The lone defense for the Twins trading away Luis Arraez on Friday is that pitching is more expensive than hitting in current Major League Baseball.
Terry Ryan, the former Twins general manager, used a 2-through-8 system to have his scouts evaluate players — prospects, minor leaguers and big leaguers who might be involved in trades.
Eight was all-world, 7 was a perennial All-Star, 6 was a well-above average everyday player or top-line starter, 5 was an average everyday player or midrotation starter … and on down the list.
"I gave an 8 to Joe Mauer as a high schooler," said Mike Radcliff, a Twins vice president for player personnel. "And he was right there as a big-leaguer. There weren't many of those."
As a believer in the strength of the eye test, I was trying to figure out the seismic trade — at least here in Minnesota — and decided on this:
Twins had to give up a "6" position player in Arraez in order to get a "5" starter in Pablo Lopez.
Derek Falvey, the Twins CEO for baseball, was not asked to confirm that evaluation in a brief conversation Friday, but he did make this admission:
"Acquiring pitching is very expensive these days."
