SEATTLE -- The Mariners’ bats were beginning to wake up on Sunday afternoon, Bryan Woo delivered a bounce-back performance and the defense had turned a wild double play to come within an out of getting out of a jam.

But things turned south very quickly at T-Mobile Park with one swing of the bat in the top of the sixth inning of Seattle’s 6-4 win over Houston in the finale of a three-game set.

With a runner on third and two outs, Yordan Alvarez laced a shot to center field. Mariners star Julio Rodríguez covered 89 feet to get within reaching distance, but couldn’t hang onto the ball, then crashed into the wall at full speed and stayed down, holding his right ankle. X-rays taken after the game were negative and he is slated to undergo an MRI exam.

Dylan Moore and Victor Robles immediately began waving for trainer Taylor Bennett and manager Scott Servais to come out, and after a delay, the two took Rodríguez out, though he walked off under his own power.

Ty France entered the game at first base and Luke Raley moved to right field, while Victor Robles shifted from right to center field.

Rodríguez, who’s hitting .375 in July with a 1.122 OPS, already has dealt with one injury scare on a play in the outfield this month, when he caught his thumb on the turf while stumbling to make a catch. He also left the Mariners’ July 6 game against the Blue Jays with right quad tightness, and didn’t start the following day.

The injury put a damper on what was otherwise the brightest day in a slow start to the second half for Seattle. After managing just two runs and seven hits in their first two games against Houston -- and falling out of first place in the AL West since May 11 – the Mariners broke out with five extra-base hits in the first six innings.

Dylan Moore opened the scoring with a two-run triple in the second inning, and Jorge Polanco and Raley both hit home runs.

Meanwhile, Woo struck out five in 5 2/3 innings in just his second July start, giving up two runs on four hits with zero walks.
