Dustin Pedroia of the Red Sox did. He was announced as an American League starter at second base Sunday and immediately homered (also doubling and singling) in Boston's 8-4 victory over Seattle.
Aaron Hill, who will back up Pedroia July 14 at the 80th All-Star Game in St. Louis, also did. Fittingly, he homered right after Pedroia in the Blue Jays' 10-8 loss to the Yankees.
Of course, Yankees captain Derek Jeter had to. He hit a two-run blast in the fifth inning off Toronto reliever B.J. Ryan in the 10-8 win.
Chase Utley, celebrating an All-Star nod at second base, went deep off of none other than NL All-Star teammate Johan Santana. That provided the final run in the Phillies' 2-0 victory over the rival Mets at Citizens Bank Park.
Prince Fielder did, socking his 22nd homer of the year for Milwaukee after finding out he is among Albert Pujols' backups at first base on July 14. This one came off Fielder's new All-Star teammate Ted Lilly -- similar to what Utley did off Santana.
Even Chad Billingsley did. The Dodgers right-hander helped himself with a solo shot off San Diego starter Josh Banks for his first Major League homer. Maybe he could bat in the NL park.
Both of Houston's new All-Stars did. Miguel Tejada was named to his sixth All-Star squad as a reserve shortstop, and promptly hit a solo shot off Randy Johnson in the first inning at San Francisco. Hunter Pence also was named as a reserve outfielder, and he took Big Unit deep for No. 11 on the season three innings later.
Justin Morneau did. He scored the winning run in the 15th inning of the last All-Star Game. On Sunday, he cracked a two-run homer off Detroit starter Rick Porcello in a big six-run fourth for the Twins, who went on to a 6-2 victory. Morneau, Joe Mauer and Joe Nathan all found out they were going back to the All-Star Game, as they had done together a year ago.
Even the 2009 All-Star Game Final Vote candidates were celebrating with bangs, it seemed. Mark Reynolds of the D-backs homered to help make a winner of new All-Star pitcher Dan Haren. In the AL, Brandon Inge of the Tigers and Adam Lind of the Blue Jays each homered.
