Biddle strains quad in return to Reading

SAN FRANCISCO -- Phillies pitching prospect Jesse Biddle strained his right quadriceps in Saturday's start with Double-A Reading.

"We don't think it's serious but I haven't heard anything about it today," Phillies general manager Ruben Amaro Jr. said of the team's No. 4-ranked prospect.

It was Biddle's first start with Reading since being placed on the inactive list earlier this season because he needed a mental break. He allowed four hits, two runs and four walks and struck out four in 3 2/3 innings before leaving the game.

"He was OK until then," Amaro said about the injury.

Even hobbled, Revere contending for batting title

SAN FRANCISCO -- Based on the grimaces on his face, Phillies center fielder Ben Revere is playing with plenty of pain these days.

His surgically repaired right ankle is causing him fits.

"I've been this far," Revere said following Sunday's 5-2 loss to the Giants at AT&T Park. "We've got 40 games or something like that, so I can manage that."

But can he manage a run at the National League batting title? Revere went 3-for-5 Sunday to raise his batting average to .314, which is second in the league to Colorado first baseman Justin Morneau's .323 average. Revere was hitting .270 with a .617 OPS (on-base plus slugging percentage) in 68 games through June 25, but has hit .376 with an .820 OPS in 45 games since. Revere has just one career home run, but his .371 slugging percentage is only two points lower than Ryan Howard's .373 and 36 points higher than Domonic Brown's .335.

Revere has the best batting average in baseball since June 25, eight points higher than Washington's Denard Span.

"A couple guys have said some stuff about that," Revere said about a batting title. "If I can, that would be a blessing. I'll be aiming down, but my focus is just go out there, take one game at a time and win a ballgame."

Revere would be the first Phillies player to win a batting title since Richie Ashburn in 1958.

"I'm trying to and everything," he said about feeling locked in at the plate. "I'm just doing the best I can to help this team win. That's all I'm focused on. It's been pretty fun, just seeing the ball and hitting the ball good. I'm focused on trying to get on base for the guys behind me."

Kendrick expresses regret for storming off field

SAN FRANCISCO -- Phillies right-hander Kyle Kendrick apologized to Ryne Sandberg early Sunday morning at AT&T Park for almost leaving the mound before his manager arrived during a pitching change in the sixth inning Saturday.

Kendrick stormed off the field and immediately into the Phillies clubhouse.

"I didn't want to come out of the game," Kendrick said. "I wasn't trying to show up Ryno or nothing. I didn't try to. That wasn't my intention. I was just upset. I wanted to get where nobody could see me as quickly as possible."

He also said he wasn't upset at teammates Chase Utley and Ryan Howard for letting a routine popup fall between them, which sparked an ugly inning in which the Phillies blew a four-run lead in a 6-5 loss.

"I didn't handle it right," Kendrick said. "That wasn't very professional of me."

Kendrick is 5-11 with a 4.90 ERA, which is the third-highest ERA out of 94 qualifying pitchers in baseball. He is a free agent after the season.

"Everything has just kind of been building up," Kendrick said. "It's been a tough year for us as a team and me personally. You've still got to keep fighting. But little stuff irritates you. ... When I'm pitching I don't really think about [free agency]. When I'm out there, I'm just focused on one pitch at a time. When I'm out there, no. It's definitely not on my mind. Maybe in between starts I think about it because -- shoot, I'm human. I have a family to provide for. I have two kids. So I think, where am I going to be? All that stuff."

Asked if he thinks he will be back with the Phillies, Kendrick said, "I don't know. I want to go where whoever wants me. That's where I want to go. If it's here, great. If they want me. You want to go somewhere where you're wanted. We'll see. I don't know."

Phillies happy to get Valentin from Dodgers

SAN FRANCISCO -- The Phillies hope Jesmuel Valentin is one of two quality players to join the organization following the Roberto Hernandez trade with the Dodgers.

The Phillies acquired him Saturday as the first player to be named in the deal. The Phillies have until the middle of next month to select the second player, which will come from a remaining pool of three players. Phillies general manager Ruben Amaro Jr. indicated they are leaning toward a pitcher.

"We have a pretty good idea of who we want but we're still waiting to make a decision right now," he said. "We'll check on some medical stuff. They're younger guys. For the situation we're in and the player we gave up, I think we did pretty well. Even if we had just this guy, we'd be happy with it."

Prospect acquired by Phillies

Jesmuel Valentin, 2B: The son of longtime big league shortstop Jose Valentin, Jesmuel signed with the Dodgers for $984,700 as a supplemental first-round pick in 2012. He struggled in his first taste of low Class A in 2013 but has performed much better at that level this year, hitting .280/.349/.430 with 24 steals in 108 games. A switch-hitter, he has a little pop but is more of a contact hitter who might fit into the No. 2 spot in a Major League lineup. Signed as a shortstop, Valentin became a full-time second baseman in mid-2013 and the move seems to have relaxed him. He has a solid arm but his fringy speed and quickness fit better at second base.

Top 20 Prospects: Phillies | Dodgers
-- Jim Callis

MLB.com ranked Valentin, who is the son of former big leaguer Jose Valentin, as the No. 13 prospect in the Dodgers' organization and places him 16th in the Phillies' system. Selected 51st overall as a supplemental pick in the 2012 First-Year Player Draft, Valentin was hitting .280 with 22 doubles, nine triples, seven home runs, 47 RBIs and a .779 OPS (on-base plus slugging percentage) in 108 games with Class A Great Lakes.

Valentin will report to Class A Advanced Clearwater.

"We like the kid," Amaro said. "He's got baseball acumen. He's advanced pretty quickly. He plays short and second; we'll probably have him play second base for us. Switch-hitter. Plays the game well. ... We're not sure if he's better from the right or from the left side. He doesn't have a whole lot of Minor League at-bats yet. But he's all right. He's someone who handles the bat pretty well. He has a little bit of pop. He's not a big guy, but has a little pop. He can run. He plays the game right. He plays hard."

Amaro said there is a chance the Phillies could make at least another trade before the Aug. 31 waiver Trade Deadline.

Worth noting

• Amaro wasn't happy with Saturday's sloppy defense in a 6-5 loss to the Giants. "It was terrible," he said. "Plain and simple, it was embarrassing. It happens. It shouldn't happen, but it happened."
