San Diego State opened its fall tennis schedule Friday with a four-player group built evenly from continuity and change. Senior Brock Anderson and sophomore William Kleege returned for the Wildcat Invite in Tucson, while Baylor transfer Blake Anderson and freshman Maxime Baur made their first appearances in an Aztec event.

Play began at 9 a.m. at the University of Arizona and continues through Sunday. The field includes players from UNLV, Northern Arizona, New Mexico and New Mexico State in addition to the hosts and SDSU. The individual-event format removes a team dual score, shifting attention toward combinations, match repetitions and decisions that can shape the spring lineup.

Brock Anderson brings the longest SDSU record of the four. He won 10 doubles matches and nine singles matches last season and is one of two seniors on the roster, alongside Aleksi Lofman. September results will not determine the dual season, but his experience gives the traveling group a stable reference when schedules turn quickly between singles and doubles.

Kleege returns with the clearest doubles résumé. He earned all-Mountain West recognition in doubles and collected 25 victories overall, including a 12-3 mark at the top court during the spring. The Tucson draw can test whether that success transfers to a new partner or pairing without the regular-season pressure of a conference point.

Blake Anderson arrives after a strong freshman doubles season at Baylor. He went 19-3 in doubles and 8-3 in singles for the Bears. Those records show efficiency in a different program, not an automatic place in SDSU's order. The fall gives coaches direct evidence of how his return position, communication and preferred side fit the Aztecs' existing options.

Baur supplies the least familiar profile. The Swiss freshman is one of two first-year players in SDSU's incoming class and begins college competition without a domestic season behind him. A three-day invitational can expose him to several styles in a short span while giving the staff a first competitive baseline for conditioning and point construction.

The opponent pool makes that baseline more useful. Arizona supplies the home conditions, while five visiting programs bring players from across the Southwest and Mountain West footprint. Results against varied serves and rally patterns can reveal whether an adjustment works beyond one familiar practice partner. Repetition across three days matters as much as a single bracket win.

The four selections also make the weekend a compact roster study. Two players know SDSU's routines; two are learning them. One returning player has established doubles production, while the newcomers bring results or experience from outside the program. Pairings can be adjusted without moving an entire dual lineup, making experimentation less costly now than in the spring.

No team trophy from September can settle the questions waiting in January. The useful output is narrower: serve patterns under pressure, response after a lost set and evidence that a new partnership improves during the weekend. Tucson is the first entry on SDSU's fall slate, and for half the traveling group it is also the first line in an Aztec record.
