Anthony Mazur worked 5 2/3 innings in his ninth major-league start, allowing five hits and four earned runs while walking four and striking out five. He threw 97 pitches, 59 for strikes, providing much-needed innings for an injury-hit Marlins staff. Four of his five strikeouts came on a sharp, late-breaking slider that produced six whiffs and induced weak contact. His fastball sat 93-95 mph and touched 96 with good carry. The combination of a mid-90s heater and a tight, downward-breaking slider underpins his projected upside and why the team values him.
The Miami Marlins didn't necessarily need Anthony Mazur to dominate the Phillies on Wednesday night-they just needed him to eat innings. But what they got instead was a glimpse into why he was such a key piece in last year's Luiz Arraez trade, and why the front office remains high on the 24-year-old right-hander. In just the ninth start of his big-league career, Mazur delivered 5 2/3 innings against one of the National League's most dangerous lineups, allowing five hits and four earned runs in a 4-2 loss for the Marlins. He walked four, struck out five, and threw 97 pitches-59 for strikes.
What stood out most from Mazur's night wasn't his stat line-it was his pitch movement. Four of his five strikeouts came via his sharp, late-breaking slider that Phillies hitters couldn't square up. The pitch consistently induced weak contact and generated six whiffs, either ending at-bats or setting up outs later in the count. Mazur's raw tools were on full display. His fastball sat comfortably between 93-95 mph and touched 96, showing strong carry at the top of the zone. His slider, ranging from the mid to upper 80s, featured sharp downward break and tight spin.
