The contest, which stretched past four hours, had everything\u2014gritty shot-making, crowd tension, and even a rare coaching violation against Tsitsipas\u2019s father, Apostolos.<\/p>\n<p>Chair umpire James Keothavong was forced to intervene on more than one occasion. At one point, he called out sections of the crowd for their unruly behavior, reminding fans to keep the atmosphere sporting. Soon after, Apostolos Tsitsipas <a href=\"https:\/\/x.com\/Gill_Gross\/status\/1961262421093298387\" target=\"_blank\" target=\"_blank\" rel=\"noopener noreferrer\">received a code violation for coaching<\/a>\u2014something almost unheard of since on-court coaching was broadly legalized in 2022. The infraction stemmed from him delivering verbal instructions to Stefanos while his son was positioned on the far side of the court, an act still prohibited under the new rules.<\/p>\n<p>Despite the distractions, Altmaier\u2019s resilience defined the evening. Having already spent over nine hours on court through ten sets in the first two rounds, the German once again dug deep. Tsitsipas held a match point late in the deciding set, but Altmaier erased it with fearless shot-making and then surged through the closing games to complete the 6-7 6-1 6-4 3-6 5-7 triumph. Altmaier continued to save a series of break points on his own serve in the 5th set before winning the match. Coming to the net after the match, Tsitsipas <a href=\"https:\/\/x.com\/TheTennisLetter\/status\/1961279856546910431\" target=\"_blank\" target=\"_blank\" rel=\"noopener noreferrer\">complained<\/a> about Altmaier&#8217;s use of an underhand serve in the 4th set, and was booed off the court.<\/p>\n<div class=\"getty embed image\" style=\"background-color: #fff; display: inline-block; font-family: Roboto,sans-serif; color: #a7a7a7; font-size: 11px; width: 100%; max-width: 594px;\">\n<div style=\"padding: 0; margin: 0; text-align: left;\"><a style=\"color: #a7a7a7; text-decoration: none; font-weight: normal !important; border: none; display: inline-block;\" href=\"http:\/\/www.gettyimages.com\/detail\/2232613401\" target=\"_blank\" target=\"_blank\" rel=\"noopener noreferrer\">Embed from Getty Images<\/a><\/div>\n<div style=\"overflow: hidden; position: relative; height: 0; padding: 66.66667% 0 0 0; width: 100%;\"><iframe loading=\"lazy\" style=\"display: inline-block; position: absolute; top: 0; left: 0; width: 100%; height: 100%; margin: 0;\" src=\"\/\/embed.gettyimages.com\/embed\/2232613401?et=o_YXJsoeQN1BsAlxY0TuHQ&amp;tld=com&amp;sig=CfLDLPw1Aqg0_qkJ4G8ykQ7N5Ca8lOpHOcd_FfLle0I=&amp;caption=true&amp;ver=1\" width=\"594\" height=\"396\" frameborder=\"0\" scrolling=\"no\"><\/iframe><\/div>\n<\/div>\n<p>For <a href=\"https:\/\/lastwordonsports.com\/tennis\/2025\/07\/04\/goran-ivanisevic-on-stefanos-tsitsipas-ive-never-seen-a-player-so-poorly-prepared-in-my-life\/\" target=\"_blank\" target=\"_self\">Tsitsipas, the loss is another blow at the majors<\/a>, where his recent runs have failed to live up to expectations. For Altmaier, it is further evidence of his knack for producing marathon upsets on the biggest stages. His reward is a third-round showdown against 13th seed Alex de Minaur, though the question will be how much energy the German has left after such a punishing start to his US Open campaign.<\/p>\n<p>Tsitsipas has failed to advance past round 2 of a Grand Slam since the 2024 French Open, this is his sixth consecutive major with an early exit, and he has struggled to win back-to-back matches this season. Altmaier is into the third round of the US Open for the first time, backing up his round 4 appearance at the 2025 French Open.<\/p>\n<p>Main Photo Credit: Susan Mullane-Imagn Images<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Stefanos Tsitsipas\u2019s US Open campaign came to a sudden halt on Day 5, as Germany\u2019s Daniel Altmaier scored another trademark Grand Slam upset with a 7-5 fifth-set triumph.
