"It's very frustrating," Kazmir told reporters, including Bill Plunkett of the Orange County Register. "I kind of changed my delivery a bit and it seemed like the lower back never bounced back."
Kazmir lasted just 1 2/3 innings Sunday against the Royals, allowing five runs on five hits, two walks and two hit batters (not to mention a balk).
Kazmir worked out Wednesday in Tampa Bay, but manager Mike Scioscia said Kazmir started complaining about his back tightening up.
"We'll push him back and give him a few days for this to calm down," Scioscia said.
Palmer struggled this spring with bronchitis, but pitched well at the end of spring training. He was 11-2 with a 3.93 ERA in 2009 before a shoulder sprain hindered his performance in Triple-A and with the Angels in 2010.
