SEATTLE (AP) — James Paxton struck out a major league-high 16 in seven dominant innings, but the Seattle bullpen blew a late lead and the Oakland Athletics rallied past the Mariners 3-2 Wednesday night.

Paxton was overpowering in arguably the finest performance of his career, posting the highest strikeout total by a Seattle pitcher since Randy Johnson fanned 19 on Aug. 8, 1997. He got 14 A’s on swinging strikeouts.

Paxton left with a 2-0 lead. Jed Lowrie hit a two-run homer off Juan Nicasio in the eighth inning, then Mark Canha opened the ninth with a home run against Edwin Diaz (0-1). Diaz had allowed just one earned run in 15 appearances this season.

The left-handed Paxton was the fourth different pitcher in Mariners history to strike out at least 16 in a game, joining Johnson, Mike Moore and Mark Langston. Johnson struck out 19 twice, 18 once, and 16 twice in his Mariners career, while Moore and Langston reached the mark once.

But none of those other performances were as efficient as Paxton. He threw 80 strikes among his 105 pitches, gave up five hits and walked one.

Seattle went to Nicasio in the eighth and trouble arrived quickly. Pinch-hitter Matt Joyce lined a ground-rule double with one out and three pitches later Lowrie’s shot to nearly the same part of the yard had a little more elevation, clipping the top of the fence and bounding over. Canha’s homer was his fifth of the season and came on the second pitch of the ninth inning.

Seattle led 2-0 after Ryon Healy’s solo homer and Jean Segura’s RBI single in the third inning. But Seattle never padded the lead and missed chances with the bases loaded in both the eighth and ninth innings.

In both innings Seattle benefited by replay, but couldn’t capitalize against Blake Treinen. Segura’s double and an intentional walk to Robinson Cano loaded the bases in the eighth, but Treinen (2-1) struck out Nelson Cruz and Mitch Haniger. In the ninth, a replay review deemed Dee Gordon safe with two outs to load the bases but Segura grounded out to end it.

BEST OF APRIL

A’s starter Sean Manaea was chosen the AL pitcher of the month and Diaz was picked as the AL reliever of the month for April. Manaea was 4-2 with a 1.03 ERA in the first month of the season and had the lowest opponents’ batting average (.134), on-base percentage (.178) and OPS (.400) in the majors. Diaz recorded an AL-high 11 saves in 11 attempts in the month and a 0.63 ERA.

ROSTER SHUFFLE

The A’s optioned reliever Emilio Pagan to Triple-A Nashville. Pagan had a 5.93 ERA in 12 appearances and had allowed four home runs. Melvin said the goal for Pagan is to work on his fastball location and throwing his breaking ball when behind in the count.

UP NEXT

Athletics: Manaea (4-2) makes his second start of the season against Seattle. Manaea allowed one run and two hits in seven innings in a win over the Mariners on April 15.

Mariners: Wade LeBlanc (0-0) makes his first start for Seattle. LeBlanc is taking the place of Erasmo Ramirez in the Mariners rotation. Ramirez was placed on the DL earlier this week.
