Cardinals third baseman David Freese ended up capturing the roster spot while Yu Darvish of the Rangers won in the American League.
To promote Hill, the D-backs reached out to numerous media outlets, including those in Canada, where the second baseman spent his career before being traded to the desert. The club also printed T-shirts with the hashtag "FinHillVote" printed on them.
Entering Thursday's game with the Dodgers, Hill was batting .300 with 11 homers and 39 RBIs. His two cycles in June highlighted his season so far.
"Aaron is a good, dirty baseball player," D-backs manager Kirk Gibson said. "I haven't seen a game when he hasn't been dirty. He loves the game and is in a good environment. It works for him. He feels comfortable and is finding it."
As of Thursday morning there already had been 40 million votes cast, and there were about six million more between 7 a.m. MST and the close of balloting at 1 p.m. The Final Vote was a continuation of a record-shattering 2012 fan balloting campaign. On Thursday, MLB.com finished the voting for the 17 starting position players via the 2012 All-Star Game MLB.com Ballot, with 391.2 million votes and 34.9 million ballots. Both figures were easily the largest totals recorded in the history of online balloting at MLB.com.
The Final Vote balloting was conducted on MLB.com, club sites and, in a new twist, on Twitter -- where designated player hashtags counted during the final four hours of balloting. The effort drew a four-hour sustained average of 3,000 tweets per minute during the voting period.
