This is probably not the place to have this discussion but it started here. Here below is the best statistical data I can find for my impression of AGonz when the Sox really needed him in 2011. These are the splits for Pedroia and Agons for game situations when the Sox were ahead vs game situations when the Sox were behind. Agons is being mentioned in the same breadth with Pedroia for his production when the Sox really needed clutch performance in 2011 and I think this data below says otherwise. By the way, you should not expect to see the numbers total to 162 in the "G" Games column because Games here represents Game Situations when the Sox were either ahead or behind.
When I first looked at Agons stats it made sense that his stats for game situations with the Sox leading should be better than they were for the Sox trailing. However, should they be so wide? AGons total stats are as good if not better than Pedroia's in many categories. However the stats clearly show that AGons was collecting most of his numbers by a very wide margin when the Sox were already ahead in games. Pedroia was collecting almost as many of his numbers when the Sox were behind as when they were ahead. Look at BA, OBP and SLG. Pedroia's numbers are very close, easily within range of the simple difference between the number of times the Sox were leading in 2011 vs the number of times they were behind. In fact in some cases Pedroia's numbers were better when the Sox were behind than when they were ahead regardless of the fact that Pedroia came to the plate more with the Sox leading than trailing. Whereas Agons numbers are widely disparate and always much better when the Sox were leading than trailing. Look at BA, OBP, SLG and OPS comparisons for example.
This is exactly the impression I had of Agons performance vs Pedroia's when watching them play. Pedroia was just as effective when the Sox needed to come back as when they were ahead. AGons was collecting a good many of his numbers when the Sox were ahead and the comparative difference when the Sox were behind was huge.
The first data set below is for Pedroia and the second is for Agons.
