PHILADELPHIA -- Jake Diekman didn't need to watch the tape to know what he was doing wrong in Thursday's outing against the Cubs.
The Phillies rookie reliever knew his alignment toward home plate was off, but for whatever reason, he couldn't fix it on the fly.
Once he did cure the problem in the days after, the results were evident. In the eighth inning of Sunday's 5-1 loss to Boston, Diekman needed just 11 pitches to strike out the side. The strong performance came just three days after he allowed four runs in two-thirds of an inning in Chicago, making a five-run game come down to the wire.
Diekman then struck out four batters in 1 2/3 innings Tuesday in a 5-2 loss to the Nationals.
"I was just throwing way too far across my body where my arm was dragging, and I just couldn't throw it inside," Diekman said. "I was closing myself off too much and just leaving it right down the middle or way, way outside."
Diekman has appeared in four games since his promotion from Triple-A Lehigh Valley. In three games, he's pitched great. The other, not so much. The lefty is 1-0 (he got his first career win in his debut on May 15), but the poor outing caused his ERA to balloon. It now sits at 7.71.
"I learned from it," Diekman said. "I had to otherwise [or] I wouldn't be up here very long. So it made me refocus and really figure out what I was doing wrong and try to fix it."
Specialist confirms Worley has bone chip
PHILADELPHIA -- Phillies right-hander Vance Worley rejoined the team Tuesday after visiting orthopedist James Andrews on Monday in Florida.
Worley is on the disabled list with inflammation in his right elbow. He said he also has a bone chip, which the Phillies have described as a "small body that is embedded in the lining of his joint."
Worley wanted a second opinion before he resumed his throwing program, which could happen this week. He said Andrews confirmed the Phillies' diagnosis.
"Immediately after he just grabbed my arm he knew it wasn't Tommy John," he said. "That was good. Now I've just got to go out and get it going."
Asked if he is confident he can pitch with a bone chip in his elbow the remainder of the season, he said, "It doesn't feel good, but I can do it."
Outfielder Laynce Nix said his strained left calf will keep him on the disabled list longer than 15 days, though he will travel with the club to St. Louis. Nix is eligible to come off the disabled list Friday.
"It's kind of just a process of waiting and making sure it's 100 percent before I test it," Nix said.
Right-hander David Herndon (right elbow inflammation) received a platelet-rich plasma injection Tuesday by team physician Michael Ciccotti. He will be reevaluated in two weeks.
Right-hander Mike Stutes (right shoulder inflammation) will be shut down another 10-14 days. He then will be reevaluated to see if he can begin a throwing program.
Right-hander Justin De Fratus (sprained right elbow) will resume his throwing program Friday.
