Miami Marlins

The Miami Marlins ended their winning streak with a 5-2 loss to the Cincinnati Reds last Wednesday. Despite a strong offense and a solid batting average, the team has struggled on the defensive side with a high ERA and batting average against. Connor Gillispie is set to start on Saturday with less than impressive stats this season. The Marlins have a power ranking of 25, ranking 13th in offense and 28th in defense. They currently hold a 12-13 record for the season.

Seattle Mariners Analysis

The Seattle Mariners have bounced back from a slow start to win five consecutive series against notable opponents. They have shown strength on both offense and defense, with a decent ERA, WHIP, and batting average against. Luis Castillo is set to pitch on Saturday with promising statistics, including a successful track record against Miami. The Mariners hold a power ranking of 12, ranking at #10 for offense and #18 for defense, with an overall record of 14-12. Miami recently went 1-2 in their last three matchups against Seattle.

Mariners Favorable Pick Against Struggling Marlins Pitcher

In his two road starts this season, Luis Castillo has faced challenges, but has excelled in three home appearances by only allowing four earned runs on 13 hits and six walks in 17 innings. As a result, when considering a side bet, it seems prudent to focus on the Mariners. This decision is supported by the fact that the Mariners have demonstrated a strong .761 OPS and 132 wRC+ against right-handed pitchers in the past 10 days. In comparison, the Marlins have achieved a .722 OPS and 99 wRC+ in similar matchups during the same time frame. Connor Gillispie, the Marlins pitcher, may not inspire confidence based on his recent performance. In his last outing against the Phillies, he surrendered four earned runs on seven hits in five innings, resulting in a no-decision.
