A significant Rajyoga forms due to a sign exchange between the 9th Lord Mercury and the 10th Lord Moon in the Rashi Chart, involving the 9th House (judgment) and 10th House (captaincy, sky), suggesting improved catching and strategic captaincy for the Indian team.

BhavarthaRatnakara, Chapter 3, Shloka 1, I found that when a house’s Lord connects with its Karaka (significator), the house’s outcomes are significantly amplified. Specifically, a relationship between the 3rd Lord and Mars, the significator of sports [3rd House], greatly enhances the 3rd House (sports, self-effort, talent). I

This powerful conjunction forms two Rajyogas: Venus (10th Lord, honor) with Jupiter (5th Lord), and Jupiter with Sun (Lagna Lord). These combinations signal extraordinary achievement and recognition.

As per B.P.H.S chapter forty one if the lord of 6th , 8th ,12 in debilitation and aspecting the lagna its a Rajyoga.

As per B.P.H.S chapter forty one if the lord of 6th , 8th ,12 in debilitation and aspecting the lagna its a Rajyoga. 3rd house is the house of courage, self effort, fitness, heroic valour, legs etc. And to be a successful sports person, strong 3rd house and 3rd Lord is primarily required. The significations of 6th house are enemies , obstacles, fighting in the battle, enemy’s satisfaction etc.

It is important to note that Mars is the significator of the 3rd house, which governs sports. Jupiter, the 5th Lord (representing intelligence and maturity), also aspects the 3rd House of sports, reinforcing the positive influence on athletic pursuits.

The conjunction of the Sun[9th Lord] and Mercury[10th Lord] in the 12th house forms a powerful Rajyoga, although the presence of Saturn indicates potential conflicts, particularly given TippuSultan’s differing views with the rulers of the East India Company. However, Jupiter's aspect further strengthens this Rajayoga, enhancing its overall potency and suggesting that despite challenges, significant opportunities for success would still be present.

After deeply focusing on his chart, I could see the real reason: the Nakshatra exchange between Mercury and Rahu. The Rahu Dasha began on August 11th, 1971, and continued until August 11th, 1989. Mercury, as the 9th Lord (luck, fortunes)from Lagna , resides in its own house (6th House)[ struggle, enemies, challenges] along with the 8th Lord Sun . However, Mercury functions as the 9th Lord from the Lagna and the 10th Lord from the Moon sign (Sagittarius).

This alignment suggests a strong and harmonious interplay of planetary influences, indicating favorable conditions for achievement and recognition in his chosen field.

From Lagna 3rd lord and 10th lord has no connection but from Moon sign 3rd lord and 10th lord is Mars and making the Rajyoga with Saturn the Moon lagna lord by mutual aspect and in D-3 Saturn the 3rd lord of D-1 is placed in 10th house.
