James Shields can't seem to catch a break so far this season.
While the Royals right-hander has tossed quality starts in six of his seven outings, he's managed to win only two of those games. Much of that can be attributed to the fact that Shields has faced a former All-Star in six of those seven starts.
He'll face another All-Star on Saturday in Andy Pettitte as the Yankees and Royals face off at Kauffman Stadium.
"Whenever the Yankees come in, they've got a good team," Shields said. "You've just got to go out there and pitch your game and hope that you win."
Shields had his best start of the season on Monday against the White Sox, allowing just two hits in eight scoreless innings. However, he took the no-decision in a 2-1 Royals loss in 11 innings.
Meanwhile, Pettitte will look to get back on track after two rough starts. After four straight quality starts to open the season, Pettitte is 0-1 in his last two games with a 9.64 ERA.
The 40-year-old southpaw yielded four runs (three earned) on four hits and four walks in five innings on Sunday.
Pettitte has especially had trouble with his cutter of late. The left-hander said earlier this season he had the best cutter he could remember in years. Now, he's wondering where the pitch has gone.
"It's going sideways," Pettitte said. "Last time [9-1 Yankees loss to Houston], it was backing up. I love the battle, I would just like to have a little bit of an idea where the ball is going.
"Everything has been great in my [bullpen sessions]. But something is going on in the games. I can feel my release point floating around. You just know from the feel of your fingers, the ball is just not coming off right. It has been a long time since I haven't had a feel for my pitches."
Yankees: CC may pitch in Monday's twin bill
After a conversation with pitching coach Larry Rothschild, Yankees manager Joe Girardi said on Friday that he is considering having CC Sabathia start one of Monday's doubleheader games in Cleveland.
Sabathia threw just 51 pitches over four innings before being knocked out by a rain delay in Thursday's 3-1 win over the Rockies at Coors Field.
"That would not be what I would want to do, but you never know what will happen this weekend and what we will need," Girardi said. "I can't say I'll do it, but a lot of it has to do with what we have to do this weekend."
Girardi also floated Ivan Nova's name as a possible starter for Monday, and Adam Warren is also a candidate.
Royals: Herrera finding way
Reliever Kelvin Herrera is back on track after serving up six home runs in his first 15 games.
In his seventh game on April 16 at Atlanta, he gave up three home runs. He bounced back with a scoreless inning the next day, but then on April 20 at Boston, he surrendered a game-deciding three-run blast.
Things have improved since then, with the exception of a loss to Chicago last Monday on a home run. He looked sharp in a scoreless inning on Thursday at Baltimore.
"I feel like new," he said. "I just feel like I'm going to strike out those guys. I have a feeling of confidence."
• Yankees shortstop Eduardo Nunez (sore left rib cage) swung in the batting cages on Friday and is hopeful that he will be able to play in Saturday's game.
• Royals catchers Salvador Perez and George Kottaras celebrated their birthdays on Friday. Perez turned 23, while Kottaras turned 30.
