Harper is making his first professional start at first base Friday as the Phillies take on the Guardians, Alex Coffey of The Philadelphia Inquirer reports.
Harper has been working out at first base for a while now and is finally ready to try his luck at the position in a game setting. If he proves capable of handling first base regularly, it opens up designated hitter for Kyle Schwarber and allows the Phillies to improve their defense in left field.
