Starting Pitchers
Los Angeles is scheduled to start Yusei Kikuchi, who enters at 1-6 with a 4.88 ERA and 1.55 WHIP through 62.2 innings. He has allowed 68 hits and seven home runs while recording 60 strikeouts against 29 walks. Seattle counters with Logan Gilbert, who is 12-11 with a 3.81 ERA and 1.10 WHIP through 182 innings. Gilbert has allowed 153 hits and 29 home runs while striking out 197 and walking only 48. Seattle owns a substantial starting-pitching advantage. Gilbert has the lower ERA and WHIP, and his ability to combine strikeouts with limited baserunners gives the Mariners a considerably stronger foundation entering the series finale.
Angels Have Taken Control of the Series
Los Angeles enters Sunday at 62-98 but has won two consecutive games, both against Seattle. The Angels opened the series with a 6-4 victory before following it with a 7-5 win Friday. Before arriving in Seattle, Los Angeles lost consecutive games against the Athletics by scores of 7-3 and 9-7 and was shut out 8-0 by Minnesota. The Angels have therefore gone 2-3 across their last five completed games, scoring 23 runs while allowing 33.
The Angels are batting .234 with 648 runs, 1,253 hits and 153 home runs. They own a .310 on-base percentage and .370 slugging percentage. Los Angeles pitching has posted a 4.26 ERA and 1.35 WHIP with 1,424 strikeouts against 629 walks while holding opposing hitters to a .239 batting average.
Los Angeles has found a way to produce offensively in this series despite mediocre full-season numbers. The Angels have scored 13 runs through the first two completed games and actually own a slightly better season batting average than Seattle. The concern is whether that success can continue against a much stronger starting pitcher Sunday. Los Angeles has only a .370 team slugging percentage, and facing a starter with a 1.10 WHIP creates a considerably different challenge than the Angels encountered earlier in the series.
Mariners Have the Pitching Edge to Avoid Another Loss
Seattle enters Sunday at 74-86 and has lost consecutive games to the Angels. The Mariners have gone 2-3 across their last five completed contests, with their victories coming 6-5 in ten innings against Houston and 2-1 at Colorado. Their losses have come 7-5 and 6-4 against Los Angeles along with a 7-0 defeat against Houston. Seattle has scored 17 runs and allowed 26 during that five-game stretch.
The Mariners are batting .231 with 649 runs, 1,229 hits and 181 home runs. Seattle has produced a .312 on-base percentage and .378 slugging percentage. The pitching staff owns a 4.22 ERA and 1.27 WHIP with 1,371 strikeouts against 432 walks while allowing opponents to bat .252.
There is little separating these offenses statistically. Seattle has scored just one more run than Los Angeles for the entire season, but the Mariners hold an important 28-home-run advantage and have issued 197 fewer walks from the pitching side. Sunday's biggest advantage, however, comes from the starting matchup. Seattle sends out a starter with a 3.81 ERA and 1.10 WHIP against an Angels starter carrying a 4.88 ERA and 1.55 WHIP. After dropping the first two completed games of the series, that pitching discrepancy gives Seattle its best opportunity to reverse the matchup.
Los Angeles Angels vs Seattle Mariners Picks and Prediction
Pick: Seattle Mariners Moneyline
Seattle gets the moneyline selection Sunday. The Mariners have lost the first two completed games of this series, but the pitching matchup changes significantly for the finale. Seattle's scheduled starter enters with a 3.81 ERA, 1.10 WHIP and 197 strikeouts through 182 innings, while Los Angeles counters with a starter carrying a 4.88 ERA and 1.55 WHIP. The Angels are also just 28-51 away from home compared with Seattle's 41-38 record at T-Mobile Park. The offensive numbers are close enough that the starting-pitching advantage becomes especially important, and Seattle also owns the better season-long WHIP. After allowing 13 runs across the first two completed games of the series, the Mariners are positioned for a stronger run-prevention performance Sunday.
Pick: Under 8.5 or Higher
The under is the preferred total if the market gives us 8.5 or higher. Los Angeles and Seattle have combined for double-digit runs in each of the first two completed games of this series, but Sunday's pitching matchup is considerably different. Seattle's scheduled starter owns a 1.10 WHIP and has allowed 153 hits across 182 innings while striking out 197. The Angels have a .234 batting average and .370 slugging percentage, giving Seattle an opportunity to suppress the offense that has produced 13 runs in the series. Los Angeles' scheduled starter is the larger concern for this wager, but Seattle has scored only 17 runs across its last five games and owns a .231 season batting average. At 8.5 or better, the starting-pitching advantage on Seattle's side makes the under the preferred position.
Final Picks: Seattle Mariners Moneyline and Under 8.5 or Higher
