No NL second baseman has started four All-Star Games in a row since Craig Biggio from 1995-98.
"He works hard," Phillies manager Charlie Manuel said of Utley. "He stays after it. He loves to play and he's determined. His determination is off the chart. He puts everything he's got into it."
No NL second baseman has started five or more consecutive All-Star Games since Ryne Sandberg started eight consecutive games from 1986-93.
"Chase is a true professional," teammate Raul Ibanez said. "He's amazing. His work habits are something to admire. Watching him every day is inspiring. He wants to be the best and he strives for it."
The last NL player to start four consecutive All-Star Games at any position is Mike Piazza, who started at catcher from 1994-99.
