Yonder Alonso would be happy to return to the Mariners as a free agent this winter.
"I love it here," Alonso said. "It's awesome, a first-class group, and they treated me well. I'd love to be back here. I think the future here is very bright, and we're very close to winning, and I would definitely want to be a part of that." The Mariners figure to have some interest in keeping him, but it'll depend on what kind of offers he gets. He'll be an interesting case, as he's typically been a below average regular apart from the first half of this season. Oct 12 - 5:58 PM

Yonder Alonso finished 2-for-4 with a solo home run in Saturday's road victory against the Angels.

Alonso smacked his 28th homer while driving in his 67th run. It has been an amazing breakout season for Alonso at the age of 30 after he managed just 39 homers through his first 664 major league games over parts of seven years in the majors.
Oct 1 - 3:08 AM

Yonder Alonso is out of the Mariners' starting lineup Wednesday afternoon against the Athletics.

Alonso bombed his former team with a two-run homer and two runs scored in Tuesday night's 6-3 victory, but he'll grab some rest during Wednesday's matinee. Dan Vogelbach is starting at first base and batting sixth versus A's right-hander Kendall Graveman.
Sep 27 - 1:39 PM

Yonder Alonso went 2-for-3 with a two-run home run and two runs scored in Tuesday's 6-3 victory against the Athletics, his former team.

The All-Star Alonso is wrapping up a breakout season. He is up to 27 home runs with 66 RBI while slashing a respectable .265/.364/.497. His overall average is right in line with his career numbers, but he was a late bloomer in terms of his power production. Alonso entered 2017 with just 39 home runs through his first 664 major league games over parts of seven seasons before his breakout performance this year.
Sep 27 - 3:03 AM

Yonder Alonso went 2-for-4 and homered against his former A's teammates in Monday's win.

It's just Alonso's fourth homer for the Mariners after he hit 22 in Oakland. He's batting .252 with 15 RBI in 123 at-bats and 38 games for his new club. Obviously, that's not what the Mariners were hoping for from him, but given the way the rest of the team has played, they weren't going to the postseason even if Alonso kept up his All-Star pace.

Yonder Alonso went 3-for-4 with three RBI and a stolen base in Thursday's win over the Rangers.

All of Alonso's RBI came on one swing, as he roped an Andrew Cashner breaking ball into the right field corner in the fifth inning for a three-run double. It was his first three-hit game since August 21. The 30-year-old has cooled from his early-season pace but is still enjoying a nice season ahead of free agency, batting .269/.369/.501 with 25 homers, 63 RBI and 67 runs scored between the A's and M's. It will be interesting to see how he's viewed on the open market this winter.
Sep 15 - 2:17 AM

Yonder Alonso took Aroldis Chapman deep in the 11th inning to lead the Mariners to a 2-1 victory over the Yankees.

It was a solo shot. Alonso, who entered the game as a pinch-hitter, is just the third left-hander batter to ever homer off Chapman. Luke Scott was the first, but Alonso and Rafael Devers have both been in the past couple of weeks. Alonso is batting .302 with two homers and nine RBI over 15 games since being traded to the Mariners.
Aug 26 - 12:07 AM

Yonder Alonso finished 3-for-5 with three RBI and two runs scored in Monday’s win over the Braves.

Alonso played two runs with a double in the fourth inning and doubled home another run in the sixth. He’s now batting .318 (14-for-44) through his first 12 games with Seattle.
Aug 21 - 11:22 PM

Yonder Alonso is batting second Tuesday in his Mariners debut against the Athletics.

The first baseman was acquired from Oakland on Sunday for outfielder Boog Powell. Alonso boasts an .896 OPS with 22 home runs in 100 games this season, though he fell into a slump over his final few weeks with the Athletics. He's scheduled to become a free agent in November.
Aug 8 - 6:34 PM

Mariners acquired 1B Yonder Alonso from the Athletics in exchange for OF Boog Powell.

The M's claimed Alonso on revocable waivers and the two sides were able to work out a trade. Alonso has had a breakout season from a power perspective with 22 home runs, although just six of those longballs have come over his last 54 games. Still, Alonso should be an upgrade for Seattle at first base against right-handed pitching. Danny Valencia now figures to be on the short side of a platoon.
Aug 6 - 1:10 PM

Yonder Alonso is not in the Athletics' lineup Thursday against the Giants.

He's sitting against left-hander Ty Blach. Ryon Healy will spell Alonso at first base in Thursday's series finale. Alonso belted 20 homers in the first half but has only gone deep twice in 58 at-bats since the All-Star break.
Aug 3 - 6:37 PM

Yonder Alonso connected for a solo walk-off home run in the 12th inning of Sunday's 6-5, 12-inning win over the Twins.

The Twins held a 5-0 lead early on, but Oakland would come fighting back with two runs in the fourth inning, one in the fifth and two in the eighth to knot up the score and set up Alonso for his later dramatics. Stepping to the plate with one out in the bottom of the 12th inning, the first baseman let for fly for a walk-off solo shot to right against Tyler Duffey. He finished his day's work having collected three hits in five-at bats, including an RBI double in addition to his home run theatrics. A potential candidate to move at the deadline, Alonso is slashing .263/.364/.535 with 22 homers and 48 RBI over the course of 95 games played.
Jul 30 - 8:40 PM

Yonder Alonso is not in the Athletics' starting lineup for Fridays' showdown against the Twins.

Ryon Healy is starting in his place at first base while Alonso takes a seat against left-hander Jaime Garcia. He should be back in there on Saturday.
Jul 28 - 6:42 PM

Yonder Alonso went 2-for-4 during Wednesday's loss to the Blue Jays.

He singled and doubled in the ballgame but didn't factor into the scoring. He also struck out twice. The Athletics managed only one other hit in the ballgame. He is still having an excellent season despite a rough month of July. He is batting .267/.364/.534 with 21 home runs and 45 RBI.
Jul 26 - 10:28 PM

Yonder Alonso is not in the Athletics' lineup Friday.

He's getting a breather with the Mets throwing lefty Steven Matz. Jed Lowrie is also sitting out, as the A's have Ryon Healy at first base and Adam Rosales at second. Daily Slant: Steven Matz may appear to be a pitcher to avoid at first glance, but he's clearly still working his way back into form. Matz's velocity is down about a mile per hour this season and his strikeout rate has plummeted to 13.5% against right-handed bats and 19.1 against lefties. The A's lose the DH in an NL park and aren't one of the top stacks of the day, but targeting them for value - namely with Marcus Semien, Rajai Davis, Matt Chapman and Ryon Healy - is certainly viable.
