Head to heads are 1-1. They last met at the Australian Open in January 2012. Lacko won on a hard court in 4 sets. Their other match was also on hard courts at the US Open in August 2011. That time Young won in straight sets.
They have quite similar over all results this year. Lacko has been slightly better on hard courts. Most of his recent wins have been in qualifying rounds. He easily beat Fabbiano in straight sets in the last round.
Young saved all 5 of the break chances that Smyczek had in the last round. He has played well during the grass season and his confidence is high.
Home advantage should help Young but I see some value on Lacko to take at least a set. Lay Young below 1.35 in the early games. He starts the match around 1.45.
