LOS ANGELES -- The Dodgers recalled right-handed reliever Josh Fields from Triple-A to restock their weary bullpen and made room by placing left-handed reliever Grant Dayton on the disabled list with a left intercostal strain.
Fields pitched a scoreless ninth inning with two strikeouts in Tuesday's 4-3 loss to Colorado.
Fields had been optioned to Oklahoma City on Friday, when the team activated reliever Pedro Baez from the 10-day disabled list. 
Dayton pitched in the past two games, including a hitless inning Monday night, and he likely would have been unavailable to pitch Tuesday night. He has allowed only two hits in 21 at-bats this year.
The Dodgers' bullpen has pitched 15 innings in the past three games. Luis Avilan is now the lone lefty in the bullpen.
