Perdomo, Lamet continue to develop

Bill Center, longtime sportswriter for U-T San Diego, is an employee of the Padres.
One of the biggest positives for the Padres since the All-Star break has been the rapid development of right-handed starting pitchers Luis Perdomo and Dinelson Lamet.
Rookie Lamet, 25, has a 2.49 ERA in his eight starts since July 23. In his two most recent outings, Lamet has allowed two runs on 10 hits and six walks with 15 strikeouts in 12 innings. He has allowed only two homers in his last 47 innings.
The 24-year-old Perdomo, a Rule 5 Draft pick in 2016, went six or more innings for the ninth straight start Monday afternoon against the Cardinals at Petco Park. Over his last three starts, Perdomo has allowed five runs on 21 hits and seven walks with 11 strikeouts in 18 innings for an ERA of 2.50. His ERA in his nine starts since July 22 is 4.12.
"Perdomo and Lamet have been pushed hard lately by [pitching coach] Darren Balsley," manager Andy Green said before Sunday's game. "I like that element ... fighting together to be a part of what we do in the future. The bar we're clearing right now is not good enough for us. We have to clear a higher bar if we're to be what we want to be."
Speaking specifically about Perdomo, who allowed two runs Sunday, Green said: "His fastball is playing really, really well. He'd been fighting to get the slider back, but it came out really good today. I think he's gotten better. I'm pleased with the way he steps back off the mound, rests himself and goes back to executing his pitches.
"For us, it's about execution with him. It's not about results. If he executes, he'll get results. If he chases results, he loses his execution and the results aren't what he wants or what we want. I think he's in a really good mental place."
Green also discussed the number of errors made by the Padres' infield behind Perdomo:
"I think Luis has the highest ground ball rate in the game. Sinker ballers are always going to have more errors made behind them than other pitchers because the ball is on the ground more. At the end of the year, if just going by simple mathematics, your expectation would be the most prolific ground ball pitchers would have the highest number of errors made behind them. It's something he's going to have to combat for the rest of his career."
Perdomo, who leads the Padres with 15 quality starts this season, became the first Padre to complete six innings in nine straight games since both Andrew Cashner and James Shields did it in 2015. He induced two double-play grounders Monday, giving him a National League-leading 26 on the season, which is one more than teammate Clayton Richard.
Noteworthy
• 1B Wil Myers was 2-for-4 against the Cardinals Monday. It was his third straight multi-hit game and Myers was 7-for-11 with a double, triple, three RBIs and two runs scored in the three games. Myers is 12-for-34 (.353) over his last nine games to raise his batting average to .241 from a season-low .232 coming off a run of 21 straight hitless at-bats. Monday was Myers' 30th multi-hit game of the season, one fewer than team-leader Manuel Margot.
• RF Jabari Blash's run of strikeouts in eight straight plate appearances ended in his final at-bat Sunday. Blash is in a 1-for-14 slump.
• The Padres are 5-3 over the last eight games, but all three losses have been by shutouts.
