PHOENIX -- The Padres are trying to determine the young arms who will be the building blocks of their future starting rotation. And on Sunday, right-hander Luis Perdomo continued to make a statement about being a part of that movement.
Perdomo has pitched six innings or better in his last 10 starts, dating back to July 22, despite losing this one to the D-backs, 3-2, at Chase Field.
He allowed five hits and all three runs on homers -- a pair by J.D Martinez and another off the bat of Paul Goldschmidt. That duo has combined to hit 71 this year, so there was no shame in that. Otherwise, Perdomo walked two, whiffed four and tossed 92 pitches.
"For me, the big thing right now is staying focused and worrying about my work," said Perdomo, who's 7-10 with a 4.61 ERA in 26 starts. "I'm trying to put myself in a good position so next year, whenever those decisions are made, I'm in a good spot. I have no control of that."
The Padres are currently in a six-man rotation, most of them older pitchers like Clayton Richard, Jhoulys Chacin, Jordan Lyles and Travis Wood. Richard, Lyles and Chacin are free agents at the end of the season and Wood is signed through 2018 with a club option for '19.
The Royals are paying Woods' $6.5 million contract for next season, so he's probably a keeper.
The future at the Major League level right now is Perdomo and 25-year-old right-hander Dinelson Lamet, who's 7-7 with a 4.32 ERA in 18 starts.
The Padres also have a deep six-man rotation at Double-A San Antonio, which is still in the playoffs. The big league organization is high on prospectsEnyel De Los Santos, Brett Kennedy, Michael Kelly and Cal Quantrill, to name a few.
Many clubs skip the Triple-A Pacific Coast League for development these days because it's so hard on pitching with teams in that league playing in high altitudes. Thus, don't be surprised if those kids are in camp next spring vying for spots in the Padres rotation.
"We're not afraid to bring any of them up from Double-A," Padres assistant general manager Josh Stein said Sunday.
Perdomo is 24 with a lot of upside potential. He is very coachable and said he's working mostly on keeping all of his pitches down and incorporating a changeup into the mix when he arrives in Peoria, Ariz., to join the club next February.
Padres manager Andy Green said they still haven't determined whether Perdomo is one of the staff building blocks.
"He's trying to pitch himself into that," Green said. "The message repetitively from us is, 'Let's get better, let's get better. There's more in there.' The elimination of a certain type of pitch. The execution of pitches that are great for him. I don't think anybody's done enough to say they're a building block for us.
"He's in contention to be a guy for us. And we like that, but the bar is higher and we need him to clear it."
