"We knew that on Draft day," D-backs general manager Mike Hazen said of McLain's decision to attend college. "We really liked him. He was very high on our board. We felt like it was the right pick to make at the time. I'm not going to speak for him, but what was communicated to us was that the right decision for him was to go to UCLA, and we respect that."
The D-backs offered the full slot value of $2,636,400 to McLain, a source said, but that was not enough to get the deal done.
"I'm not going to get into exactly the financial part, but I will say we felt like it was a competitive offer," Hazen said. "I believe that this decision was made not as much on financial grounds, as it was that he felt like the right thing to do was to go to school."
As compensation, the D-backs will receive the No. 26 overall pick in next year's Draft, in addition to their own selection.
Hedging their bets against McLain making just such a decision, the D-backs drafted high school shortstop Blaze Alexander in the 11th round and signed him for $500,000, which was well above slot value.
The D-backs activated reliever Randall Delgado from the 60-day disabled list Friday and designated reliever Fernando Salas for assignment in order to make room on the roster.
