CLEVELAND -- Prior to their game against the Indians, the Padres activated right-handed starter Trevor Cahill from the disabled list to start Tuesday's series opener at Progressive Field.
As a result of Cahill's return, infielder Chase d'Arnaud was designated for assignment to open a roster spot. Cahill -- who will make his eighth start of the season on Tuesday, and his first since May 13 -- has been sidelined for more than seven weeks after he was placed on the DL on May 17 with a right shoulder strain.
Cahill returns to the mound after making two rehab starts in the Minors. His first came on June 22 with Class A Advanced Lake Elsinore, in which he allowed four runs in 2 2/3 innings. His second was on June 28 with Triple-A El Paso, and he allowed two runs in three innings.
"I watched his Triple-A outing for El Paso," manager Andy Green said. "His curveball is how it's been all year. It was really, really good. It was biting. It was locating. It was buried when it should be buried. So he had that pitch. Fastball velo is probably a touch down. A lot of that has to do with rehab outings. ... I thought the life on his pitches was good. I thought he looked good."
Before going to the DL in May, Cahill was one of the Padres' best starters. In seven starts (41 1/3 innings), he posted a 3-2 record with a 3.27 ERA and 51 strikeouts. In his three starts before going on the DL, the right-hander had a 1.56 ERA with 21 strikeouts over 17 1/3 innings.

"He's been the best we've had, starting rotation perspective, up until the point in time he got hurt," Green said. "He was throwing the ball really well. Complete four-pitch mix. Don't know what you're getting in any count. Curveball played very effectively for him. Definitely it hurt having him out and missing this much time."
d'Arnaud played 22 games with San Diego, hitting .143 (7-for-49) with two doubles, a homer, three RBIs and five stolen bases. The infielder began the season with the Braves, before being waived in late April and getting claimed by the Red Sox. The Padres claimed d'Arnaud off waivers from Boston on May 22.
Green said that the play of shortstop Erick Aybar was a contributing factor to the decision to waive d'Arnaud.
"There was a time, not much more than a month ago, where it looked like Chase would start stealing some playing time from Erick," Green said. "And Erick's play responded really well."
Injury updates
• Green said that outfielder Travis Jankowski -- who is on the disabled list with a right foot fracture -- is slowly making progress with his injury.
"He's running," Green said. "I'm hoping he is nearing closer to play, The last medical report on him was that he was running and moving around better. But at this point in time, he's not playing baseball. He's hitting and doing some stuff off the tee, I believe."
• Last Wednesday, outfielder Alex Dickerson underwent successful surgery to repair a bulging disk in his lower back.
"Everything went as it should," Green said. "Now, it's just the road to recovery, which is about six months for his back surgery."
