There figure to be at least a few new faces in the clubhouse Sunday, with rosters set to expand to 28, but one addition wont be due to the Sept. 1 date. Manager Aaron Boone said after that Anthony Rizzo is finally set to return from the fractured right forearm he suffered on June 16. Boone said Rizzo would likely play in the series finale after speaking with the first baseman on Saturday. Anthony Rizzo is set to return for the Yankees. Corey Sipkin for the NY POST Hes good, Boone said. To make room for Rizzo, following Saturdays game. Explore More The first baseman slumped through most of the first two-plus months of the season even before he suffered the freak injury on the bases and he went just 2-for-11 with a homer in his Cal Quantrill Jersey short stint with Double-A Somerset. Boone said he was not really concerned with Rizzos numbers during his minor league rehab stint, especially after seeing him take live batting practice at the Stadium earlier in his recovery. He racked up a lot of volume the last few weeks, Boone said of the work Rizzo put in. Hes been bouncing back physically. DJ LeMahieu and Rice havent done much in Rizzos absence, and Oswaldo Cabrera got the start at first on Saturday. The Yankees hope Rizzo can provide more offense at first base. Bill Kostroun/New York Post As for the rest of the Sunday additions, Boone said the team would discu s its options following Saturdays game. The manager said Friday that the organizations top prospect, Ja son Dominguez, is in consideration to be called up.

The right-hander was scheduled to make another rehab appearance Friday for Double-A Somerset in his comeback from a lat strain, but suffered back spasms prior to the game and was scratched. Boone said it didnt seem like a major thing. Scott Effro s, Nick Burdi, Lou Trivino and Ron Marinaccio are potential options. The team also hasnt determined Clarke Schmidts next step, as the right-hander could start for the Yankees on Monday in Texas or make another minor league rehab start on Tuesday, according to the manager. Boone said Schmidt was lined up to pitch a rehab game which would be Tuesday, since the minor leagues dont play Monday, and Boone added he would lean that way. In part, thats due to the fact Schmidt isnt fully built up as a starter, but he wouldnt rule out Schmidt going up against the Rangers. And with Schmidt taking Will Warrens spot in the rotation and Luis Gil back soon from a back strain, Boone said the Yankees would not nece sarily go with a six-man rotation. We still have days off, Boone said of the schedule. I wouldnt rule out anything. Im not committed to anything quite yet. Will Warren struggled on Saturday. Robert Sabo for NY Post Warren has allowed 24 runs in his first five outings.
