Jason Bartlett and the Twins have agreed to push back his opt-out date to the end of this week. Bartlett could have opted out on Tuesday morning, but he's just 3-for-34 (.088) in the Grapefruit League and wouldn't have had much luck on the open market. The Twins will give him another few days to prove himself worthy of a roster spot. But the most likely scenario has him winding up at Triple-A Rochester to open the season.
