"Command. It's been command," said Red Sox manager John Farrell. "Is that a direct correlation to the innings workload to date? That's quite possible. I thought last night his velocity was consistent or similar to previous starts. The command from pitch to pitch was not there -- and it cost him. That's something we monitor close. He's going to start Friday at [St. Petersburg]. We continue on."
In truth, the Red Sox don't really have any other options with Steven Wright still shut down with bursitis in his right shoulder.
Pomeranz lasted 3 2/3 innings on Sunday against the Yankees, giving up seven hits and four runs. Five days earlier, he went two-plus innings in his start against the Orioles, allowing four hits and five runs.
For the season, Pomeranz is at 164 1/3 innings. His previous high was 146 2/3 in 2012, which included his totals in the Minors that year.
"I feel strong. I feel good. I'm just not making pitches when I need to," said Pomeranz.
In 12 starts since his trade to the Red Sox, Pomeranz is 2-5 with a 4.91 ERA. However, Pomeranz did have a solid seven-start run between Aug. 4-Sept. 5, when he posted a 2.76 ERA and allowed three earned runs or fewer each time out.
The Red Sox have their next off-day on Sept. 26. Perhaps after that, Farrell can build in some extra rest for Pomeranz.
"We're in a dogfight," said Farrell. "We're staying the course right now."
