Phillies closer Jonathan Papelbon sees a lot of himself in rookie right-hander Ken Giles.

Papelbon was once among the hardest-throwing relievers in baseball, averaging 13 strikeouts per nine innings for the 2007 World Series champion Boston Red Sox.

He’s operating more on experience than velocity these days, but Papelbon appreciates the buzz that Giles has created with his 100-mph. fastball.

“He really does look like a young version of me,” Papelbon said. “Instead of throwing a split, he throws a slider.”

Little has gone right for the Phillies this season, but at least Giles has created positive vibes.

Of course, in this season, nothing can be totally smooth: Giles hit a stumbling block recently in a 4-0 loss to Washington. Entering the game with a 0.87 ERA, he allowed three runs, two of which were earned, in just one-third of an inning.

“There is nothing I can do about it now,” Giles said afterward. “I just have to forget about it and move on.”

The Nationals had looked overmatched by Giles in a 10-4 loss to the Phillies as he struck out three in 1 1/3 innings of scoreless relief.

Giles entered that game with runners on the corners and two outs in the seventh inning, trying to protect a 7-4 lead.

He promptly ended the inning by striking out former Phillie Jayson Werth, who whiffed on a 100-mph fastball.

Giles said he didn’t look at the scoreboard to check the speed of his pitch.

“No, I was too pumped that I was able to get the job done to keep the lead for the team,” he said.

Washington made an adjustment. Werth had one of the key hits, a run-scoring double, on a 97-mph fastball.

“They learned from the past experience and I have to adjust my next outing,” Giles said.

Giles allowed a home run in his first outing, pitching one-third of an inning in the 7-3 win over San Diego on June 12. In his next 18 appearances, he had a 0.44 ERA.

An improved slider has helped him. According to PITCHf/x data, opponents are hitting .129 against his slider.

Papelbon said Giles has impressed him with his approach to the game.

“It’s hard to prepare every single day for a big-league game and what I have seen from him so far is that he goes about his business in a pretty good way,” Papelbon said.

Giles, who turned 24 this month, had never pitched above single-A Clearwater before this year. Last season, he had a 6.31 ERA for Clearwater but also was hampered by an oblique injury that twice sent him to the disabled list.

“It was frustrating last year,” Giles said of dealing with the injury. “I knew it was kind of a blessing in disguise and it gave me more time to work on mechanics and the mental game a little bit.”

He was a non-roster invitee to spring training and wowed the Phillies early on with his fastball and improved slider. He had a 2.08 ERA in 41/3 spring-training innings, with five strikeouts.

Giles began the season at double-A Reading, where he had a 1.20 ERA, 29 strikeouts, five walks and seven saves in 15 innings. At triple-A Lehigh Valley, he had a 2.63 ERA with nine strikeouts, eight walks and five saves in 13 2/3 innings.

Manager Ryne Sandberg likes Giles.

“He really seems to be mature with his aggressive approach and it shouldn’t be a problem,” Sandberg said.

The 6-foot-2, 205-pound Giles concedes that he didn’t envision such a rapid rise to the majors, but he hasn’t been overwhelmed by his new surroundings.

“I didn’t know if I would get here this quickly, but nothing is impossible,” he said.
