Oakland Athletics vs. Seattle Mariners Pick – MLB July 31, 2020

    Sean Manaea (0-1, 7.71 ERA) vs. Taijuan Walker (0-1, 13.50 ERA)

The Oakland Athletics and Seattle Mariners will get a four-game series started on Friday night in Seattle. All four games will be played in Seattle. There are plenty of home and homes during this shortened season, but the Mariners get all four games at T-Mobile Park. I will refer to T-Mobile Park as Safeco for the foreseeable future, though.

It can often take a minute to get used to the new name of a stadium. The Athletics are coming off a 5-1 loss against the Colorado Rockies on Wednesday at home in Oakland. Starting pitcher Frankie Montas gave the Athletics a chance to win, but the offense didn’t respond.

Montas went 5 innings with 5 hits and 2 earned runs conceded. Nothing wrong with that, but German Marquez was on point with 4 hits and 1 run conceded in 6 innings of work. With the Rockies going back home, we’ll see if they can handle Coors Field for the first time this season.

Meanwhile, the Athletics move on to Seattle for their second series of the year. The AL West has gotten off to a slow start, with the Athletics and Mariners tied up at 3-3. The Mariners have three wins as well, but have played one fewer game than the A’s and Mariners.

The Mariners are projected to be one of the worst teams in the major leagues, but who knows with only 60 games on the schedule. Anything could happen, and any team can get hot at the perfect time. Even if the Mariners get hot over the next week or two, though, they will probably fade away late.

They have an expanded playoff to look forward to, but it’s still going to require some breaks along the way to get in. The Mariners are expected to send out Taijuan Walker for the home opener at T-Mobile Arena. Sean Manaea, who looked tired in his performance against the Angels, will counter for the Athletics. Head below for our free Oakland Athletics vs. Seattle Mariners pick for July 31, 2020 in MLB.

Oakland Athletics vs. Seattle Mariners Prediction:

It was not the start that Sean Manaea envisioned to open the season. His arm looked tired and it showed with a poor performance against the Los Angeles Angels. While he was hitting his spots and his command was working well, Manaea wasn’t getting much on his pitches. The Angels were able to take advantage of the lapse, as they scored 4 earned runs in 4.2 innings.

This is an important season for Manaea. He pitched in just four games last season because of shoulder surgery. Manaea was expected to return soon after the All-Star Game, but his rehab kept dragging on. It wasn’t a good debut for Manaea, but he has an opportunity to respond on the road versus the Mariners.

Manaea should have the upper-hand on Taijuan Walker on the hill. Walker has pitched in just five games since the 2018 campaign. He’s been bothered by an injury as well. 2017 with the Diamondbacks is the most recent season that Walker got out of it having pitched a full season. Walker was good then, with an ERA of 3.49 and 1.33 WHIP.

However, Walker hasn’t been able to stay on the field since then, and he’s in the process of trying to work himself back into form. His 2020 debut didn’t go according to plan, as Walker was drilled for 7 hits and 5 earned runs in 3.1 innings for a 13.50 ERA and 2.40 WHIP against the Astros.

It’s been a long road back from Tommy John surgery for Walker, and it didn’t look like he was ready for the bright lights against the ‘Stros. Both Manaea and Walker have the potential to be good, but I think they need some more time to get the wheels greased up. At even money, I think the OVER is worth some consideration.
