Martin has tweaked his pitching staff for the second time in three days as the Seminoles prepare for this weekend's important series at Clemson.
On Monday, Martin announced that Cannon would move to the bullpen as well as Rhett James, considered the team's most reliable pitcher who made a start against Georgia Tech last weekend.
In this latest move, Hunter Jones will open the series at Clemson on Saturday. Jones, who opened the season as the Seminoles' ace, was used in relief against the Yellow Jackets.
Cannon, who suffered three defeats and had a no-decision in the No. 1 spot, will start Monday's final game against the Tigers.
Sunday's second game belongs to freshman Brian Schultz, who boasts a 2.73 ERA, second on the team.
Martin's latest decision means Mark Sauls, who allowed nine runs on seven hits in 3.1 innings against Georgia Tech, moves to the bullpen. Sauls' latest struggles have been pinpointed to mechanics.
With 16 losses and two difficult road trips remaining against Clemson and Virginia, FSU could lost 20 regular-season games for the first time since 1985.
