"It was good to be back," said Rodriguez, who was coming off five appearances with Triple-A Pawtucket spread over two rehab assignments. "Pitched pretty good and I located my pitches pretty good. My changeup was a great key tonight."
Rodriguez left after throwing 89 pitches, including 61 strikes. He didn't allow any walks and had three strikeouts.
"I wouldn't say he was gassed," said manager John Farrell. "It might not have had the same life in the last inning, but I wanted to get him out on a positive note. We had the lead, I felt like giving a clean inning to the bullpen and they did a fantastic job tonight. So I thought it was a good job for him tonight."
Rodriguez went 10-6 with a 4.07 ERA as a rookie last season and is expected to be a key cog in the rotation.
"It's a guy that we thought would be in the middle of the rotation from the start of the season," Farrell said, "so to have him join us now, this is almost like a Trade Deadline big acquisition for us. Provided he goes out and pitches to his capabilities, it certainly adds to our rotation."
While Rodriguez was sharp, Farrell said there is still room for improvement, specifically with the lefty's velocity.
"I thought it was solid," Boston's manager said. "We've seen better velocity before, but I thought he stayed away from the middle of the plate for the most part. He threw a lot of strikes, he forced them to swing the bat when he did get into a 3-2 count. He pitched very comfortably, it looked like tonight."
