The New York Mets will turn to a pitcher making his MLB debut in an effort to turn things around as they host the Seattle Mariners on Saturday afternoon.
Nolan McLean looks like the real deal, and I’m taking him to combine with Bryan Woo to hit the Under today in my Mariners vs. Mets predictions.
Read on to learn more about McLean and see the best bets for this game in my free MLB picks for Saturday, August 16.
Mariners vs Mets prediction
Mariners vs Mets best bet: Under 8.5 (-110)
Nolan McLean will make his debut for the New York Mets on Sunday after spending the last three years as one of the more intriguing prospects in the majors.
Initially, McLean tried to make it as an Ohtani-style two-way player, but despite his prodigious power, he gave up on hitting due to his high strikeout rate.
But he proved to be a much better pitcher. McLean has an elite spin rate, throwing a curveball, cutter, sweeper and slider all effectively and with tremendous break.
In 2025, he is 8-5 with a 2.45 ERA in 113.2 combined innings at the Double-A and Triple-A levels, and has struck out 127 batters in that time.
Debut pitchers often give MLB lineups the fits, and McLean’s talents would appear to be hard to deal with before seeing him throw once or twice. I’m expecting him to have at least a solid start to his career today against the Seattle Mariners.
Seattle is tossing an excellent starter as well in Bryan Woo, who is 10-6 with a 3.08 ERA and sterling 0.952 WHIP on the season. We should be in for a great pitchers duel at Citi Field today, and I’m taking the Under.
Mariners vs Mets same-game parlay (SGP)
I’m expecting both pitchers to show off their stuff today, and while I focused on McLean’s debut, that includes Woo as well.
I’m taking Woo to hit the Over on his strikeout total, as he has struck out at least six batters in nine of his last 10 starts.
I’m also throwing in a bet on the Mets to (finally) get a win behind McLean.
