DUNEDIN, Fla. — Marcus Stroman tossed 42/3 innings of three-hit ball and the Toronto Blue Jays beat the Boston Red Sox 2-1 in 10 innings Friday.

The right-hander allowed singles in the second, third and fifth innings to Allen Craig, Mookie Betts and Rusney Castillo, respectively. He also struck out four on 55 pitches before being lifted with two outs in the fifth.

“I want to go as deep as I can each and every game (and) put the boys in position to win,” Stroman said. “I’m looking to go nine a lot this year, and anything I can to keep that efficiency up and to keep my pitch count low, I’m going to do.”

Stroman is expected to fill the void atop Toronto’s rotation following the departure of David Price.

He missed nearly six months last season recovering from a torn anterior cruciate ligament in his left knee before returning for four starts in late September, going 4-0 with a 1.67 ERA.

Thursday marked one year since Stroman sustained the injury during a fielding drill last spring training.

Boston prospect Sam Travis homered to center field with two outs in the ninth.

Toronto prospect Jon Berti drove in the winning run in the 10th on a single to center.

ATHLETICS: Twelve pitches into his comeback attempt, Oakland’s Jarrod Parker broke his right elbow once again.

The 27-year-old, selected by Arizona in the first round of the 2007 amateur draft, has not pitched in the majors since the 2013 AL Division Series.

He had Tommy John surgery on Oct. 28, 2009, and again on March 24, 2014. He first broke his elbow on May 8 last year while pitching for Triple-A Nashville during an injury rehabilitation assignment.

Parker has a 25-16 record in parts of three seasons and once went a team-record 19 straight games without a loss.

BLUE JAYS: Left-hander Randy Choate agreed to a minor league contract and will report to big league spring training.

The 40-year-old reliever was 1-0 with a 3.95 ERA in 71 games over 271/3 innings last season for St. Louis.

PIRATES: Former All-Star infielder David Freese agreed to a $3 million, one-year contract.

The 32-year-old has a .276 career average with 68 homers and 348 RBI for St. Louis (2009-13) and the Angels (2014-15).

METS: Former closer Jenrry Mejia wants to challenge the agreement he made not to appeal his third positive drug test, which led to a lifetime ban from baseball.

Mejia accused MLB of orchestrating his third positive test because he refused to implicate another individual.
