BMW International Open - Day one digest

Everything you need to know from day one in Germany.

David Micheluzzi hit the front, Bernhard Langer had a special day on home soil, Matthis Besard made a hole-in-one and Miguel Ángel Jiménez was robbed on day one of the BMW International Open.

Here is everything you need to know from Thursday at Golfclub München Eichenried.

Big finish puts Micheluzzi ahead

Micheluzzi catapulted himself to the top of the leadeboard with a birdie-birdie finish to take a one-shot lead after day one. The Australian rookie has had an indifferent start to life on the DP World Tour that he has called "absolutely terrible" but he made a mockery of that form in Munich. The 27-year-old carded seven birdies and a bogey in a 66 to get to six under and lead the way from Scot Ewen Ferguson, South African Casey Jarvis, England's Frank Kennedy and American Patrick Reed. "It was kind of all over the shop to be honest," he said. "It was a little bit wayward with the swing early and the putter and short game was elite today. On the back nine I gave myself some chances. I know I'm putting it really well at the moment."

Langer gets farewell under way on 'amazing day'

Langer is making his farewell appearance on the DP World Tour this week, 50 years on from his debut in 1974. The 66-year-old parred his first ten holes from the tenth before he bounced back from a bogey at the par-three second with back-to-back birdies at the fourth and fifth to finish with a one-under-par 71. “The atmosphere was unbelievable," he said. "I teed off at 7:40 so I got to tee off at 7:30 in the morning and it seemed like there were thousands of people and the atmosphere was incredible the whole way around. That was just amazing, and we truly enjoyed it. It was great to play with Marcel (Siem) and with Martin (Kaymer) and you know, I said this could be the last time we ever play golf together and that's reality. So, it was an amazing day."

Matthis Besard makes maiden ace

Besard made his first DP World Tour hole-in-one as he hit a perfect seven iron from 161 yards at the par-three 12th. His effort made it 21 aces for the season.

No practice, no problem for Jarvis

Jarvis only arrived in Munich on Wednesday so his first shot hit at Golfclub München Eichenried was his opening tee-shot. The rookie went on to card a bogey-free 67 and joked that maybe, when it comes to preparation, less is more. “That was actually my first time playing it," he said. "I got in yesterday and didn’t play a practice round. I think in the future I should do this more often, only joking. The course is really good, similar to back home to be honest. I played solid."

Behave, golf ball!

In his 721 events so far on Tour, Jiménez will have seen absolutely everything, but that will not make things like this hurt any less. There is no justice in golf.
