2026 Chicago Cubs player profiles: Riley Martin

Today we look at the Cubs’ lefthanded reliever.

Riley Martin hasn’t yet pitched in a regular-season major league game, but this might be the year. The 6’1”, 215 pound Salem, Illinois native has been in the Cubs’ system for five years, rising slowly through the ranks with so-so results until 2025, when he posted a 6-2 record, a 2.69 ERA, two holds and four saves in 63 innings pitched over 47 games. He logged 80 strikeouts but he did issue 35 free passes. A 1.19 WHIP indicates his success, as well.

He was added to the 40-man roster in November 2025.

Martin throws a fastball that sits around 94 miles per hour, a sinker at 92, a slider around 88, and a curve and change that sit around 85. He didn’t throw the sinker in 2025, preferring his four-seam and curve, with the slider a distant third in terms of use. Fangraphs likes his FB, slider, and curve — the FB is 50/50, the slider 55/55, and the curve a nice 70/70. They do give him 20/20 for command — he throws hard, you know.

He was pick No. 22 in the sixth round in 2021, out of Quincy University.

Martin is 27 (turns 28 in a few weeks), so he’s no spring chicken, but perhaps he’s figured things out. No doubt Josh could tell you more if you ask nicely. He’ll pitch in Spring Training so we’ll all be able to see, and that data will be added to last spring’s numbers. It would be far-fetched, I think, to expect him to break camp on Opening Day, but seeing him in Wrigley is very possible — most projection systems like him to taste the coffee this year.

This series will resume on Monday.
