a rival executive ticked off the performances of San Diego's various position players and noted how Murphy's Law was embedded in the entire lineup. What could go wrong has gone wrong.

Just take a journey around the field, starting at catcher: Yasmani Grandal batted .297 in 60 games in 2012 before being hit by a Biogenesis-related suspension last year. He is hitting .191 with a .643 OPS this season. That ranks last among all players with at least 150 plate appearances at his position.

First baseman Yonder Alonso, who hit .273 in 2012 and .281 in 2013, has hit just .210 this season with a .591 OPS -- last among qualified first basemen in the big leagues.

Second baseman Jedd Gyorko, who hit 23 homers last season, has a .483 OPS this season while battling foot problems.
