Kamieniecki Has Strained Left Groin

The Baltimore Orioles put pitcher Scott Kamieniecki on the 15-day disabled list Sunday because of a strained left groin.

Kamieniecki will be replaced on the roster by right-hander Nerio Rodriguez, who was recalled from triple-A Rochester. Rodriguez will start Wednesday on the road against the Chicago White Sox.

Kamieniecki (2-1) had been bothered by the groin strain since spring training. The right-hander has a 6.46 earned-run average.

Kamieniecki, 33, struggled in both his previous outings. He gave up four runs in five innings against Texas on April 18 and was shelled by Oakland on Friday night, yielding six runs in one-third of an inning.

Last year, Kamieniecki was 10-6 with a 4.01 ERA in 30 starts.

“We looked at films comparing him to last year, and his mechanics are really different,” Miller said.

Rodriguez, 25, was converted from a catcher to a pitcher in 1995.

The right-hander was 0-3 with a 6.14 ERA in three starts with Rochester. He walked five and struck out 12 in 14 2/3 innings.

The Oakland Athletics put outfielder Jason McDonald on the 15-day disabled list Sunday and activated pitcher Mike Fetters from the DL.

McDonald strained his left groin April 18 in a game against the Kansas City Royals and had not played since, so the move is retroactive to April 19. McDonald is hitting .333 with a team-high six stolen bases.

Fetters strained his left calf muscle coming off the mound while chasing a foul ball on April 5 against the New York Yankees. The right-handed reliever is 0-0 with a 4.50 ERA in two appearances.
