The Mariners head to the All-Star break with a 39-55 record after losing eight of their last 10 games.
Narvaez, one of Seattle’s key additions this season, went 4-for-4 with two home runs and all four RBIs, while hiking his average to a team-leading .294. His 14 homers on the season breaks Mike Zunino’s club record of 13 home runs by the All-Star break for a catcher. The 14 homers in 76 games are two more than he totaled in 221 games over his previous three seasons in the Majors with the White Sox.
