Passage: Although tennis was already a major sport by the end of the 19th century, none of the top players turned up for the tournament in Athens. The competition was held at the courts of the Athens Lawn Tennis Club, and the infield of the velodrome used for the cycling events. John Pius Boland, who won the event, had been entered in the competition by a fellow-student of his at Oxford; the Greek, Konstantinos Manos. As a member of the Athens Lawn Tennis sub-committee, Manos had been trying, with the assistance of Boland, to recruit competitors for the Athens Games from among the sporting circles of Oxford University. In the first round, Boland defeated Friedrich Traun, a promising tennis player from Hamburg, who had been eliminated in the 100-meter sprint competition. Boland and Traun decided to team up for the doubles event, in which they reached the final and defeated their Greek and Egyptian opponents after losing the first set.

Question: Who assisted Manos in recruiting competitors?
Boland
