The Cincinnati Reds recalled right-hander Jordan Smith from Double-A Carolina and optioned right-handed reliever Enerio Del Rosario to Triple-A Louisville before Tuesday night's game against the Los Angeles Dodgers in Cincinnati.
Smith, who's never pitched above the Double-A level in five professional seasons, was 1-3 with a 5.08 ERA in 27 relief appearances for the Mudcats.
In two stints with the Reds this season, Del Rosario was 1-1 with a 2.08 ERA in nine games.
The Reds bullpen has a 4.74 ERA, which is 24th in the major leagues and 13th in the National League.
More bullpen moves are expected in the near future, according to several reports.
Tuesday's game between the Reds and the Dodgers in Cincinnati was delayed in the top of the fifth inning because of thunderstorms.
The game restarted shortly after 11 p.m. after a delay of 2 hours and 24 minutes.
Billingsley headed to DL
The Dodgers plan to put pitcher Chad Billingsley on the disabled list because of a groin injury.
Billingsley hurt himself during his last inning on Friday against the Angels, Manager Joe Torre said.
The right-hander tried to throw before Tuesday night's game against Cincinnati, but Torre said a high groin pull tightened up.
Billingsley is 6-4 with a 4.34 ERA in 13 starts.
The Dodgers will call up a relief pitcher, Torre said. The rotation will be juggled, with John Ely moving up a day to start Thursday's series finale in Cincinnati.
Wood strikes out 10
Reds pitching prospect Travis Wood pitched seven innings in Triple-A Louisville's 2-0 loss to the Pawtucket Red Sox on Tuesday night.
Wood allowed two runs — one earned — on four hits and one walk. Wood struck out 10 PawSox, one shy of his season-high.
Wood (4-5, 3.56) has been among the names mentioned to join the struggling Reds bullpen.
