The serve is where this match separates: Mena has been winning 71.8% of first-serve points to Barrena's 64%, and on clay that gap compounds fast. Barrena comes in off a compressed schedule; Mena comes in off a compressed schedule. This one is close to a coin flip, and the lean toward Mena is exactly that — a lean.
