TORONTO -- Buck Martinez, who was hired as manager of the Toronto Blue Jays without any coaching experience on the minor or major league level, was fired Monday in his second season.

Who is Carlos Tosca?

In his first year as Toronto's third-base coach, the 48-year-old Tosca has managed 17 seasons in the minor leagues and spent three seasons as Buck Showalter's bench coach with the Arizona Diamondbacks. Tosca, who has interviewed for several managing jobs in the past, spent 2001 managing Atlanta's Triple-A team in Richmond. In his minor-league managing career, he compiled a record of 932-827 (.530) and made the playoffs five times. He began his career in the Yankees' organization and also worked for the Royals and Marlins before joining the Diamondbacks in 1998. Tosca is known as a manager who isn't afraid to get in players' faces. Many felt the Jays had tuned out Martinez and Tosca is likely to bring a more fiery approach to motivate players. A native of Cuba, Tosca never played professional baseball.

The Blue Jays, off to their worst start in two decades, made third base coach Carlos Tosca the manager for the rest of the season. Toronto won its first game under Tosaca, beating Tampa Bay 6-1.

Toronto general manager J.P. Ricciardi said Martinez, who went to the Blue Jays bench before last season directly from the broadcast booth, was fired because of his lack of experience and leadership.

''I don't know if Buck even knows what his philosophy or style is because he hasn't had a lot of time to manage,'' Ricciardi said. ''It's not so much the wins, the losses at this point, it's more the leadership.''

First base coach Garth Iorg was also fired. Bullpen catcher John Gibbons takes over for Iorg while Brian Butterfield, fired May 16 as manager of New York's Triple-A affiliate in Columbus, joins the Blue Jays as third base coach.

Martinez becomes the fifth manager fired since opening day. Detroit fired Phil Garner, Colorado replaced Buddy Bell, Kansas City dismissed Tony Muser and Milwaukee fired Davey Lopes.

The Blue Jays, third worst in the American League with a 20-33 record, swept a three-game weekend series with Detroit but that didn't stop Ricciardi from replacing Martinez.

According to the Elias Sports Bureau, Martinez was the first manager to be fired after winning his previous three games since the Angels let Doug Rader go in 1991.

Martinez's fate has been questioned since spring training when Ricciardi, who replaced the fired Gord Ash in the offseason, issued a virtual ultimatum for Martinez to produce a hardworking team or face dismissal.

Ricciardi said the team quit halfway through last season and if things went as they did last year a change would be made.

After the Blue Jays dropped to 8-20 at home following a 0-6 stand at SkyDome last week, Ricciardi said Martinez's status would be monitored series to series.

''I don't think he was surprised. He understood something was maybe coming,'' Ricciardi said.

Only Tampa Bay and Detroit in the AL, and Milwaukee in the NL, have worse records than the Blue Jays.

Martinez had a year remaining on the three-year deal he signed in November 2000 after leaving the broadcast booth.

''Let's face it, Buck has never managed anywhere outside the big leagues and it's a tough place to learn from,'' Ricciardi said in spring training.

Tosca, who was hired by Ricciardi in the offseason, has managed 1,759 games in the minors. He managed Atlanta's Triple-A affiliate in Richmond in 2001 and spent the three previous years as bench coach of the Arizona Diamondbacks. He has been a minor league manager with the New York Yankees and the Florida Marlins.

Ricciardi said Tosca has paid his dues despite having never played professional baseball.

Tosca held a team meeting after being hired. He said he would meet with each player this week.

''I have been known to be confrontational,'' Tosca said.

Tosca said he wants to see some leadership from his players.

''It's a clubhouse that needs to have some leadership come forward,'' Tosca said.

Rookie third baseman Eric Hinske agreed.

''We've got some guys that are quiet but lead by example,'' Hinske said. ''We need somebody to step up and say 'This is how it's got to be done.'''

First baseman Carlos Delgado, named a team captain when Tim Johnson managed the Blue Jays in 1998, said he wouldn't get in the face of his teammates. He said they just have to play better.

''We need some players to step up, especially the older guys,'' Delgado said.
