Clock Ticking on Padres
As the season quickly winds down, the San Diego Padres are running out of time to figure things out. San Diego continues to be included in MLB picks and parlays, but often for people betting against them as the Padres try to gain chemistry.
Mike Clevinger will start for San Diego. The long-haired wonder has struggled with a 5-6 record, 4.13 ERA, 1.19 WHIP and 81 strikeouts. Opponents hit .231 against him on the road, where he has a 4.55 ERA.
Clevinger has thrown six innings this season against Seattle, allowing four earned runs. He has allowed nine earned runs in his last two starts on the bump.
San Diego has struggled very much against the spread in 2022. The Padres are 61-80 ATS but an impressive 38-34 on the road. Look for a lot of runs from their potent offense.
Mariners on Playoff Path
Nothing is set in stone, but the Seattle Mariners really appear to be playoff bound. They are often among the favorites in the MLB lines, and for good reason. Seattle is one of the hottest teams in baseball with a 7-3 record in its last 10 outings.
Luis Castillo will take the mound with the fifth-best ERA in MLB. The 29-year-old is 6-5 with a 2.81 ERA, 1.07 WHIP and 141 strikeouts. Opponents hit just .200 against Castillo at home, but the Mariners have won just one of their last four games when he was on the mound.
Seattle dominates the moneyline and the spread alike. They are 76-64 against the spread, which is very impressive for a team that is usually favored. A lot of that has to do with their very underrated pitching staff. Their over/under at home this season is 28-39-3.
