Gagliardi vs Serra Zanetti
Acapulco

Gagliardi's a clear favourite for mine. Her 6-2 6-1 domination of Pin in the first round was rather encouraging while Serra Zanetti surprised many by beating the competent Llagostera Vives. However Llagostera Vives withdrew from Bogata last week with leg tendonitis and was a doubtful starter for this tournament. Head to head's favour Gagliardi 2-0 and while only one was on Clay (Italian Open 2001), both players had similar rankings to their current status (result 6-3 6-0). Gagliardi's slow start to the year is offset by Serra Zanetti's 1win/5loss since January, plus Gagliardi has the advantage of a good Clay workout in Bogata last week.

Pennetta vs Diaz-Oliva
Acapulco
Another favourite at a short price. Pennetta's in the best form of her career as displayed in her strong showing against Schruff in the first round. She did drop an early game but soon closed Schruff out with top rate finishing. Of course Diaz-Oliva is capable of an upset but I think it unlikely. She made the final in Acupulco in 2003 but was very lucky with Suarez's first round retirement and then only beat the likes of Muller, Vaskova and a clay-shy Asagoe. Since then Diaz-Oliva has only beaten one Top-50 player in 20 or so tour games with most of her time being spent on the challenger circuit.My calculations rate Pennetta as a 77.8 per cent chance so there's value at the price.

Pennetta $1.42 @ 5Dimes
