LOS ANGELES — The Dodgers made a roster move before their series finale against the Rockies on Thursday, recalling pitcher Grant Dayton from Triple-A Oklahoma City and optioning Brock Stewart to Triple-A.

The move gives the Dodgers nine relievers for the time being, which will likely change whenever Rich Hill is activated from the disabled list to make his Dodgers debut, which could come as early as this weekend at home.

Dayton pitched two scoreless innings in his major league debut on July 22 in St. Louis, striking out two and hitting a batter in his only MLB appearance to date.

The 28-year-old left-hander has a 2.42 ERA in 38 innings between Double-A Tulsa and Triple-A Oklahoma City this season, with 91 strikeouts and just 11 walks.

Dayton has a 46-percent strikeout rate and despite pitching just 52 innings this season ranks 10th among Dodgers minor leaguers in strikeouts in 2016.

Stewart, who ranks first among Dodgers with 121 minor league strikeouts, heads out after allowing nine runs and four home runs in four innings on Wednesday. He has allowed 14 runs on 18 hits in his first two major league starts.

Dayton pitched in inning and threw seven pitches on Wednesday night for Oklahoma City, his only appearance in the previous four days.
