ESPN Stats & Information put together a look at what Josh Hamilton has meant to the Rangers on the field, looking beyond just his own numbers and how the club has done in general in a variety areas involving Hamilton's bat, glove or speed. Some of the post:
How can we quantify the impact made by Hamilton?
From 2003-07, the Rangers team OPS was .781, they averaged 5.2 runs per game and about 1.3 home runs per game. From 2008-12 – the “Hamilton era” – the Rangers team OPS was .783, they averaged 5.1 runs per game and about 1.2 home runs per game. In other words, the Rangers offense simply remained steady after the arrival of Hamilton.
When one compares the Rangers production to the major-league average over the two five-year spans, it becomes clear just how much better the Rangers’ offense was with Hamilton.
The Rangers’ run scoring went from about 9 percent above the league average to more 14 percent above league average. Similarly impressive advances were made in the team batting average and OPS.
