"He's very deserving; he's one of the best relievers in baseball," Padres manager Bud Black said. "I do know that he was given strong consideration, and on the players, coaches and managers' vote, he fared well.
"In this day and age, with the specialization of pitching staffs and how deep bullpens are, there are a lot of great relief pitchers out there."
Since the beginning of the 2009 season, Adams has allowed the lowest opposing on-base percentage (.217) among Major League relievers, the lowest ERA (1.34) and the second-lowest opponent's batting average (.162).
"I definitely thought I deserved to go, but the other guys who made it deserved it," Adams said. "I know how tough it is for setup guys to make it. It [making the All-Star team] has meaning, but it's not going to change anything for me, how I prepare."
The Padres felt as though third baseman Chase Headley was also deserving of a shot to make the team as a reserve or as a Final Vote candidate.
Headley entered Sunday's game against the Mariners with the highest batting average (.311), on-base percentage (.404) and OPS (.819) among National League third basemen, and was tied for second with 84 hits.
"I think everyone in the Major Leagues would love to play in an All-Star Game, and so would I," Headley said. "It would be awesome to experience that.
"But I wouldn't say that I'm disappointed. There will always be guys who deserve to make it and don't. That's just the nature of it."
Headley was hitting .211 on April 27, but since then is hitting .345 in his last 200 at-bats with a .425 on-base percentage. And since June 1, he's hitting .370 with a .442 on-base percentage over his last 100 at-bats.
"I'm excited with the way I've been able to play the last couple of months," Headley said. "It's a grind, but let's just keep it going. I'm happy that we're even talking about it [All-Star Game consideration]."
