39 year old DH: David Ortiz and Alex Rodriguez. Who is more likely to break down?

For months former players and media people were predicting that Alex Rodriguez would be a big distraction and that he would not last until opening day.  Rodriguez has not been a big distraction and he's pretty close to being in the opening day lineup at Yankee Stadium Monday.  Rodriguez has hit with power and played well in a few games in the field, mostly at third but also a couple at first.

Alex Rodriguez

Rodriguez was suspended for using performance enhancing drugs (PED).  Some think that Rodriguez needs PED to perform.

Ortiz was NOT suspended for using performance enhancing drugs (PED).

Rodriguez weighs more than Ortiz?  And which of them would you rather have playing the field?
