Humbled by the Orioles, the Dodgers are confident their best baseball is still ahead.

With the league's best run differential and a .628 winning percentage second only to the Atlanta Braves, the Los Angeles Dodgers have yet to hit their stride, according to manager Dave Roberts.

The three-game home series against the Baltimore Orioles this weekend exposed the Dodgers' weaknesses that require reinforcement. On Monday at Dodger Stadium, they were crushed 12-1, losing the series.

The first two contests were decided in the final moments. On Saturday's opener, they edged the Orioles 6-5, but on Sunday, a ninth-inning comeback fell short in a 2-3 defeat.

In today's finale, the Dodgers fell into a big hole early, and the gap only widened.

Starter Emmet Sheehan was off from the start, allowing five of the first six batters to reach base. He surrendered only two runs in the first inning, but the Orioles added solo homers in the second and third to keep building their lead.

With one out in the fourth, Sheehan walked two straight batters, reaching 82 pitches. Roberts quickly pulled him for Jack Dreyer, who let both inherited runners score. Sheehan's six earned runs marked a season high.

The Dodgers' lineup initially troubled Orioles starter Brandon Young, with Max Muncy delivering an RBI single in the first inning. But that turned out to be their only hit with runners in scoring position for the entire game.
