The Athletics have struggled this season at the plate. Oakland has a .211 batting average, which is 30th in the league. The Athletics have posted an on base percentage of .273, which is also last in the MLB. Oakland has earned a .600 OPS, which is 30th in the league as well. The A’s have a BA of .209 against right handers.

Seattle has been better hitting the ball throughout this season. The Mariners have a batting average of .233, which is 25th in the MLB. Seattle has earned a .318 OBP, which is 13th in the league. The Mariners have put up an OPS of .698, which is 18th in the MLB this season. Seattle has hit .236 against righties on the season.

The Mariners have not been great at the plate on the season, but have the edge in this one. Seattle has hit well against the Athletics in previous meetings on the season. Oakland has scored nine runs in their last three games, but could not get the win. The Mariners have 11 runs over their last two games and will look to remain hot.

Pitching Preview

Adrian Martinez will likely get the start at pitcher for Oakland in this one. Martinez has started in only one game this season with a record of 1-0. He pitched five and a third innings, giving up four hits against the Detroit Tigers on May 10. Martinez will make his second career start and will look to build on that performance in this one.

I expect Logan Gilbert to get the nod on the mound for the Mariners on Thursday night. Gilbert has earned a record of 8-3 throughout his 15 starts this season. He has posted a 2.44 ERA and a WHIP of 1.094 in those games. Gilbert’s last start was against the Los Angeles Angels. He gave up nine hits and three runs through five and two thirds innings en route to the win.

Gilbert gives Seattle the edge on the mound in this one with his strong season, but Martinez will look for another strong start in his young career. The Mariners also have the edge in the bullpen. Seattle’s relievers have an ERA of 3.80, which is 15th in the league. The Athletics bullpen has combined for a 4.52 ERA, which is 26th in the MLB.

Pick Overview

These two teams have been struggling throughout this season and will look for a big win in this one. Seattle has been solid as of late and will look to continue to climb the standings at home. The Mariners have the edge on the mound and at the plate early in this one. If Seattle can step up early, I think they can dominate this game.

Bovada has the Mariners listed as a -230 against the money line in this one. This implies that Seattle will win this game around 69.7 percent of the time. I think that this line is accurate, but there is very little value in it. The Mariners are also listed at -1 ½ for -105. I think Seattle can dominate this one and cover the spread.
