RHP Felix Hernandez had another strong start but lost a pitching duel with the New York Yankees' Luis Severino on Thursday. Hernandez (5-4) allowed just one run -- a solo homer by Brett Gardner -- on three hits in seven innings. Hernandez struck out a season-high nine batters. "Felix was really sharp and gave us everything he had," Mariners manager Scott Servais said. "Unfortunately, the other guy was a little better."

RHP David Phelps was acquired from the Miami Marlins on Thursday in exchange for four prospects. The Marlins received CF Brayan Hernandez, the Mariners' No. 6 overall prospect according to MLB.com, and RHP Brandon Miller, Pablo Lopez and Lucas Schiraldi. The 30-year-old Phelps (2-4, 3.45 ERA) is in his first season as a full-time reliever after spending the first five seasons of his career as a starter. "David was a target player for us headed into the deadline period," Mariners general manager Jerry Dipoto said. "The quality of his work, particularly over the past two years in the bullpen, in addition to his versatility (including his background as starter) made him very attractive to us. He fits our roster very well and is controllable through the 2018 season." Phelps is making $4.6 million this season and is slated to be arbitration-eligible in 2018.

3B Eduardo Nunez committed a key baserunning gaffe when he overslid third base on a steal attempt in the sixth inning Thursday in a loss to the San Diego Padres. The mishap occurred after his first of two hits in the game had gotten the Giants even at 2-2. But on Ball 4 to 1B Brandon Belt, Nunez took off for third and easily beat the ball to the base, but he couldn't stop himself in time and was tagged for a critical second out in the inning. The Giants never scored again in the 5-2 loss.

LHP Madison Bumgarner gave up two home runs for a second consecutive game in a loss to the San Diego Padres. He had never surrendered multiple homers in back-to-back games in his career. The Giants have totaled 10 runs of offensive support in Bumgarner's six starts this season.

He is 7-3 with a 3.68 ERA in 14 career games, including 12 starts, against the Padres.

RF Hunter Renfroe (strained neck) was reinstated from the 10-day disabled list Thursday before the game against the San Francisco Giants.

RHP Trevor Cahill will attempt to duplicate last week's success against the San Francisco Giants when he makes a road start Friday night.

3B Todd Frazier, acquired Tuesday night from the Chicago White Sox, made his first start with the Yankees on Thursday and singled in the ninth inning.

For the record, Jeter had 3,465 hits.

LF Brett Gardner hit a solo home run off Seattle's Felix Hernandez in the sixth inning Thursday, breaking a scoreless tie as the Yankees went on to win 4-1. Gardner hit a 2-1 pitch from Hernandez into the right-field seats, a shot estimated at 406 feet. It was Gardner's 16th home run of the season. "He gave me a fastball and kind of left it in the middle," Gardner said. "You don't want to miss a pitch like that."

1B Chase Headley made his seventh career start at first base Thursday. Headley, who started six games there in 2014 for the Yankees, was switched from third base after New York acquired two-time All-Star Todd Frazier earlier in the week. "I think he's going to be just fine," Yankees manager Joe Girardi said of Headley. "He's got a pretty good idea what he needs to do. We've seen him there in spring training and from time to time. The only thing over there that's going to help him is experience."

RF Aaron Judge, who had been in a 3-for-28 slump since winning the Home Run Derby at the All-Star Game in Miami, had a clutch hit Thursday.

RHP Luis Severino (6-4) pitched seven scoreless innings Thursday to beat Seattle 4-1 in a matchup against longtime Mariners ace Felix Hernandez. Severino allowed eight hits but got out of several jams. He walked one and struck out six. "I knew it was going to be tough," Severino said of facing Hernandez. "That's who I compare myself to. Any chance you get to face a guy like that, it gives me a chance to (get) better."
