Frazier, Navarro in for Rolen, Hanigan in Game 4

CINCINNATI -- For the first time in the National League Division Series, there were changes in manager Dusty Baker's lineup vs. the Giants in Game 4 on Wednesday.

Third baseman Scott Rolen was out and rookie Todd Frazier was in. At catcher, Dioner Navarro replaced regular catcher Ryan Hanigan and was starter Mike Leake's batterymate.

Reds vs. Giants

Although Hanigan's passed ball and Rolen's fielding error led to the Giants' go-ahead run scoring in the 10th inning of the Reds' 2-1 loss in Game 3, these were not benchings by any stretch. Baker usually has lineups in mind ahead of time.

"This is the same thing I have been doing all year long," Baker said. "I usually don't play Scott after day games. Even though this is an afternoon game and yesterday was an evening game, it's a situation where I'm going to get asked no matter who plays."

Frazier, who had an at-bat each in Games 2 and 3, batted .275 with 19 home runs and 67 RBIs in 128 regular-season games that made him an NL Rookie of the Year candidate.

He did not find out about his first postseason start until Wednesday morning.

"I'm very excited," Frazier said. "I've got a couple of people here in town, and I couldn't ask for anything better. It's a good matchup for me, and I know I don't need to do too much. I just need to get on base, get guys in. I just need to have fun."

His group of supporters in the stands included his parents and his fiancée, Jackie, and her parents, all of whom traveled in from New Jersey.

Navarro, who was called up in late August from Triple-A Louisville, batted .290 in 24 games. He was also Leake's catcher over the right-hander's final six starts of the season.
