Rangers' offense off to slow start

Much attention is being given to the Texas Rangers' offense through 13 games. And for good reason.

The Rangers are 8-5, which is a testament to the their pitching -- especially the bullpen. Joe Ortiz and Tanner Scheppers have answered the offseason's biggest question mark in the early going.

Meanwhile, the offense has put up 49 runs for an average of 3.8 runs per game. The Rangers have scored 30 fewer runs than they had at this time last season when they were averaging 6.1 runs per game.

A deeper look at the numbers through 13 games this season and in 2012 is revealing.

The Rangers were 11-2 at this point last season. Josh Hamilton, Michael Young and Mike Napoli were among the leaders through 13 games last season, and all three left via trade or free agency after last season.
