Sunday's round of World Cup qualifiers involving European nations saw Poland, Czech Republic and Slovakia all pick up important wins.
Czech Republic's World Cup hopes remain in tact after they thrashed Group C basement boys San Marino 6-0 at Stadio Olimpico di Serravalle.
A brace each from Antonin Barak (17', 24') and Vladimir Darida (19', 77' pen) set up the Czechs for victory, while Theodor Gebre Selassie (26') and Michal Krmencik (43') also got their names on the scoresheet.
Armenia recorded only their second win of the qualifying campaign as they beat 10-man Kazakhstan 2-0 at the Vazgen Sargsyan Republican Stadium.
The 64th-minute dismissal of Sergiy Maly swung the match in favour of the hosts as two goals in the space of two minutes from Henrikh Mkhitaryan (73') and Aras Ozbiliz (75') secured victory.
Poland took control of Group E after they emerged 2-1 victors against Montenegro at the City Stadium to go six point clear at the summit.
Lukasz Piszczek scored the winner eight minutes from time after Stefan Mugosa (63') had earlier cancelled out Robert Lewandowski's 40th-minute opener for the Poles.
Slovakia held onto second place in Group F after they claimed a 3-1 win over lowly Malta at the National Stadium, where both teams were reduced to 10 men.
The visitors got off to a flying start when Vladimir Weiss put them in front in the second minute, although Jean-Paul Farrugia restored parity 12 minutes later.
But Jan Gregus (41') ensured the Falcons would go into the break with a 2-1 lead, while there was late drama in the match as Farrugia received his marching orders on 78 minutes before Adam Nemec (84') extended Slovakia's lead and was then dismissed in stoppage time as well.
