Tigers vs Mariners Pick
Money Line Pick for Tigers vs. Mariners
- Detroit Tigers ML (4 Units)
The Tigers have won three of their last four games, while the Mariners have lost their last four games. Detroit has the edge here because they’ve hit the ball well against right-handers, and they’re going up against Castillo, who gave up seven runs in his last three home starts. He struggled in recent starts against the Tigers, giving up eight runs in his last three starts against them, so expect him to have a hard time slowing them down.
Seattle won’t be as successful offensively because they didn’t hit the ball well in recent games, and they’re likely going to be facing Skubal, who gave up five runs in his last three starts. He gave up seven runs in his last three road starts, and with Detroit’s bullpen playing well, expect them to keep Seattle’s offense in check. Take Detroit on the money line.
Over/Under Pick for Tigers vs. Mariners
- Under (4 Units)
The Tigers played under the total in four of their last six games, while the Mariners played under the total in two of their last three games. Detroit averages 4.65 runs per game and averaged 3.33 runs per game in their last three games. They’re batting .240 against right-handers, and they’re facing a starter who gave up three runs in his last four starts. The Mariners average 4.73 runs per game and averaged two runs per game in their last three games. They’re batting .241 against left-handers, and they’re going up against a starter who gave up five runs in his last three starts. Don’t expect these teams to score enough runs to push the score over the total.
