Two southpaws, two very different stages of a career, and a Saturday night stage in Glendale. That is why JJ Aldrich against Regina Tarin feels so fun. Fans know Aldrich as the steady veteran who rarely gives away easy minutes, while Tarin arrives unbeaten and ready to find out how her pace holds up against seasoned UFC resistance. Aldrich comes in after consecutive unanimous decisions over Jamey Lyn Horth and Andrea Lee. Before that run, Veronica Hardy beat her by unanimous decision, so the response matters.

Key Storylines
  • Aldrich brings consecutive wins into another high pressure UFC test
  • Tarin tests her unbeaten run against proven UFC experience
  • Two southpaws turn every angle and entry into a puzzle
Finishing Window

The fight is most likely to break open after the opening exchanges, when Tarin’s pace meets Aldrich’s clinch adjustments and both women have real reads.

Tarin’s UFC sample is still small, but her unanimous decision over Ernesta Kareckaite showed constant activity, with enough pressure to make every exchange feel crowded. Here’s the thing. A southpaw mirror match can get weird fast because the easy outside angle is gone. The lead hand, small steps, and timing on entries become huge. Aldrich can slow the rush with clinches, level changes, and smart resets, while Tarin wants space to throw in bunches and force reactions.

Aldrich has also shown that back control is dangerous, as Liang Na learned when those elbows landed. The big question is simple: can Tarin make youth and volume feel overwhelming, or can Aldrich turn this into the measured, physical fight she knows so well? Either way, neither woman gets much room to coast.
