George Steinhauser solos to stage 17 win while Tadej Pogacar increases Giro lead
Steinhauser (EF Education–EasyPost) went alone on the first climb of the Passo Brocon with just over 30km of the 159km 17th stage remaining and continued to open up a sizeable gap over Amanuel Ghebreigzabhier.
With the peloton showing no real urgency in giving chase, the Grand Tour debutant Steinhauser powered up the second climb of Passo Brocon in steady rain to take the victory.
Giro debutant Pogacar had won the 15th and 16th stages to open up a huge gap in the battle for the Maglia Rosa but resisted the urge to make it a hat-trick.
The UAE Team Emirates rider accelerated away from the main group in the final kilometres to put more distance between himself and his supposed general classification rivals.
Pogacar finished one minute and 24 seconds behind Steinhauser to push his overall lead towards eight minutes.
"Well, I really held my horses until the final so it was a really beautiful stage," Pogacar, who has dominated the race almost from the start, said.
"A little bit cold on the last descent but we stretched the legs good on the final climb."
He leads Colombia's Dani Martinez (Bora-Hansgrohe) by 07:42 with Geraint Thomas (Ineos Grenadiers) eight minutes and four seconds back.
Pogacar said Saturday's penultimate stage could be his chance to rack up a sixth stage win.
"The main goal is always to keep the jersey into Rome and not do anything stupid. But there is one really nice stage, Monte Grappa close to Slovenia, we can see what happens there," the Slovenian rider said.
For Steinhauser, it was his biggest senior win.
"To be honest, I didn't really think about much, I just concentrated on the roads in front of me," he said.
"The roads were super wet and slippery so I was just in my zone. I heard on the radio and I was super nervous in the last climb and I heard at one point that he (Pogacar) was attacking but I was already 2km to go so I thought I will make it."
Thursday's 178km run to Padua takes the peloton out of the mountains and will be a day for the sprinters.
