Jansen said his arm will be ready because he has been throwing since shortly after surgery to remove a benign grown on his left (landing) foot.
He said he didn't know when he would be ready for MLB action, but didn't argue with an estimate of the first half of May. He will need several bullpen sessions before he can face hitters, then a Minor League rehab assignment of several games before being activated.
He will also need to run enough to cover first base at full speed.
"Running comes at the end," he said. "But the spot is not bothering me at all."
