Casper Ruud kept his Madrid Open title defence alive with a dramatic fourth-round win over Stefanos Tsitsipas. The defending champion saved two match points before edging the match 7-6(4), 6-7(2), 7-6(3). It was a tense contest that went the full distance and was decided by small margins in the tiebreaks. Tsitsipas had opportunities to close it out in the third set but could not finish the job. Ruud said afterward that he felt close to going home already and was proud of the way he fought back. The victory extends Ruud's strong run in Madrid and keeps him in the tournament. It is not clear from the provided material who he will face next.
