More on Aviles, Punto was brought in because Aviles is a SS or nothing he is not a UIF if he can't play second, third, or RF well enough for WS team.
In 2008, Aviles graded as an excellent infielder, having saved 12 runs above the average defender while shifting between shortstop (his primary position), second and third. After that, however, Aviles graded poorly, costing his team eight defensive runs in 2010 and two in 2011.
Per the book: “His footwork isn’t very good regardless of position, but his range is adequate, and he does have the arm strength necessary to make all the throws from third base or shortstop. However, Aviles is a tentative defender even on routine plays, and he made a lot of defensive miscues, both of the mental and physical variety. He did not appear to take well to the role of a utility man. Overall, his net -11 Good Fielding Play minus Defensive Misplays and Errors was worse than all but eight infielders in the league, regardless of position. If Aviles ever hopes to be looked upon as more than a backup infielder, his glove work needs to improve.”
It is worth noting that Dewan’s assessment of Aviles’ defense was based on his work at third base. Assuming he is the everyday shortstop, Aviles would either need an even more drastic improvement from last year or, if he continues to measure significantly below average, he would need to hit like crazy to offset his shortcomings.
A caveat: One Red Sox team source suggests that the club’s internal metrics (developed by are somewhat more bullish on Aviles than Dewan’s projection system, particularly given his steadily improving arm strength in the post-Tommy John stage of his career.
Curious how Jose Iglesias rates? He doesn’t.
One more footnote in the exercise: Dewan pegged Marco Scutaro as being one run better than league average in both 2010 and 2011 at shortstop. “He remains a solid middle infielder, but at this point in his career he probably will never regain the defensive prowess he displayed across the Canadian border,” said the book.
