Felix Doubront came to camp out of shape, was shut down with a sore left shoulder and has been behind ever since. But yesterday he finally made his spring debut.

There’s little point in judging a pitcher on the results of his first spring appearance — for the record, the left-hander was lifted after a two-out walk in the second inning, having allowed two walks and a double with two strikeouts in the Red Sox’ 5-1 win in Grapefruit League play against the Tampa Bay Rays — but Doubront has left himself in a position to be judged by the way he came to camp.

The fifth starter’s spot in the Red Sox rotation is his for the taking, but Doubront will need to take it — it won’t be handed to him.

“I’ll start throwing more innings here and start facing more hitting and start gaining my confidence,” Doubront said. “I’m 100 percent confident, but I have to feel 100 percent ready to pitch. That’s what I’m doing now. I’m working hard every day to feel that way, and it starts today.”

Doubront’s pitches had some bite en route to the two strikeouts, but he labored with his command, throwing just 23 of his 43 pitches for strikes and working at a slow pace. He admitted feeling a little trepidation about the health of his shoulder.

“Every pitch, I was focused more and was a little bit scared to feel something,” Doubront said. “(But) everything went well. Tomorrow’s another day. I have to just figure out my mechanic and there was a big challenge for me to see how my shoulder was.”

Doubront’s looking forward to how he feels this morning.
