Club Atlético Güemes vs San Martín San Juan: match statistics

San Martín San Juan is the slight favorite: in their last 5 matches they scored 6 goals and average 1.2 points per game, while Club Atlético Güemes has scored only 3 goals in that period and averages 0.6 points per game. The visitors create more chances — on average 9.44 shots and 2.67 on target away versus the hosts' 8.4 shots and 2.3 on target — with almost equal xG (1.09 for San Martín vs 1.11 for Güemes). Both teams have 18 goals in the season, but Güemes’ defense looks worse both seasonally and in the short term: the hosts conceded 32 goals this season and 11 in the last 5 matches, while San Martín conceded 19 goals in the season and 6 in the last 5. Güemes, however, have a higher shot conversion rate (12% vs the visitors’ 9%) and keep clean sheets more often (20% vs 11%), but also fail to score more frequently (30% of matches without a goal vs 22% for San Martín), which undermines their chances of reversing the negative trend. Considering the visitors’ advantage in chance creation and the hosts’ poorer defensive form recently, I forecast a San Martín win; probability distribution assumed: home 28%, draw 27%, away 45%.

I back BTTS - Yes as both teams show strong season BTTS rates: home 56% and away 67%, with a 61.5% average well above the league mean of 40%. In the last 5 matches the home side scored 3 goals (0.6 per game) and conceded 11 (2.2 per game), while the visitors scored 6 (1.2 per game) and conceded 6 (1.2 per game), indicating the hosts have recently been prone to conceding goals that the visitors can realistically convert. The home team creates more chances: season xG_for 1.58 vs 1.09 for the visitors and 4.89 shots on target vs 2.67, but the hosts’ shot conversion is 8% vs 9% for the visitors, explaining their lower actual goal return in recent matches. Additionally, the hosts have 33% clean sheets this season vs just 11% for the visitors, and season goals conceded are 32 (home) vs 19 (away), so both teams present elements that favor goals at both ends. Considering the season BTTS split 56%/67%, the clear home chance creation (xG 1.58 vs 1.09) and the high recent average of goals conceded by the hosts (2.2 in the last 5), I estimate the probability of BTTS at 70% versus 30% for No Goal.

I calculated expected goals based on xG and defensive stats: Güemes’ attacking xG is 1.58, San Martín has 1.09, and their xG against are 1.13 (Güemes) and 1.20 (San Martín), yielding an average of 1.39 expected goals for the home side and 1.11 for the away side, totaling 2.50. Season data show both teams frequently exceed 1.5 goals per match — 67% of Güemes’ games and 78% of San Martín’s games finished over 1.5 goals — providing strong support for Over 1.5. The 2.5 line is more borderline: season Over 2.5 is 33% for Güemes and 44% for San Martín, while the league records 30% of matches over 2.5, so with a projected total of 2.50 I assign a slight edge to Under 2.5. The home side generates noticeably more chances (on average 4.89 shots on target and 13.11 shots per match vs 2.67 and 9.44 for the away team) with conversion rates of 8% vs 9%, which increases the probability of at least two goals in the match. Additionally, both teams have 0% of matches over 3.5 this season, making Over 3.5 unlikely; in summary the strongest signal is Over 1.5.

The hosts led at the break in 6 of 9 matches (67%), with their average goals by half-time 0.67 versus 0.33 for the visitors, and average half-time goals conceded 0.11 (hosts) vs 0.67 (visitors). Additionally, the hosts register higher xG: 1.58 compared to 1.09 for their opponents, and average 4.89 shots on target versus 2.67 for the visitors, which, alongside an average of 1.67 points per match versus 0.89 for the visitors, strengthens the likelihood they will maintain a lead. For these reasons I assign the highest probability to the Half-Time/Full-Time scenario of leading at the break and winning the match (1/1) at 55%. I also include the variant of a draw at half-time with a subsequent home win (X/1) at 11% and relatively low chances of a full turnaround (1/2 at 3% and 2/2 at 3%), given that the visitors win only 22% of matches and have lower xG and points per match.
