CLEVELAND -- One of the Indians' offseason investments is headed to the disabled list. Another is headed out the door.
As expected, the Indians placed David Dellucci on the 15-day DL on Wednesday with a strained left hamstring the outfielder suffered Tuesday night. He will be replaced on the active roster by outfielder Ben Francisco, who was recalled from Triple-A Buffalo.
In a less expected move, the Indians cut ties with right-handed reliever Roberto Hernandez, who was designated for assignment. He will be replaced in the bullpen by right-hander Ed Mujica, who was also promoted from Buffalo.
The Indians will have 10 days to trade or release Hernandez, who gave up three runs in the ninth inning of what had been a one-run ballgame Tuesday night against the Phillies.
Signed to a $3 million contract this past winter to shore up the back end of the Tribe's bullpen, the 42-year-old Hernandez has had a disappointing first half, going 3-1 with a 6.23 ERA in 28 appearances.
Dellucci has also struggled this season in his role as the left fielder against right-handed pitching. He was batting .234 with four homers and 20 RBIs in 54 games before injuring his leg while running out a ground ball in the fourth inning of Tuesday's loss to the Phillies.
This is Dellucci's fifth career trip to the DL and his first since 2003. More information on his condition was expected to be announced by the club later Wednesday afternoon.
This will be Francisco's second call-up to the big-league club this season. He was batting .329 with six homers and 34 RBIs for the Bisons, ranking fourth in the International League in hits (79), tying for fifth in steals (15) and fifth in batting average.
In replacing the left-handed Dellucci, the Indians might have opted for the left-handed-hitting Shin-Soo Choo instead of Francisco, but Choo is currently on the Buffalo DL with inflammation in his left elbow.
Like Francisco, Mujica will be making his second appearance with the Indians this season. He has gone 0-1 with 11 saves and a 6.35 ERA in 22 games at Buffalo. While with the Tribe from May 7-22, he appeared in two games, giving up two runs over four innings of work.
