ARI Diamondbacks vs PIT Pirates Predictions and Best Bets

When scanning the MLB player props for this matchup, I rely on granular data rather than gut feelings. Comparing season-long averages against current lines reveals some ridiculous value, especially when utilizing Kalshi prices over traditional sportsbooks.

Checking the MLB probable pitchers, the road underdog Diamondbacks send veteran righty Merrill Kelly (8-10) to the bump, while the home favorite Pirates counter with Mitch Keller (10-10).

Pick 1: Merrill Kelly Under 5 Strikeouts (56¢ via Kalshi)

Kelly has been a dependable arm, but his strikeout profile does not support an inflated punchout total. My numbers point directly to fading his swing-and-miss stuff. He relies on a pitch-to-contact approach, carrying a meager 5.64 K/9 rate with just 65 strikeouts across 103.2 innings.

Across 18 starts, Kelly averages only 3.61 strikeouts per outing. Expecting him to ring up five Pirates hitters requires an outlier performance. Buying the “No” on 5+ strikeouts at 56¢ on Kalshi is my most wagerable angle.

Pick 2: Ketel Marte 2+ Total Bases (46¢ via Kalshi)

Finding solid value on Ketel Marte to record two or more total bases is an opportunity I am aggressively backing. Marte is an extra-base machine for Arizona, boasting a hefty .457 SLG with 19 home runs and 20 doubles over 101 games.

He averages 1.85 total bases per contest. With 42 of his 104 hits going for extra bases, one swing can easily cash this ticket. The 46¢ price for 2+ bases is incredibly sturdy.

Pick 3: Mitch Keller 16+ Pitching Outs (40¢ via Kalshi)

On the Pittsburgh side, Mitch Keller simply needs to complete 5.1 innings to record 16 outs. He has amassed 325 total outs across 20 starts, averaging 16.25 per appearance.

Keller consistently pitches deep into games. Despite Arizona fielding a potent lineup, Keller’s ability to induce soft contact makes this 40¢ contract highly appealing. This is a brilliant situational angle for MLB pitching outs props.
