Miami, FL Ricky Dimon
Absences and withdrawals have marked the 2013 Sony Open Tennis event, but Andy Murray–to name just one–is restoring order to the proceedings. Murray earned his second consecutive straight-set win by dismissing Grigor Dimitrov 7-6(3), 6-3 during third-round action on Monday afternoon.

Dimitrov, who lost to Murray in the Brisbane final earlier this season, got off to a fast start. The 21-year-old Bulgarian twice led by a break in the first set but ultimately he could not serve it out at 5-4. Dimitrov also squandered a mini-break advantage in the ensuing tiebreaker and from there he lost the second set in less dramatic fashion.

“He probably got a little bit nervous,” Murray said of Dimitrov, “and that helped me. Once I started to improve my depth a bit I made it tough for him and he started to make more mistakes after that.”

Jo-Wilfried Tsonga followed suit on the show court and hammered Jarkko Nieminen 6-3, 6-3 in one hour and five minutes. Tsonga fought off the only two break points he faced to book a fourth-round showdown against Marin Cilic.

Compared with Cilic (a straight-set victor over John Isner) and Tsonga, Tomas Berdych took a more roundabout way to the last eight. Berdych saved a match point at 3-5 in the second set with a second-serve aces and he survived another in the ensuing tiebreaker. One break in the final frame of play allowed the fourth-seeded Czech to complete his comeback win.
