"I'm happy with the way I played," Lowrie said after the Red Sox dropped a 6-4 decision to the host A's. "It felt good to be out there."
Lowrie, who began the season on the disabled list due to mononucleosis, was in the starting lineup at shortstop and batting second. He was 1-for-2 with a pair of walks, an RBI and a run scored. he also committed a throwing error.
"That was a good starting point: get on base and score the first run to get the team off to a good start," Lowrie said. "I'm going to continue to roll with it."
Lowrie batted .367 (11-for-30) in 10 rehab games between Single-A Lowell and Triple-A Pawtucket.
"I've had plenty of at bats on my rehab and I was ready to go," he said. "I had good reactions on the ball and my footwork was good. The one throw sailed on me. I was a little excited that (Rajai) Davis was running and I rushed the ball a little bit."
Lowrie has played for Boston in each of the past two seasons and delivered a key hit during the Red Sox's drive to the World Series in 2008.
"Offensively he did a good job," Boston manager Terry Francona said of Lowrie. "As he gets his legs under him, he will move a little bit better."
