Imanaga, who was pitching for the first time in a week, outdueled Baltimore's Corbin Burnes. Both were picked for the All-Star Game, which will be held Tuesday night.
Imanaga (8-2) gave up six hits, walked one and struck out six in picking up his first victory since June 15th. Burnes (9-4) went six innings, giving up three runs on nine hits while striking out five.
Christopher Morel's home run gave the Cubs the only run they would need. Cody Bellinger, Dansby Swanson, Nico Hoerner and Michael Busch all produced two hits for the Cubs, who have won five of their last six games. Bellinger left the game after he was hit on the left hand by a pitch in the seventh inning by Orioles reliever Cionel Perez.
Ryan Mountcastle posted three hits for Baltimore, which lost for the second night in a row to Chicago as part of a rough start to a six-game homestand leading to the All-Star break.

Kyle Schwarber hit a solo home run, Cristopher Sanchez threw six solid innings and host Philadelphia defeated Los Angeles.

Shohei Ohtani had two hits and an RBI and Miguel Rojas added a single and two RBIs for the Dodgers. Los Angeles starter Gavin Stone (9-3) lasted four and two-thirds innings and yielded nine hits and four runs.
Mariners 2 Padres 0
Bryce Miller fired six innings of shutout ball and Seattle earned its first series win in nearly a month by blanking host San Diego.

Michael King (7-6) was the tough-luck loser, permitting only three hits and two runs (one earned) over six innings. He issued one walk and fanned nine, but it wasn't enough to keep San Diego from dropping its fourth straight game.
Brewers 9 Pirates 0
Rookie Tobias Myers allowed four hits over eight scoreless innings to pace Milwaukee to a victory over visiting Pittsburgh.
