🔥 Pitching Matchup: Merrill Kelly vs. Nick Pivetta
Merrill Kelly (Diamondbacks)
-
ERA: Just over 3.00
-
xFIP: Around 3.50
-
Strikeout Rate: 24.4%
-
Ground Ball Rate: 46%
-
Hard Contact: 34%
Merrill Kelly remains one of MLB’s most consistent arms. He limits home runs, generates weak contact, and works efficiently through lineups. He’s been a reliable bet in the first five innings and team total unders.
Nick Pivetta (Padres)
-
Strikeout Rate: 26.9%
-
xFIP: 3.62
-
Fly Ball Rate: 47%
Nick Pivetta’s strikeouts offer upside, but his fly ball tendencies in a hitter-friendly park like Chase Field present a concern. If he doesn’t miss bats early, the Diamondbacks’ power bats can do damage.
