The organization is going to keep a careful watch on the rookie hurlers.
Ideally, the organization is eyeing its first-year starters to log between 180-200 innings for the season.
Olsen has logged 126 2/3 innings, with Johnson at 120 2/3 and Nolasco at 109 1/3. Sanchez's situation is slightly different. Before being called up in late June, the right-hander threw 85 2/3 innings at Double-A Carolina. He now has 52 1/3 innings with the Marlins, giving him 138 total innings.
In the case of Sanchez, work is work, it doesn't matter where the innings were logged: Majors, Minors, it makes no difference.
According to the analysis of Lee Sinins and Will Carroll at Baseball Prospectus:
None of the Marlins rookie starters have reached the 175-inning threshold in their careers.
As prospects in 2005, Nolasco compiled 161 2/3 innings, compared to 152 for Johnson and 100 2/3 for Olsen. Of Johnson's total, 12 1/3 were in September as a callup for the Marlins. Olsen had 20 1/3 innings with the Marlins before being injured last July.
I truly hope the team will watch their progress with a concerned eye and err to the side of caution. When they pass 150-innings it is time to keep an extremely close watch on the starters. If mechanics breakdown or velocity drops off, fatigue may have set-in and injuries may not be far behind
The young Marlins starters are gold and keeping them healthy is where Kranitz is going to earn his money down the stretch.
