Last season, after the coaches limited him to 5 innings in his first start, Ginn average 6 2/3 innings over his next five starts. Then LSU chased him after 5 innings in which he gave up 5 runs on 9 hits. He clearly was nowhere near as sharp as he had been. Then he left the Tennessee game after only 1 inning and it seemed pretty obvious he was having some arm problems, so they had to limit his pitches over the next few games.
This early in the season starting pitchers should be on a much lower pitch count limit than they will be later in the season. Plus, we have a bunch of new pitchers and the coaches need to see as many of them pitch in game situations as possible, so they can determine who they will be able to count on later. For the same reasons, some of the new guys will be left in these early games when the coaches would yank them in a league game later in the season. Bednar in the Saturday game is a great example. The coaches love his stuff and wanted to see him work out of jams in a game situation.
It is not so much about winning games right now as it is about getting a look at pitchers in addition to the weekend starters.
