The Mariners lost for the third time in five games as word circulated that Encarnación could be on his way to New York. The 36-year-old slugger entered the day with 21 home runs in his first season with Seattle. If completed, the deal would be the latest indication that the last-place Mariners are looking toward the future after beginning the season 13-2. Seattle traded Jay Bruce to Philadelphia on June 2 and may be in line to make additional moves before next month's deadline.

Montas (9-2) was crisp in winning his fifth straight. He allowed two runs, six hits and walked one. He struck out cleanup hitter Daniel Vogelbach and Kyle Seager twice and struck out the side in the fourth. Montas had nine or more strikeouts for the fourth time in 14 starts.

Manager Scott Servais had plenty of time to contemplate the state of his ballclub after being ejected by home plate umpire Carlos Torres in the fourth inning. Seager was called out on strikes and was arguing with Torres when Servais intervened and was tossed.

It was a frustrating day all around for Seattle. The Mariners struck out 12 times and matched their season-high with four errors.
