Hartenstein chipped in 17 points (8-14 FG, 1-1 FT), 10 rebounds and four assists over 32 minutes during Monday's 130-109 win over Sacramento.
Hartenstein came off the bench in his season debut and needed only one appearance before moving into the starting unit, posting another double-double just like he did in his campaign opener. Hartenstein is expected to anchor things down low for the Thunder and should have an excellent two-way upside as long as he remains in a starting role.
