Ketel Marte is back with the Arizona Diamondbacks as of August 31, per reporter Francys Romero. The Dominican second baseman returns to a lineup that felt his absence — and his Statcast numbers make it clear why Arizona wanted him back in a hurry.
What His Return Means for Arizona
The Diamondbacks get their starting second baseman back with the division race still very much alive. Marte has put up 21 home runs and 67 RBI across 118 games in 2026 — not MVP-caliber on the surface, but he’s the kind of player a team notices more when he’s gone than when he’s there.
Why the .249 Average Doesn’t Tell the Full Story
A .249 batting average makes Marte sound ordinary. Statcast disagrees. His xwOBA of .351 — a measure of what his contact quality should be producing based on exit velocity and launch angle — ranks in the 83rd percentile across all of MLB. In plain terms: he’s making better contact than 83% of big-league hitters.
His average exit velocity of 90.2 mph backs that up. So does his bat speed of 74.8 mph, which puts him in the 81st percentile — one of the faster swings in the league. When a hitter combines that kind of bat speed with quality contact, a low average is usually a product of bad luck on ball placement, not a lack of ability.
There is one real weakness in his game: plate discipline. His chase rate sits in the 36th percentile, meaning he goes after pitches outside the zone more often than the average hitter. With just 41 walks in 519 plate appearances (33rd percentile in BB%), pitchers who work him off the plate can limit the damage. It’s points left on the table.
Marte’s 2026 Numbers at a Glance
- 519 plate appearances

The .249 is the headline number, but Statcast is telling a different story — and in 2026, the radar doesn’t lie.
