The U.S. men’s gymnastics team will compete in the Olympic team finals starting at 10 a.m. Beijing time Tuesday.

Former Oklahoma standout Jonathan Horton figures heavily into the Americans’ hopes. He will compete on five of the six apparatus, and with a three-up-three-count format, every score matters. Every gymnast who competes will have their score count toward the team’s final score.

No other American gymnast is competing on more events than Horton.

No gymnast, then, will be counted on more by Team USA than he will.

Here’s a look at the Americans’ lineup for the team finals:

Still rings: Raj Bhavsar, Jonathan Horton, Kevin Tan

Vault: Bhavsar, Horton, Justin Spring

Parallel bars: Bhavsar, Horton, Spring

Horizontal bar: Joey Hagerty, Horton, Spring

Floor exercise: Spring, Hagerty, Horton

Pommel horse: Tan, Bhavsar, Alexander Artemev
