ST. PETERSBURG, Fla. -- Joba Chamberlain threw a bullpen session before Wednesday's game and is scheduled to throw a simulated game -- a first in his rehab -- Friday morning.
He has surpassed expectations in his recovery from Tommy John surgery and a dislocated ankle, but he said he thought it was important for decision-makers such as Joe Girardi and pitching coach Larry Rothschild to see for themselves, which they have this week.

"These are the guys you want to see you," Chamberlain said. "They see there have been no ill effects, they see the recovery. It's one thing [for them] to hear it, it's another to see it."
By late next week, he could appear in a rehab game.
Meet the new guy
The Yankees claimed outfielder Darnell McDonald off waivers from the Red Sox. McDonald, 33, who hit .214 with two homers and nine RBIs in 38 games before being designated for assignment June 30, will join the team in Boston Friday. To make room on the 40-man roster, righthander Chris Schwinden, claimed off waivers from the Indians June 29, was designated for assignment.
Girardi said his plan is to stay in rotation for the four-game series against the Red Sox, which starts Friday night and includes a day-night doubleheader Saturday. Hiroki Kuroda will start the opener and Girardi said he was "leaning" toward starting Freddy Garcia in the first game of the doubleheader, followed by Phil Hughes. Ivan Nova will pitch the series finale Sunday night.
A new rule allows teams to add a player for a doubleheader -- up until three hours before the first game -- and although Girardi said a decision hadn't been made yet, he strongly hinted the choice will be Cory Wade, sent to the minors Monday . . . CC Sabathia (groin) is scheduled to throw a flat-ground session Friday and a full bullpen session Sunday . . . Girardi said David Aardsma, ahead of schedule in his rehab from Tommy John surgery before suffering a setback last week, will be evaluated by his surgeon, Lewis Yocum . . . Brett Gardner could start taking dry swings "in the next day or two," Girardi said.
