The Toronto Blue Jays filled out their starting rotation Wednesday, naming Scott Richmond their fifth starter.

Richmond beat out Brad Mills, who was tagged for five earned runs on 10 hits in five and one-third innings in his final spring training start on Tuesday night. He was subsequently sent to triple-A Las Vegas.

Entering the final week of spring training neither man had distinguished himself, but Mills's lacklustre performance against the Philadelphia Phillies convinced the team he needed more seasoning.

Mills, 24, doesn't disagree.

"Based on [Tuesday] and my last couple of outings I haven't been at my top game," he said. "What's the point of going [to the majors] if I'm not going to have success? I trust that when it happens, the timing will be right."

Richmond joins fellow righties Roy Halladay and Jesse Litsch along with left-handers David Purcey and Ricky Romero in the starting rotation.

Richmond made his final spring training start Wednesday against the Detroit Tigers without the burden of wondering whether he'll make the team.

He went 1-3 with a 4.00 earned-run average in five late-season starts with the Blue Jays last year.

Jays home opener April 6

The six-foot-five, 220-pound Richmond ended the campaign with Toronto, blanking the hometown Baltimore Orioles over six innings in a rain-shortened 3-0 win on Sept. 26 for his first major league victory.

In eight starts for Syracuse, Richmond went 1-3 with a 3.56 ERA.

He was on Canada's roster at the recent World Baseball Classic but never appeared in a game.

Richmond would have been Team Canada's No. 1 starter at the Beijing Olympics last summer, but the Blue Jays summoned him from triple-A Syracuse three days before the Olympic team finalized its roster.

The Blue Jays finalized their Opening Day roster Wednesday, with Michael Barrett being named backup catcher to Rod Barajas. Catcher Raul Chavez was sent to the club's minor league camp while utility player Joe Inglett was optioned to Las Vegas.

Inglett, who hit .190 and scored five runs, will remain on the team's 40-man roster.

His demotion leaves Kevin Millar, Jose Bautista and John McDonald on the Blue Jays bench.

Toronto opens the season April 6 against the visiting Tigers at 7:15 p.m. ET.
