San Diego Padres vs. Seattle Mariners MLB Pick – September 18, 2020

Probable Starters:

    Chris Paddack (3-4, 4.74 ERA) vs. Yusei Kikuchi (2-3, 5.35 ERA)

Note that this series was scheduled to take place in Seattle, but has been moved to San Diego because of the wildfires. While the Mariners are listed as the home team, this game will be played at Petco Park in beautiful San Diego. It’s really an unfortunate situation for the Mariners, but they had to sign off on this idea.

The Mariners are currently the first team out in the American League standings. While they’re the first team out, the Mariners aren’t exactly close, though. Seattle goes into Friday with a record of 22-28, and the last team in is the Blue Jays with a record of 26-23. With the regular season winding down, the Mariners are going to run out of time.

That said, anything can happen and maybe they have one last push in them. If the Mariners were closer to getting into the postseason, having to play in San Diego would be more frustrating. They are coming off three straight losses, including getting swept in a brief two-game interleague series against the Giants. The Giants were 9-3 and 6-4 winners the last two days to deal the Mariners with a crushing blow to their playoff hopes.

The Padres are going to the postseason, but their odds of winning the NL West are slipping away. The Dodgers own a four-game advantage on the Padres in the division, with the window slowly closing in San Diego. Win in October and that’s all that matters, though. It wouldn’t be too outlandish if the Padres reach the World Series. You can’t discount a team with Manny Machado and Fernando Tatis Jr. in the lineup.

Chris Paddack getting into elite form in October would do a lot for their chances. Mike Clevinger, Zach Davies, Dinelson Lamet, and Paddack pitching up to their full potential would be one impressive pitching staff to go into the postseason with. Paddack, though, hasn’t shown what he’s capable of so far this season. He will try to do so on Friday night at Petco, while Yusei Kikuchi is penciled in on the hill for the Mariners.

San Diego Padres vs. Seattle Mariners Prediction:

Yusei Kikuchi gets some bad luck having to pitch in San Diego on Friday night. Originally scheduled for Seattle, where Kikuchi has been much better, he will have to pitch on the road. This venue change has to be most frustrating for Kikuchi, who has posted an ERA of 4.03 and 0.94 WHIP at home.

Teams have been hitting just .194 versus Kikuchi in Seattle. Conversely, Kikuchi has been a different performer on the road. He boasts an ERA of 7.36 and 1.57 WHIP as a visiting hurler. That batting average goes all the way up to .316 for opposing teams.

Kikuchi hasn’t had too much fun against the Padres in previous matchups either. The Padres are hitting .433 with 2 home runs and 5 RBI against Kikuchi in 32 at-bats. Tatis Jr. and Machado are responsible for both home runs versus Kikuchi. I don’t think they’ll mind at all playing in San Diego over the weekend.

The Mariners’ offense is 22nd in the majors with 4.3 runs scored per contest. Chris Paddack is coming off extra rest with two more days rest after spraining his right ankle against the Giants. He pitched 2 innings before leaving the game with ankle discomfort. He reportedly feels good now and should be fine on Friday night.

Paddack will gladly welcome this surprise home start as well. He has recorded an ERA of 4.11 and 1.08 WHIP at home as opposed to a 5.79 ERA and 1.45 WHIP on the road. Don’t expect Paddack to be in perfect form in this one, but the offense should be able to carry for the load against Kikuchi if that isn’t the case. I like the Padres by more than a run at Petco Park in the first game of this four-game series in San Diego.
