№ 01Carson Kelly is hitting .268 with a 0.75 OPS across 224 at-bats this season, a workable baseline profile for clearing one total base.
№ 02Zebby Matthews carries a 4.58 xERA over 67.0 innings and a 5.01 FIP, peripherals that suggest a hittable starter under the surface.
№ 03Matthews throws 54.3% fastballs and Kelly owns a .362 xwOBA against fastballs across 153 plate appearances, a direct pitch-mix edge.
№ 04Over Matthews's last 5 starts he has been fading, running a 4.96 FIP across 30.7 innings with recent outings clearly worse than earlier ones.
№ 05The counter is real: Kelly carries a 0.63 OPS in 162 plate appearances against right-handed pitching and is hitting just .236 against righties.
§ 01The analysis
Start with Kelly's bat. He is hitting .268 with a 0.75 OPS across 224 at-bats, a reasonable baseline for clearing a single total base at -143. The pitch-mix leans his way here. Zebby Matthews works off his fastball 54.3% of the time, and Kelly has posted a .362 xwOBA against fastballs across 153 plate appearances, a specific matchup edge rather than a general one. Matthews's underlying profile supports the angle. His xERA sits at 4.58 over 67.0 innings, his FIP is 5.01, and he strikes out only 18.6% of batters, so contact is on the table. He has also been trending the wrong way, with a 4.96 FIP across 30.7 innings over his last 5 starts as his recent outings clearly grade worse than his earlier work. The environment is mixed. Wrigley Field carries a 0.94 run factor and the wind is blowing in toward home at 9 mph at first pitch, though the park still plays to a 1.02 home run factor for right-handed hitters, with first pitch in daylight.
§ 02The call
The risk is Kelly's split. He carries a 0.63 OPS across 162 plate appearances against right-handed pitching, is hitting .236 versus righties, and his slugging against right-handed sliders (.255 over 51 plate appearances) and four-seamers (.313 over 38 plate appearances) both underwhelm. Recent form is quiet too, with 7 hits in 33 at-bats over his last 10 games. The pitch-mix edge on 54.3% fastballs against a fading Matthews is the reason to take the price anyway.
