TORONTO -- The Boston Red Sox are expected to formally announce the David Price signing on Friday. The free-agent left-hander, who spent the second half of the season with the Toronto Blue Jays, has reportedly agreed to a seven-year deal worth US$217 million.

Here's a look at some star pitchers who played for the Blue Jays before leaving the team:

DAVID PRICE

Price came as advertised after he was acquired by former general manager Alex Anthopoulos in a blockbuster deal with the Detroit Tigers at last summer's trade deadline.

He provided the starting rotation with a true ace and delivered clutch performances down the stretch to help the Blue Jays end their 22-year post-season drought.

Price, who finished second in American League Cy Young Award voting, was 18-5 with a 2.45 earned-run average with Detroit and Toronto. However, he struggled in the playoffs with a 1-2 mark and 6.17 ERA.

The Boston Red Sox opened their wallet in a big way to land the star free agent, who will be 37 when his contract expires in 2022.

ROY HALLADAY

A face of the franchise for most of his 12-year run in Toronto, Halladay was dealt to the Philadelphia Phillies in December 2009.

Halladay won the 2003 American League Cy Young Award and was a six-time all-star with the Blue Jays. But with free agency approaching after the 2010 campaign and the franchise looking to the future, Halladay was traded in a four-team, nine-player blockbuster.

The Blue Jays acquired Kyle Drabek, Brett Wallace and Travis d'Arnaud in the deal.

Halladay, meanwhile, got to play for a contender as the Phillies were playoff regulars at the time. He spent four years in Philadelphia before retiring.

ROGER CLEMENS

Clemens signed with Toronto as a free agent in December 1996 and won back-to-back Cy Young Awards over the next two seasons.

After Toronto finished 26 games behind first-place New York in the East Division standings in 1998, "The Rocket" was dealt to the Yankees in the off-season for David Wells, Graeme Lloyd and Homer Bush.

Clemens, who was 36 at the time, played five seasons in the Big Apple before a three-year run in Houston.

He capped his career by returning to New York for the 2007 season.

CHRIS CARPENTER

Although he showed flashes of brilliance over six seasons ('97-'02) with the Blue Jays, Carpenter's injury woes were a regular concern.

He was limited to just 13 starts in 2002 and didn't play in the major leagues in 2003 due to shoulder problems. The St. Louis Cardinals took a chance on Carpenter in 2004 and he came through with a 15-5 record and 3.41 earned-run average.

Carpenter eventually blossomed into the starter the Blue Jays had hoped he'd become when they selected him with the 15th overall pick in the 1993 draft.

He would continue to shine with the Cardinals, taking the National League Cy Young Award in 2005 and helping the team win World Series titles in 2006 and '11.

DAVID CONE

Cone joined the Blue Jays in August 1992 and helped the team win its first World Series title that fall.

He wasn't around for the repeat victory the following year after joining the Kansas City Royals. Cone spent two years in KC -- winning a Cy Young in 1994 -- before returning to Toronto in 1995.

His second stint with the Blue Jays lasted just a little longer than his first.

With Toronto stuck in last place in the East Division, Cone was shipped to New York midway through the '95 season.

He maintained his strong form over parts of six seasons with the Yankees, earning a pair of all-star selections and winning four World Series titles.
