Starting Pitchers

Texas is scheduled to start Cal Quantrill, who enters at 7-5 with a 2.79 ERA and 1.07 WHIP over 96.2 innings. He has allowed 79 hits and 24 walks while recording 73 strikeouts and surrendering 11 home runs. Seattle counters with Kade Anderson, who is 0-1 with a 5.40 ERA and 1.47 WHIP through 15.0 innings. He has allowed 15 hits, seven walks and three home runs while striking out 11. The numbers give Texas a considerable starting-pitching advantage, with its scheduled starter carrying the substantially lower ERA and WHIP across a much larger workload.

Texas Brings the Pitching Edge

Texas enters this matchup at 71-73 overall and has won two of its last five games. The Rangers recently beat Tampa Bay 8-6 after dropping consecutive games by scores of 6-3 in 10 innings and 7-6. They also recorded a 6-0 victory before suffering a 9-2 defeat. Texas has struggled away from home, however, entering this contest with a 31-41 road record.

The Rangers are batting .243 with 595 runs, 1,163 hits and 165 home runs. They own a .317 on-base percentage and .400 slugging percentage. The pitching staff has recorded a 4.30 ERA and 1.31 WHIP with 1,210 strikeouts and 440 walks, while opponents are batting .250.

Texas has the better offensive profile in this matchup, leading Seattle in batting average, runs, hits, home runs, on-base percentage and slugging percentage. The Rangers have also dominated the season series, winning seven of the first ten completed meetings. Their biggest concern is the 31-41 road record, but the combination of their offensive advantage and favorable starting-pitching matchup gives them an opportunity to overcome that weakness.

Seattle Looks to Defend Home Field

Seattle is 67-77 overall but has performed considerably better at T-Mobile Park, where it owns a 38-34 record. The Mariners have won two of their last five games, including a 2-0 victory over the Athletics in their most recent completed contest. Seattle lost the previous three games by scores of 6-2, 7-6 and 7-4 after opening this five-game stretch with an 8-3 victory on the road.

The Mariners are batting .229 with 569 runs, 1,093 hits and 163 home runs. Seattle has a .310 on-base percentage and .374 slugging percentage. Its pitching staff owns a 4.20 ERA and 1.25 WHIP with 1,215 strikeouts and 376 walks. Opposing hitters are batting .250 against the Mariners.

Seattle's best argument comes from its home performance and slightly better overall pitching numbers. The Mariners have the lower team ERA and WHIP and have allowed fewer walks while recording slightly more strikeouts. The problem is that they enter this matchup with a significant disadvantage between the scheduled starters, while their offense trails Texas across nearly every major category supplied for this matchup.

Texas Rangers vs Seattle Mariners Picks and Prediction

Pick: Texas Rangers Moneyline

Texas is the preferred side because the starting-pitching matchup provides the Rangers with their clearest advantage. Their scheduled starter owns a 2.79 ERA and 1.07 WHIP over 96.2 innings compared with a 5.40 ERA and 1.47 WHIP over 15 innings for Seattle's scheduled starter. Texas also has the better batting average, on-base percentage and slugging percentage while leading the season series 7-3. Seattle's 38-34 home record deserves respect, but the pitching matchup and stronger offensive profile make Texas the moneyline pick.

Pick: Under 8.5

The Under 8.5 is the preferred total if the number is set at 8.5 or higher. Texas' scheduled starter has allowed only 79 hits across 96.2 innings while posting a 2.79 ERA and 1.07 WHIP, and Seattle has scored only 569 runs with a .229 batting average and .374 slugging percentage. Seattle also owns respectable team pitching numbers with a 4.20 ERA and 1.25 WHIP. The Mariners recently played a 2-0 game, while Texas also recorded a 6-0 result during its last five. Take the Under if the total is set at 8.5 or higher.
