LOS ANGELES -- Which unsavory statistics will blink first?

The Reds are 9-22 on the West Coast since 2006 and 7-17 on the road this season. They've dropped the first three games of a seven-game California trip at Los Angeles, including Wednesday's 5-2 defeat.

On Thursday, Cincinnati begins a four-game series vs. the Padres -- owners of the Majors' worst record. San Diego has lost its last five of six games.

The Reds are 14-9 at home and pitch much better at Great American Ball Park, which is a haven for offenses. The team's home ERA is 3.64 compared to 5.52 on the road. Offensively, Cincinnati is batting .255 at GABP and .260 on the road.

If the Reds lose one more game on this trip, they will return home with another sub .500 journey. They've already lost 18 of their last 19 road trips since 2006. The only winning trip in that span was Aug. 14-19, 2007.

Last season, the Reds were 33-42 at home and 33-48 on the road. The ERA and team average were almost the same though.

Reds manager Dusty Baker had no explanation for why his team has had it rough on the road.

"A lot of this was going on before I came here," Baker said. "It's hard to change things overnight. Is it attitude or mindset? I haven't put my finger on it yet. I'm still really assessing things. Some guys are road players. Some guys are home players. I'm trying to decipher a lot of stuff."

Pitching matchup
CIN: RHP Aaron Harang (2-5, 3.12 ERA)
A San Diego native, Harang once again was unable to get anything in the way of run support despite a solid no-decision performance in a 4-2 win over the Indians on Saturday. The right-hander threw seven innings, giving up one run on eight hits with one walk and a strikeout, but the Reds' offense produced just one run while he was on the mound, In his 10 starts, the Reds have gone 5-5 and scored just 3.4 runs per game. Harang is 0-0 lifetime with a 1.00 ERA lifetime in one career game against the Padres.

SD: LHP Randy Wolf (2-4, 5.05 ERA)
Wolf turned in his best outing since May 1 when he faced the Mariners on May 17, allowing three earned runs over 6 1/3 innings with five strikeouts and one walk. He allowed one run before running into trouble in the seventh inning, allowing an RBI double to Ichiro Suzuki in a 10-pitch at-bat that tied the score. Wolf had allowed 12 earned runs in his last two starts.

Short hop:
Reds right fielder Ken Griffey Jr., who was 1-for-4 on Wednesday, has not hit a homer over his last 90 at-bats and remains stuck at 597 career home runs. Griffey's last long ball came on April 23 vs. Houston.
