Albert Pujols, a three-time Derby participant, campaigned to Cano that his teammate be in Monday's Derby at Kauffman Stadium in Kansas City. And Trumbo has already gone to Vernon Wells, a 2010 Derby contestant, and former Angels slugger Garret Anderson, the '03 Derby champion, for advice.
They've told him the usual -- "Take your time, have fun, use the whole field" -- but what Trumbo most needs to avoid is the famed post-Derby slump like so many participants, excluding Anderson, have experienced.
Though there are extreme cases like the Twins' Justin Morneau in 2007 (26 homers before the Derby and just seven after) and Bobby Abreu in 2005 (18 homers and a .307 average before the break and just six homers with a .260 average after), most players were at or near their home-run-per-plate-appearance pace before and after the contest.
Even though 30 out of the 40 Home Run Derby participants from 2007-11 saw declines in their homers-per-at-bat totals after the All-Star break, most were minor regressions.
"I think there's always a risk of that. Garrett Anderson won it and had an incredible run in the second half," manager Mike Scioscia said. "Everybody's an individual. I don't think you can say it one way or the other. It is a lot of work, the Home Run Derby, if you go the whole way."
Still, Trumbo isn't concerned with a dropoff after the break. Despite the potential for more than 100 swings in the competition, Trumbo said if he wears down in the second half of the season because of a Home Run Derby, there's a problem.
"I feel, as a professional athlete, it's my job to stay in shape," Trumbo said. "So if I get tired after however many swings it is, that's probably not a good sign."
