GOODYEAR, Ariz. — Justin Upton hit a two-run homer, and the Arizona Diamondbacks roughed up right-hander Aaron Harang in his first spring training start on Tuesday, pulling away to a 10-4 victory over the Cincinnati Reds.

Upton got a six-year, $51.25 million deal — the second-largest in franchise history — last week. He singled home a run and had a two-run shot off Matt Maloney, who is competing for the Reds’ fifth starter role.

Harang, already named to start his fifth straight season opener, lasted only 1 1-3 innings. He gave up four hits, including three doubles, and walked one, allowing three runs overall. Harang is trying to shorten his delivery during spring training.
