After cruising through five innings, Arizona Diamondbacks starting pitcher Luke Weaver was abruptly removed from Sunday’s matchup against the San Francisco Giants with right forearm tightness, according to the team.

Throwing just 1-run ball in five innings of action, Weaver faced Giants catcher Buster Posey in the top of the sixth inning. After working a 2-2 count, Posey reached base on a single.

But the base hit was the least of the D-backs’ worries as Weaver came out of his release stretching his right hand in discomfort.

A trainer was quickly out to access Weaver before the pitcher was pulled with what the team later classified as right forearm tightness.

He allowed just one earned run on six hits, while striking out six and walking two on 87 pitches as the D-backs earned the series sweep of the Giants.

Weaver’s record now sits at 4-3 in 2019 following Sunday’s 6-2 win, tied for second on the team.

T.J. McFarland came in to relieve Weaver.

It’s a tough sight to see as Weaver has been a vital piece to keeping Arizona’s starting rotation afloat.

Entering play Sunday, Weaver was second on the team in quality starts (six), just four behind ace Zack Greinke.
