SAN DIEGO >> Their names are spoken so often in the same breath, it’s strange to see Corey Seager and Julio Urias having such different Septembers.

The Dodgers’ two top prospects began the season as teammates in Double-A. Seager was promoted quickly to Triple-A Oklahoma City, then to Los Angeles on Thursday, and has applied his sweet left-handed stroke to major league pitching with preternatural ease.

Urias hasn’t risen as quickly. He had a solid 2.77 earned-run average in 13 starts for Double-A Tulsa, but has looked vulnerable since he was promoted to Triple-A. In two starts Urias has retired 13 batters, allowed 11 hits and nine runs.

“I don’t know if it was nerves or whatever, he just didn’t have his command,” Seager said of Urias’ Triple-A debut, in which he walked four batters in only one inning Aug. 31. “He really battled through it. His command just wasn’t there.”

In spite of his recent performance, Urias’ name came up again as a possible September call-up in manager Don Mattingly’s pregame media session. When discussing a 19-year-old left-hander with a mid-to-upper 90s fastball, and a changeup and curveball that make scouts drool, heavy hype dies hard.

Dodgers executive Josh Byrnes told the team’s radio station Sunday that Urias “probably won’t” be called up to the majors before the end of the season “unless circumstances dictate.”

Mattingly was even more tepid in his evaluation.

“We all kind of jumped the gun with this kid,” the manager said. “If something were to happen I guess he could be in the picture.”

Seager, for one, remains in awe. Despite being younger than any hitter he faced in Double-A, Urias’ opponents were overmatched.

“His command was unbelievable,” Seager said. “He threw it where he needed to at all times and his changeup was really working for him. People were missing by two feet. He threw it 20, 30 percent of the time and literally people couldn’t hit it.”

It was enough to make even a 21-year-old rookie feel old.

“He should” make me feel old, Seager said, “but he’s like a peer to me. He’s one of those guys that fits right in. Knows how to go about his stuff and does it.”

Nothing in Seager’s scouting report suggests that fans should contain their anticipation over Urias – even if the Dodgers decide he must wait until 2016.

That’s OK, Seager said.

“They should be (excited). He’s coming and it’s going to be impressive.”

Kendrick update

Howie Kendrick will join the Dodgers in Anaheim for the first of three games against the Angels, but he won’t be activated from the disabled list just yet. The second baseman hasn’t played since he strained his left hamstring Aug. 9.

“He’s at a point now that he’s close enough to be able to do some work on the field, get work with Stan (Conte, the Dodgers’ medical director) and our trainers here,” Mattingly said.

Kendrick could get into a game by the end of this week, but Mattingly said “I’m not sure if that’s going to be with us or someone else.” Oklahoma City will play its first Pacific Coast League playoff game Wednesday.

Kendrick attempted to run at full speed Saturday in Arizona and still has a ways to go.

“I think (running) the curves are still a little bit of an issue,” Mattingly said. “Straight-on, I think he was 100 percent. Felt like he could totally run. Had a little bit when he makes that turn, so that’s the last little bit we’ve got to get to.”

Both players have spent five separate stints in the majors. … Jose Peraza (left hamstring) is one or two days away from being able to rejoin the lineup, Mattingly said. … Justin Turner is expected to get his seventh start of the season at first base Monday, with Adrian Gonzalez serving as the Dodgers’ designated hitter. … The pitching matchups for the three-game series between the Dodgers and Angels: Zack Greinke will face right-hander Nick Tropeano on Monday; Clayton Kershaw will face left-hander Andrew Heaney on Tuesday; either Mike Bolsinger or Mat Latos will face right-hander Garrett Richards on Wednesday.

Julio Urias has worked almost exclusively as a starter during his brief professional career with the Dodgers, but some view him as a candidate to pitch out of the bullpen if he’s ever going to pitch for the Dodgers this season. Could Urias do it? After seeing him pitch in Double-A and Triple-A this season, Corey Seager thinks so.

“I think he’d have to like almost learn the mindset, learn how to do it,” Seager said. “His stuff’s so good. He can throw all three pitches. In the bullpen you only need one or two. I think he could learn the role. I think he’d be really good at it. He could let it fly, throw 95-plus, because in starts he really doesn’t need to. It could really translate.”
