• Dodgers Top 30 Prospects
Buehler, who had Tommy John surgery in 2015, has thrown 88 2/3 innings in the Minors this season, sporting a 3.35 ERA in 28 games with 125 strikeouts.
"He's had a very quick ascension," Roberts said of the 23-year-old Buehler. "He's ultra, ultra competitive and ultra talented."
Whether or not Buehler will get a spot on the Dodgers' playoff roster is still up in the air, but the Dodgers see his callup as an opportunity for Buehler to get some much-needed experience in the Majors and to help the club down the stretch.
"It all depends on how he fares," Roberts said about Buehler possibly making a postseason roster. "He's going to get opportunities, but when you're talking about the postseason, we're really not thinking about a postseason roster. I can honestly say that. We want to put eyes on him. He's earned it. To be around our guys, Kenley [Jansen], Clayton [Kershaw], Rich [Hill] and have Rick [Honeycutt] put eyes on him, this is a good thing for his development. He's going to get opportunities and like I say, every day is a test."
Seager starts throwing program
The Dodgers are planning to have their All-Star shortstop, Corey Seager, back in the starting the lineup during their upcoming series against the Rockies this weekend at Dodger Stadium. Roberts said there isn't a set date for the 2016 National League Rookie of the Year to return, but he is expected to make a start as long as he continues to progress from his elbow injury.
Seager has not started the last three games and has only appeared in pinch-hitting situations because he's had issues throwing.
The Dodgers called up shortstop Charlie Culberson from Triple-A OKC on Monday to start at shortstop and Seager is still available to be used in pinch-hit situations if needed. Seager took grounders on Monday and started a throwing program, which "went well," Roberts said.
"I think it was a positive day for him."
• Joc Pederson and Trayce Thompson will be recalled from Triple-A and will rejoin the team on Tuesday. The Dodgers also plan to recall Kyle Farmer after his 10-day option period is over.
• Righty Brandon McCarthy is still dealing with blister issues and was transferred to the 60-day disabled list retroactive to July 21. Roberts said McCarthy will make another Minor League start with Class A Rancho Cucamonga next week and the Dodgers will take the next step from there.
• Right-hander Josh Fields was reinstated from the 10-day DL after a back injury caused him to land on the DL.
• Yu Darvish donated $100,000 through the Texas Rangers Baseball Foundation toward Hurricane Harvey relief efforts.
